Xiaomi how to find out if the bootloader is unlocked. All methods to unlock and lock Xiaomi bootloader. Disabling driver signature verification

You've probably repeatedly looked through the forum and seen a lot of custom firmware; you may have previously installed them on smartphones. On some devices you can install new software without special problems, and sometimes difficulties arise with the rest. For example, on some Xiaomi smartphones, if the Bootloader is blocked, you will not be able to install custom firmware. People often ask on the forum how to unlock the bootloader of xiaomi redmi note 3 to install unofficial software. On this device, as well as Note Pro, Redmi 3s and some other devices (released since November 2015), the manufacturer locks the bootloader, so in order to fully control the smartphone you must first remove the lock from the Bootloader.

If you confident user Android, you know for sure that an unlocked Bootloader gives a number of advantages to the user:

Ability to install custom Recovery.
The modified Recovery makes working with the device much easier. Thanks to it, it becomes possible to install any firmware and additional scripts.
With the bootloader open, you can install it without any problems Root is right a (superuser). They are needed to work with system files. WITH using Root rights, you can customize the device for yourself: remove unnecessary standard programs, clear your smartphone of ads, overclock the processor, increase battery life, etc.

Let's say you decide to install modified firmware. First you need to check the status of the bootloader.

There are several ways to find out this information. Let's start with something simple.

Method 1 - via smartphone

This check is relevant for Redmi 3 and Redmi Note 3, but it is possible that it will work on your model.

Let's go to system settings devices;
Select the bottommost item “About device”;
Click on the “Kernel” line quickly several times;
In the menu that appears, go to the first item “Software version”.
We find the line “fastboot lock state” under which the bootloader state is indicated: lock – locked, unlock – unlocked.

Method 2 - via computer

If you have Windows

Boot the device in fastboot mode. Press the power button and the lower volume key simultaneously. We connect the smartphone via USB to the computer. On a PC, press the Win+R keys and an input field will open. Enter the command “cmd” to open command line. In the command line, write the command “adb” and press Enter. Find out information about the bootloader. We type the command:

fastboot oem device-info

If the bootloader is unlocked, the display will show: Device unlocked: true.
Otherwise, the value false will be specified.

For linux

Suitable for Linux-like OS (ubuntu/debian).

In the terminal we write adb - sudo apt-get install android-tools-adb android-tools-fastboot
Enable fastboot on your smartphone (power and volume down button)
sudo fastboot devices, a number should appear - this is your device
sudo fastboot oem device-info, bootloader status should be displayed

If you see a message< waiting for device >, which means the command was not executed as an administrator.

Step-by-step unlocking instructions

Be sure to make a backup necessary information. After unlocking, all information can be deleted!

Getting permission

To unlock Bootloader, you must obtain permission from the manufacturer. To do this, we go to en.miui.com/unlock, press the only button there. This link will open the English version of the site; if it’s in Chinese, look at the screenshots. We follow the further instructions:

Unlocking the xiaomi redmi bootloader begins with authorizing your account. Enter the address email, password and log in.

It happens that some users immediately go to the download page for the unlocking utility, while others need to fill out another form:

Enter your full name or just your name;
Select country;
Specify phone number
Reason for unlocking.

Data must be entered on English if the English version opens, if the language is Chinese, then everything is in Chinese, it’s worth using a translator. In the “Reason” field, you can enter the following: “I want to install firmware with Russian language on my xiaomi mi4 smartphone.” We indicate our own phone model.

We tick the box, agree to the terms, and confirm.
An SMS will be sent to your mobile phone with a confirmation code, which you must enter in the text input field, then click “Next”.

At the last stage, you will see a notification that your application has been successfully submitted. The processing time can be three days or more than a week. It is recommended to check the status of the application on the website, since not everyone receives an SMS notification.

We inform you that the method is official, however, on some devices, minor problems may arise during unlocking. Often reinstalling the drivers solves the problem.

Unlocking

To unlock, the official weekly (developer) firmware must be installed - China Developer Version.

For Xiaomi redmi 3 pro and Xiaomi Mi5 can be used global version firmware - Global Developer Version.

Mi4c and Mi Note Pro smartphones already have an UNLOCKED bootloader, which will be blocked when updating to new versions of miui. Therefore, we specifically install the China Developer Version (released only after April 2016) for blocking and then unlock it using the official method.

All these firmwares are official; you don’t need unlocking or other tricks to install them.

Let's say we have waited for the bootloader to unlock, now let's begin the process:

If you want to immediately install unofficial firmware after unlocking, then download it in advance and place it in the device’s memory.
Download Mi Flash Unlock, this is an unlocking program. Us on device Xiaomi Redmi Note 3 Pro unlock bootloader (unlocking the bootloader) using the program the first time .
Turn off the gadget, hold down the power button and the volume key (lower) at the same time to switch to Fastboot mode.
We connect the device to the computer.
We go to the Mi Flash Unlock utility, we see a window with the heading “Disclaimer”, we agree with the rules.

Enter personal data (Mi ID and password). Click the “Login” button.

We wait until the program detects the smartphone, then press the final “Unlock” button.

If the operation was successful, then Bootloader is now in unlocked mode.

All that remains is to install custom Recovery, with which we can install the firmware downloaded in advance into the device’s memory.

How to increase the chance of unlocking approval

When considering your request for unlocking, Xiaomi will check all information about your account. Many accounts are not given the right to an open Bootloader at all, while others wait a month for a response.

To speed up the process, you need to register on the official xiaomi forum and participate in it. We come up with a username, password, and communicate with people, just like on any forum. Your account information will necessarily contain information that you are an active member of the forum. Employees love such users, so they give them the right to unlock the bootloader.

For some very active accounts, as well as those who are members of various development groups, permission is given instantly in automatic mode. You can understand that you are “the chosen one” by the fact that after submitting your application, you are immediately redirected to the program download page.

How many devices can you unlock at once?

There are quantity restrictions on the official website Bootloader unlocks. One account allows you to unlock one device once a month, after 30 days you can apply again for another smartphone. There is no way to bypass the restriction, since permission is given specifically for the account, and not for the smartphone itself.

Possible errors when unlocking

The process of removing protection stops at 50%.

The problem appears due to problems with Xiaomi servers. Just start the process again from time to time, you will definitely get lucky!

Stops at 50% with the message “Not connected Mi Phone”.

The SMS with the confirmation code does not arrive or a Chinese inscription appears. Most likely the quota for Russia has ended.

Use a Chinese VPN or change your number.

A message appears: " Your device isn"t supported by Mi Unlock".

A Network Error appears.

The problem is on Xiaomi's side. Clear cookies (temporary files) in your browser, change IP, use VPS. If you have Beeline, then log in through another provider.

If refused or the wait is more than a month

IN lately Xiaomi no longer refuses to unlock. But if you receive a refusal, then do not despair, follow our instructions.

There are several options:

We wait 15-20 days and re-apply.
Create a second account and submit an application.
We contact support.

Let's look at option 3 in more detail. Write a letter in English and send to [email protected]. The subject of the letter should be “Unlock Your Mi Device”. You will receive a response letter asking for your information. Copy the template they sent, fill in your details and send it to them. The permit is sent in about a day or even earlier.

If for some reason you are refused and nothing helps, which is equal to a 0.001% chance, then you can use a trick.

We switch to Parental Control mode and contact technical support called “Mi Customer Service for Europe”. We write that we cannot exit this mode (this is a popular problem).

There is a high probability that they will then ask for your data and unlock it.

Results

Users who have been unable to install custom software for a long time will now be able to fix this problem. In our article we described in detail how to unlock the bootloader Xiaomi smartphone Redmi 3 using special utility in an official way. It is also suitable for other Xiaomi models. We hope this article answers all your questions. Write your reviews in the comments.

The bootloader (Hboot) is a program that controls the kernel operating system your device so that it boots normally. Moreover, this applies not only to Android, but also to other devices with an OS, such as a PC, laptop, and even an old one. push-button telephone. In addition, it is the bootloader that gives permission to install any programs and firmware. For this reason, users are interested in factory unlocking the bootloader on an Android phone.

Hboot is activated when the device is turned on, and is an analogue of Bios in a computer. It prepares all the data for the kernel, loads it into memory, after which the system starts directly. If its integrity is damaged or something interferes, thanks to the bootloader you can get into recovery mode to clear the data, or perform a reset to factory settings. To do this, before turning on the device, hold down the power and volume down keys and do not release them until booting (in some cases, the combination of buttons may differ).

Why is the bootloader locked?

Manufacturers block for two reasons:

1. Oblige the owner to use the operating system that was developed for his device.

2. Security. Many smartphones and tablets are sold online or in retail stores. In both cases, the seller or intermediary may, at its discretion, add advertising or malicious software that should not exist. For the same reason, Xiaomi began to block the bootloader of devices released after 2016, due to numerous complaints about the presence of viruses in their firmware (which were not initially present).

Benefits of an unlocked bootloader

An unlocked bootloader opens up exactly the same possibilities for the user as on a PC, namely:

Flash any operating system (available for your device).
Installation of individual modules, OS kernels, applications, patches.
Freely migrate between standard firmwares, especially if they are based on different versions Android.
Create without much difficulty backups current OS and/or applications, as well as restore them without using a PC.
Use Dual-Boot and install two or more operating systems, both in internal memory and on an external SD card.
Wider recovery options in case of unsuccessful firmware.

And this is not the entire list of possibilities after factory unlocking Android.

How to unblock

Each device has its own version of the bootloader, which means the unlocking method will differ depending on the model and manufacturer. When submitting an application, the block can be removed by the company itself (especially if you Android developer), but most often, this happens by hacking previously found vulnerabilities in the system.

Risks and consequences

Unauthorized unlocking of the bootloader deprives you warranty service. In addition, your device becomes less secure and vulnerable to hacker attacks. Open bootloader allows you to bypass set passwords, gain access to personal information or erase everything and install different firmware.

Conclusion

There is no need to worry too much about problems with the bootloader, especially when it comes to personal information. Found or stolen devices most often have their data erased, and rarely will anyone restore anything. An open bootloader is more needed by advanced users who know what to do with it, regularly flash something and experiment.

Leave your questions in the comments to the article below - we will try to answer.

Was the article useful to you?

Rate it and support the project!

Many owners Chinese phones sooner or later we wondered how to check whether the Xiaomi bootloader is unlocked. Often, users begin to delve into such details because some devices from this company do not allow them to be reflashed. It is also inconvenient that when buying a phone directly from China, the consumer will not be able to change the operating system to a Russified or other localized system in the future due to closed access to the bootloader.

Of course, a completely logical question immediately arises: “Why doesn’t the manufacturer support the use of its equipment in all corners of the Earth?” Or maybe he's trying to introduce Chinese into more wide application? Of course, this is not true. This happens because it has become popular to counterfeit phones and official firmware from Hiomi. The point is that software may contain a huge number of viruses that can collect data from the phone. This is why all official devices do not allow you to change the firmware. In this article we will look at how to unlock the Xiaomi bootloader.

Another reason why the bootloader is locked

There is another good reason why the Chinese manufacturer prefers to block access to the bootloader. If suddenly a consumer’s phone is stolen or he loses it, then due to the blocking, the new owner of the device will not be able to reflash it and obtain data and personal information. Moreover, each gadget has its own Mi account. Although it is worth admitting that scammers also often wonder how to unlock the Xiaomi bootloader. And, most likely, they have the necessary skills. IN latest versions original software, you can notice new options. One of them has a function that allows you to locate your phone or tablet. The second is responsible for sending absolutely any text to the device’s working screen.

How to determine if the bootloader is locked via PC?

Most often, users encounter this problem when working with Xiaomi phone Redmi Note 3 Pro. Unlocking the bootloader will be easy. However, this process will take from a week to a month.

In order to find out whether the bootloader is unlocked or not on any phone from the Chinese manufacturer "Xiomi", you need to go into a mode called fastboot. You must first connect the device to the computer. After this, you need to write the word “run” in the Start menu. Using it we go to the command line. We enter the letters adb and write a special phrase there. As a rule, it is the same for each phone and looks like this: fastboot oem device-info. After this, one of the inscriptions will appear on the screen: true or false. The first option indicates that the bootloader is activated, and the second indicates that it is not unlocked.

If it does not work, then you must immediately say that it will be difficult to obtain Root rights, even if they have already been activated previously. The fact is that if the initial version of the firmware does not have a locked bootloader, it may become so after a software update. In order to do this, you will have to use a special PC Suite program. Moreover, the update process cannot be carried out via Mi Flash. Therefore, in order to use the usual functionality, you will have to return everything to its original position. The article describes ways to unlock Xiaomi bootloader.

Results

People who are concerned about how to unlock the bootloader of Xiaomi Redmi and all its modifications will now be able to fix the problem they have received. After completing the process, you can freely install custom Recovery, localized firmware, and so on. The article describes official way unlocking the device, which copes with its task in 90% of cases.

On most devices this process is simple, but with some Chinese brands(or even certain models of the line) difficulties may arise.

In particular, to install the software, you must first unlock the bootloader, the methods of which will be described in this material.

Why do you need a bootloader?

A downloader is a special application (process) that allows you to download and install various software on a smartphone. It is present in any device, but can be locked or unlocked.

Most often, users have problems with unofficial software - its installation is blocked on the bootloader, while official applications and programs from the developer are installed freely.

This phenomenon poses the greatest problem when installing new firmware.

The point is that official firmware, which significantly change the appearance or language of the smartphone menu are very few (and for some models they are absent altogether), or they are just as inconvenient, do not expand the functionality and do not meet other requirements.

In fact, the most preferred ones are unofficial firmware developed by enthusiasts, which can significantly improve performance characteristics devices.

In what cases might the user need to reflash the device?

When purchasing non-Russian smartphones directly in China;
If you want to expand the functionality of the device;
If the proprietary shell of the original interface is inconvenient/unusual.

All these problems can only be eliminated by installing new firmware, and the official versions do not solve the problems.

Therefore, you have to download unofficial ones, which the locked bootloader does not allow you to install - when you try to start the installation, a window appears informing you that the process is impossible.

The essence of the problem

This brand blocks the bootloader on all models released after November 2015.

Thus, the user cannot receive on these smartphones the following advantages:

Once you have downloaded any type of unofficial software and transferred it to your device, you can try to run its installation.

If the bootloader is unlocked and functioning normally, then the Recovery process will start, but if the bootloader is locked, then, depending on the model of your phone, nothing may happen at all, a reboot may occur, or a notification will appear stating that this type of operation cannot be performed.

Is there a block?

How to find out if your specific device is blocked? All smartphones released in the winter of 2015 and later have a locked bootloader, but exceptions are possible, as well as a situation where the user does not know the release date of his device.

In this case, it is better to first check whether you need to unlock the bootloader, or whether it is already functioning normally.

There are two ways to do this– using the resources of the smartphone itself or using a computer ( various methods for different operating systems). The verification algorithms are described below.

Via smartphone

This method is the simplest and most accessible, but not always accurate. However, you can check for blocking in this way at any time and anywhere, since for this you only need the smartphone itself, which needs to be checked.

To perform the check, follow the algorithm, below:

Go to the settings of your smartphone or tablet;
Scroll the entire list of settings to the very bottom, to the last item About device;
Go to the About device section;
Find the Core line and quickly click on it several times (up to 10 times, usually);
A new mode will open, similar to the one that appears after activating root rights;

A new menu will open in which you need to find the line Software version;
Go to the item and in the new list find the line FastBoot Lock State;
It is under this line that the status of your bootloader is indicated(the designation unlock indicates that it is unlocked, lock, respectively, indicates that it is blocked).

You cannot change this indicator in this section in any way. Therefore, just close all menus, exit to standard operating mode and reboot the device. After that, proceed directly to the unlocking process.

The method works great on models and some others, so it is possible that it will work on your device.

However, in some cases you cannot use it, because you cannot get extended user rights - and no matter how much you click on the Kernel item, nothing will happen and an additional menu will not open.

If this happens, then you should use a computer to check for blocking.

Via computer

If checking for a lock via a smartphone fails, then you need to check it through a computer after connecting the smartphone to it.

The method is universal, as it works on any smartphone, but it is more complex, as it requires a computer and a USB cable at hand.

In addition, different scanning algorithms are available for different operating systems.

Windows

The most popular OS and the method of using it to view locks is quite simple.

To view the parameters, proceed according to the algorithm:

Turn off your smartphone;
Turn on your PC;
Prepare the USB cable;
Download your smartphone in FastBoot format;
Press and hold the volume down keys (the bottom part of the volume key) and the power on/off key on the device at the same time;
Connect the gadget to the PC using a USB cable;
Press the Win + R buttons on your computer keyboard for a while;
The Run window will open - in the print area, enter the cmd combination to activate it;

Click Enter on the keyboard or OK in the Run field;
The command line is activated, in which you need to enter the abd command;

Press Enter on your keyboard;
Now you can find out direct information about the bootloader - to do this, type in the command line fastboot oem device-info;

Press Enter;
The PC display will show new entry – Device unlocked and designation – if true, then the device is unlocked, if false, then it is blocked.

Now you can close all windows. Basic data about the device has been received. And if it is blocked, then you can proceed to unlocking.

Linux

A different verification algorithm is given for users.

To check the blocking indicator on it, please do the following:

In the command terminal, type abd to activate the command line;

Next, enter the script sudo apt-get install android-tools-adb android-tools-fastboot;
Activate fastboot mode on your own smartphone by holding down the volume down and power buttons simultaneously for a few seconds;
Enter the script sudo fastboot devices on your computer;
After pressing the Enter button, a number will appear on the device screen - this is the international identification number of your device;
Now type the script sudo fastboot oem device-info and press Enter;
The screen will display the status of your bootloader on your smartphone (lock or unlock, respectively);
Now you can close all windows and disconnect the connected phone.

The method is suitable not only for Linux, but also for operating systems based on it - , Debian, etc. even any unlocking will proceed in the standard way. The only problem that may arise is the appearance of the waiting for device notification at any stage of working with the command line; this can be eliminated by running all commands as an administrator.

There is no way to check the bootloader lock on Android using a MacOS computer.

Unlock

Now proceed to the unlocking process itself.

It is quite complex and unique, and it begins with obtaining official permission from the manufacturer.

Obtaining permission

To obtain permission proceed like this:

If you do not have such an account, you must create one on the official website of the brand for further unlocking - without him it's impossible;
A new form will open in which you need to fill out all the fields in order in English– name, country, phone number, reason for unlocking (for some users this form does not open at all and they immediately go to the download page for the corresponding unlocking software);

Check the box for consent to the processing of your personal data and click on the blue-green button in the lower left corner;
On specified number phone will receive a code, which will need to be entered into the only input field on the page that opens;

Click the Next button;
A notification will appear on the screen indicating that the application has been accepted for consideration.

Check the application status in your account. Although in the vast majority of cases a notification of its approval is sent to the specified phone number, in some cases this may not happen.

Important! Because this method completely official, no problems should arise. However, it is still recommended to reinstall the device drivers after receiving it, as some difficulties may still arise.

Actually unlocking

Now that permission has been received, you can directly unlock the device.

To do this, do the following:

Check what firmware is installed on your device - unlocking can only be done if China Developer Version or Global Developer Version is installed;
Download the firmware itself, the Mi Flash unlock program, to which you will receive a link after receiving permission to unlock;
Now put the firmware software into the phone's built-in memory and install the unlocking software on your computer;
Turn off your mobile device and boot it again into fastboot mode in the same way as described above;
Connect the gadget operating in this mode to the computer;
Run the program Mi Flash Unlock;
Agree to the Terms of Use and Disclaimer by checking the appropriate checkbox and click Next ;

Enter personal information– your device ID and password;

Click Login ;
Wait a little - during this time the device will see and identify your smartphone;
The Unblock button will become active - click on it;

This is done by real people who evaluate the activity on your account and may or may not give permission.

If permission is not received, no notification is received; users usually receive approval within one month after submitting the application.

If you are viewing this article, most likely you are facing the problem of locked bootloader on one of your Xiaomi devices. And this is a serious stumbling block for users who want to slightly customize the appearance of their smartphone or reset it to factory settings, for example, if they suddenly forgot the pattern password.

Very often on Xiaomi forums, users share different firmware that seriously changes the functionality of the operating system. But until now, these options were not available to you due to the presence of a bootloader lock, right? Well, any problem can be solved, even this one!

The bootloader, or “Bootloader” in English, is a built-in component on Xiaomi devices that is responsible for loading and stable operation of the operating system. If you have rights to this module, then you can execute various operations and, in fact, you get a completely open operating system. The same situation is with root rights to regular versions Androids. This is a special service that protects the operating system from possible changes by all kinds of applications.

Initially, Xiaomi did not block the bootloader, and it was enabled by default, but recently, almost all devices are supplied to the market with a locked Bootloader, and therefore many questions began to appear on forums, both in Russia and in other countries.

And this is due to the fact that recent years Bypassing the Xiaomi company, many fakes appear that are no different from the original appearance, and even copy the operating system, but are provided with viruses embedded in the code. As a result, after the purchase, the user not only receives a “non-original” device, but also involuntarily becomes the owner of a phone that can independently do mind-blowing things.

Let’s say that without your knowledge, messages will be sent to paid numbers or your phone will be turned into another bot included in shared network botnet for sending spam. And there are a lot of such scenarios. Unfortunately, they are all deplorable for you, and sooner or later you will give up this phone, and all the negativity will go towards Xiaomi.

But such a protection system also has advantages, which we talked about at the very beginning of the article. With an unlocked bootloader, the user can:

Install custom Recovery with different modes;
Modify the operating system of your device by adding various tweaks, widgets, scripts;
Customize your smartphone by deleting standard applications, most of which, indeed, do not provide any benefit at all, but only take up additional disk space and “eat up” RAM.

But all this can be solved using the method that will be discussed in the article. But before you start using it, you must determine whether your bootloader is unlocked or not!

How to find out the status of the Bootloader service (bootloader)?

You can determine it in several ways:

Through the smartphone settings

Go to “Settings” of your device and click on the “About device” tab;
Next, click several times on the “Kernel” item. An additional menu will appear in which you will need to select the “Software version” tab;
Next, find the line with the name – “fastboot lock state”, and see what is written under it. If lock means the bootloader is locked, if unlock means it is unlocked.

Via a Windows computer

You need to boot your phone in a special mode called fastboot and connect it to your computer. To do this, turn off your smartphone and simultaneously press both the “Power” (power) button and the “Volume (down) button”;
Has your phone turned on? Connect to the PC via a USB cable and press the Win + R keys to call the service;
Enter a command in the following format: cmd to launch the command line and enter another one there adb command. Next, press Enter to confirm;
Now enter a command in this format - fastboot oem device-info to get information about the bootloader. If it is locked, the message Device unlocked: will appear with the parameter true. If the value false is next to the inscription, it means it is unlocked.

Via a Linux computer

In the operating system terminal, enter the adb command - sudo apt-get install android-tools-adb android-tools-fastboot;
Next, as in the case of Windows, put your smartphone into fastboot mode;
Now enter the command sudo fastboot devices to check that the system sees your phone. Your device number should appear;
Enter the command sudo fastboot oem device-info, which will show you the bootloader lock status;
If the system issues an alert in this format - waiting for device, this means that the command was not executed as an administrator. Try all procedures again through the administrator!

If in one of the check cases the system reported that the bootloader is locked, then it will have to be manual mode unlock. In principle, this is not difficult, but there are some nuances and important points here. Read our recommendations carefully and strictly follow them.

Preparatory part

Unlocking is impossible without the approval of Xiaomi developers. Yes, yes! Did you think Apple was being too clever? Not so!

You need to go to the page and click the Unlock tab there. This is a special separate page dedicated to this problem. By default, the site opens in English, but some users sometimes have problems and it appears in Chinese. In this case, you can select a language at the bottom right or use Google's page translator.
Here you need to log in with your Mi account, which is linked to the device. Enter the data and log in.
Further events may unfold differently for each user. For some, the utility for unlocking their smartphone is available immediately, but for the majority, they have to fill out additional data and wait for an official response. As additional information, they request: full name, country, phone number and reason for unlocking.

Important to know! All data is entered in English. As a reason, write that you decided to install firmware with Russian on your smartphone or that your smartphone froze and you decided to flash it (of course, all this is in English). Some forums and websites offer to write directly in Chinese. Again, you can use Google Translator.

Check the box agreeing to the company's rules and confirm your phone number with the code that should be sent to your number. If the code has not arrived specified phone number within 10 minutes, then request again. The code will only be valid for 5 minutes, keep this in mind! But don’t press too often, otherwise the system will blacklist your IP.
As soon as the code is specified and the number is confirmed, the system will redirect you to a page in which it will be written that the unlock application has been submitted. You will have to wait approximately from 2 to 21 days. If the application is approved, a message will be sent to the specified phone number notifying you of the successful operation.

Technical part

Things you might not know!

There are certain conditions to unlock the bootloader. As stated on the official website, from one account you can unlock no more than 1 smartphone in 30 days. Moreover, you will not be able to bypass this permission, because the unlocking is given specifically for the account, and not for the phone. Therefore, access to your account must be protected, otherwise your “open system” along with your account will be lost.

We increase the chances of unblocking

When submitting an application, all data is carefully checked by Xiaomi developers, so sometimes refusals are possible. To avoid such cases, you can insure yourself. To do this, create an account on the company’s official forum, indicating your account information there in order to link them. If you actively conduct dialogues and conversations, then employees will make concessions and unblock your account with a bootloader, maybe even a little faster.

Sometimes there are even cases where active users were given permission almost instantly, as if in automatic mode.

Possible problems and their solutions

Difficulties and errors may arise during the unlocking process, but for most of them there are already ready-made solutions.

At 50 percent, the process stopped, and a message in the following format appeared on the screen: - Not connected Mi Phone. The solution is to completely reinstall the drivers on your computer.
The message with the confirmation code does not arrive on the phone. Solution: use Chinese services with a VPN or specify a different mobile number.
When unlocking, a notification appeared with the following content: - Your device isn’t supported by Mi Unlock. The solution is to change the firmware. Your version is not suitable.
The button on the website (green) cannot be pressed. Solution: Allow pop-ups in your browser. Often they are blocked by antivirus.
I can't log into my Mi account! Solution - Instead of login (phone number), enter your ID.
After logging in to the site, it constantly asks you to enter your nickname. Solution - you need to download to your smartphone Miui program Forum Pro V7 and log in with your account. Next, try logging in again using this account on the site.
Unlocking stops at 50% without notifications. Solution - the problem here is not on the user's side. These are brakes on the company's servers. Just try the whole procedure again after some time.
I applied, but they refused after 5-10 minutes. The solution is that this cannot happen, so this is a “jamb” of the system. Apply again.
A notification with the error Network Error appeared. Solution - Again, Xiaomi's problem. Simply delete cookies from your browser, change your IP address, or simply log in from a different computer.

I applied, waited 20-30 days, but was rejected!

Yes, even this happens. And if you are one of the “lucky” ones, try one more option.

You need to wait about 2-3 weeks after the refusal, and then create a second account and contact technical support. But not through the website, but directly to the company’s mail. You will send it to the following address - [email protected]

Be sure to specify the following as the subject – “Unlock Your Mi Device”.

After sending, you will receive a message with a response in which you will be asked to fill in the data. Just copy this template and enter your data next to the items. Most likely, everything will be decided here!

But, if even in this case it doesn’t work out (what an unlucky person you are), you can cheat! Put your smartphone in mode parental controls and write a letter to technical support that you cannot exit it. Developers will send you emails with different solutions to the problem, but reply to all of them that none of the options helped you in the end. In the end, you will be offered to unlock the bootloader itself. Most likely, you will be asked for additional information to do this, so provide it promptly.

How can I block Bootloader back?

If you need to re-lock the bootloader on your device, no requests or checks will be required. You can do all this yourself. Just when flashing your phone using the Mi Flash utility, you will need to check the box next to Clean all and lock at the bottom of the screen. And after the firmware your Xiaomi device will already have a locked bootloader. Please note that the repeated procedure requires all the steps described in this material.
