xiaomi bootloader unlock request. How to check if Xiaomi bootloader is unlocked? How to find out if the bootloader is locked

Mobile devices Xiaomi is designed in such a way as to protect all user data as much as possible, as well as to make the operation of gadgets extremely comfortable. Because, in particular, latest versions Haomi phones come with the bootloader in a locked state. On such phones, it is impossible to independently install a new firmware and make any other significant changes to the device configuration.

There is also a security feature in which the system will be locked after several attempts to enter the wrong password on the smartphone. But what if the phone is locked by accident? For example, if you forgot your password and now do not know how to remove the lock mode from your phone.

Today we will learn what to do if Xiaomi phone is blocked and how to remove the blockage. And let's talk about how to properly unlock the bootloader to bypass the ban on flashing your smartphone.

After entering a wrong password

If you use a graphic or digital key to protect your phones, we strongly recommend that you do not forget it. But if this still happened, you can remove the blocking that has arisen. There are several basic ways to do this.

Incoming call. The method will only work on Xiaomi phone Mi if you have blocked it by accident and remember the password. Very often children play mobile gadgets and, without knowing it, they enter the wrong password, which leads to blocking of smartphones. So, we call our phone from another, accept the call and minimize the conversation window. This will allow you to temporarily unlock your device. Now go to settings and remove the password.
Discharging the battery. The principle of operation is the same as in the previous case. Only now we are waiting for a notification about the imminent discharge of the battery and at this moment we click on the notification curtain. After that, you also need to remove the password.
Google account. If you still couldn’t make the phone unlocked, no matter how many times you try again, then use this method. On the tenth attempt to enter the password incorrectly, the system will offer to restore access to the gadget through Google account. You need to choose an option "Forgot graphic key» and enter your own account password. Important condition unlocking - the availability of access to the Internet. If you do not have access to the network activated, installing a SIM card with an already active Internet will help remove the blocking.
Flashing. If the device is still locked, and you don’t know how to remove the block, then it remains to resort to extreme measures by flashing the gadget. The Xiaomi smartphone will definitely be unlocked, but there is also an important drawback of the method - when it is implemented, all your personal data and settings will be deleted. Because better time from time to time to transfer data to another medium, so as not to suffer in such a situation.

Bootloader unlock

As we have already said, Xiaomi phones have an initially locked bootloader. And therefore, in particular, it will be unrealistic for you to do the flashing yourself. But smartphones standard firmware are not always convenient. Therefore, users were forced to look for a tool that would remove this limitation. When unlocking Bootloader you can:

Install custom Recovery.
Fully customize the operation of the smartphone to personal preferences.
Get superuser rights to work with system files.

As in the previous case, there are several ways to make the bootloader unlock. But the beginning of the journey is always the same - getting the manufacturer's permission to bypass the original restrictions. It's not just that Xiaomi representatives decided to block the bootloader.

A request to change the status of a blocked bootloader must be left on the official website of the company. The answer will come in 5-7 days, sometimes you have to wait about two weeks. If you have already made a request, but were denied, then try again. Requests that have been repeated repeatedly are usually granted sooner or later, and users can unlock the phone bootloader. The unlock procedure itself goes like this:

Download the firmware you like and load it into the smartphone's memory.
We download the program.
We put the phone into bootloader mode. You do this in the usual way, holding down the power and volume up keys at the same time.
We connect the gadget to the computer, go to Mi Flash Unlock and confirm that we remove the responsibility for the further operation of the device from the manufacturer.
Click on the button "Unblock" and wait until the procedure is successfully completed.
We put custom Recovery and with its help we install the previously downloaded firmware.

As you can see, there is always a way out. This applies both to situations where the phone is locked as a result of an inadvertently incorrect password entry, and when you need to install new firmware on a smartphone on which Xiaomi has locked the bootloader. The main thing, as usual, is not to worry and do everything according to the rules prescribed in this article. And then no blocking for your phone is critical.

Since the products of the Xiaomi manufacturer are officially supplied to a limited number of countries, and sometimes not all models distributed in the Chinese market arrive there, users are ready to get these devices in all sorts of, not always legal ways, often trying to save money. This leads to the fact that they have to deal with fakes, unofficial operating system, viruses. For this reason, Xiaomi has officially announced its decision to block the Bootloader (bootloader).

In addition to the above, such blocking is also due to the protection of users' personal information in case of loss or theft of smartphones. In practice, attackers who specialize in such thefts can easily access the gadget's data, but if the bootloader is locked, this will significantly complicate its task due to linking the smartphone to the Mi account.

The blocked bootloader does not affect the official Chinese update, but ROOT will become inaccessible. To enable it, the user will need to unlock the bootloader. In addition, Recovery and Mi Flash updates are no longer available.

Xiaomi smartphones for flashing localized software, but in that article a specific device was considered Redmi note 3. Today we will talk about all Xiaomi devices.

The procedure for unlocking the bootloader is not at all complicated, but there are a few nuances that you need to know to get the unlock code. I applied three times to unlock the bootloader, and only the third attempt was successful, and then after a certain feint, but more on that later. We will act in order.

Applying for a bootloader unlock

The whole procedure for unlocking the bootloader can be divided into two stages: the competent execution of the application on the Xiaomi website and the unlocking of the bootloader itself. Previously, you had to apply in Chinese, but a web page in English has recently appeared. Open the link and click on the Unlock Now button.

Enter the details of the MI account to which your Xiaomi smartphone and click on the orange button. If you do not have a Mi account yet, you can register by clicking on the lower left hieroglyphs.

On new page In the first line, enter your name in English. In the second line, select the country of residence. In the third line, enter the phone number without +7. In the fourth text box, paste the following text:

要安装固件的本地化版本

What is translated into Russian means: To install a localized version of the firmware. Put a tick in the bottom line and click on the green button.

A message will be sent to the number you specified, where the pin code will be indicated, which must be entered on a new page. After entering, click on the green button.

If you did everything right, a congratulations page will appear.

The waiting time for permission to unlock the bootloader is approximately 1 to 10 days. But, perhaps, they will refuse you or not send the cherished SMS at all. If after 10 days you have not received confirmation of the application, then we act according to the second scenario.

We write a letter to the support service at [email protected] . In the Subject field, specify: Unlock Mi Device. In the body of the letter in English, we describe the essence of the issue. My text looked like this:

Hello.
I have bought Xiaomi Mi4s and I want to install the firmware with the Russian language. I applied for unlocking the bootloader 10 days ago, but the answer is still no. Please help solve the problem.
thank you.

The next day I received a response asking for the following information:

Original purchase channel (website name):
mi account ID number:
email address:
phone number:
phone model:
Phone system version (settings-about phone for check):
location:

After filling out and sending the necessary information, I prepared to wait a few more days. But by the evening I received an SMS, in which there was a link to the necessary application for unlocking.

Bootloader unlock

After receiving an SMS with a positive response, download and unpack the MiFlashUnlock application to your computer. All necessary drivers for your smartphone model must also be installed. When starting the program, we agree to the Disclaimer.

Enter your Mi account details and click on the green button.

The program will check the status of the application and if everything is in order, the following window will appear.

Turn off the smartphone manually. Press and hold the volume down and power buttons at the same time until a hare appears on the device screen. Release the buttons and connect the phone to the PC.

If the drivers are installed correctly, the application will find the Mi Phone device. After checking the smartphone, the bootloader will be unlocked. Three green checkmarks indicate successful completion of the operation. Now you can install TWRP custom recovery on your smartphone and flash localized software versions. To celebrate, I forgot to take a screenshot with the successful completion of the unlock, so the last picture had to be borrowed from the Internet.

If the verification stops at 50% and the Couldn’t verify device error appears, then this means that your account has not yet been added to the database. You need to wait another 2 to 10 days.

As can be seen from the description, the procedure is not complicated, but very time-consuming. If you are having difficulty unlocking your Xiaomi devices I'll try to solve them.
