Owners of new devices from the Chinese company Xiaomi encountered an unpleasant problem when trying to install Russified or other localized firmware: the bootloader of gadgets turned out to be blocked. A reasonable question arises: why does Xiaomi, whose products are in great demand not only in those countries where they are officially supplied, but also in many others, prevent the full use of their gadgets? Is this really how manufacturers from the Middle Kingdom motivate owners of their smartphones and tablets to study Chinese language? Of course not. It turns out that buyers in different countries of the world often encounter fakes with unofficial firmware installed. Not only do they not ensure the confidentiality of information, but they often turn out to be simply stuffed with viruses. Xiaomi is simply forced to fight for its good name, which is why the decision was made to block the bootloader.

Another reason also applies security, but is already associated with the loss or theft of the device. Attackers can reflash the gadget and gain access to personal information stored on it. If the device's bootloader is locked, then they are unlikely to succeed - after all, each Xiaomi device is tied to its own. In the latest firmware versions, the developers even introduced a couple of new functions, the first of which makes it possible to find out exactly where the smartphone or tablet is located in this moment, and the second allows you to send any information to the screen of a stolen or lost device.

How to determine that the bootloader is locked, and how does this manifest itself?

To check if your bootloader is locked Xiaomi devices, you need to put the device into fastboot mode, then type the command:
fastboot oem device-info
The result can be seen on the screen in the second line of the response message issued. Maybe two options:

Device unlocked: true bootloader unlocked;
Device unlocked: false bootloader is not unlocked (locked).

It is clear that locking the bootloader imposes some restrictions on user actions. For example, it will become unavailable Root access, even if it was received earlier. The fact is that the device will receive official updates “over the air” in any case, and along with them will come a blocking. To return everything to normal, you need to unlock the bootloader. Below we will describe in detail how this is done.

Instructions for unlocking the bootloader:

At the moment, permission to unlock the bootloader is issued to each Mi account automatically, so you can immediately begin the unlocking process. To do this you need to do the following actions:

Slight limitation: from one Mi account it is possible to unlock only one device in 30 days.

Problems that users encounter when unlocking the bootloader:

Problem: The unlocking process reaches 50%, after which it stops (the message Couldn't verify device is received).
Cause: Xiaomi servers error.
Solution: Repeat the unlock attempt once a day - sooner or later your account will end up in the database. Waiting time - from 2 to 10 days.

Problem: Green button is not active.
Cause: Block pop-up windows from visited sites in your browser settings.
Solution: Allow pop-ups in your browser settings.

Problem: At the second point, the unlocking process stops.
Cause: The Android device is running stable version of MIUI.

Problem: Error logging into Mi account.
Solution: Enter the account ID instead of the phone number in the login field when logging in.

As you can see, any problem can be solved, and the situation with unlocking the bootloader of Xiaomi smartphones is no exception. Do you need to lock the bootloader back? No problem, we've prepared

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

There is also a protective function in which the system will be locked after several entry attempts on the smartphone incorrect password. But what to do if your phone is accidentally locked? For example, if you forgot your password and now don’t know how to remove the lock mode from your phone.

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

After entering the password incorrectly

If you use a pattern or digital key to protect your phones, we strongly recommend that you do not forget it. But if this does happen, you can remove the resulting blockage. There are several main ways to do this.

• Incoming call. The method will only work on Xiaomi phone Mi, if you blocked it by accident and remember the password. Very often, children play around with mobile gadgets and, without knowing it, enter the wrong password, which leads to their smartphones being blocked. 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.
• Battery low. 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 shade. After this, you also need to remove the password.
• Google account. If you still can’t get your phone unlocked no matter how many times you try, then use this method. On the tenth attempt to enter an incorrect password, the system will offer to restore access to the gadget via Google account. You need to select an option "Forgot graphic key» and enter the password for your own account. An important condition for unlocking is having access to the Internet. If you do not have network access activated, installing a SIM card with an already active Internet will help remove the blocking.
• Flashing. If the device is still blocked and you don’t know how to remove the block, then you will only have 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 implemented, all your personal data and settings will be deleted. Because better time From time to time, transfer data to another medium so as not to suffer in such a situation.

Unlocking the bootloader

As we have already said, Xiaomi phones have a locked bootloader by default. Therefore, in particular, it will be impossible for you to do the flashing yourself. But smartphones with standard firmware are not always convenient. Therefore, users were forced to look for a tool that would remove this restriction. At unlocking bootloader You can:

• Install custom Recovery.
• Completely customize the operation of your smartphone to suit your personal preferences.
• Obtain superuser rights to work with system files.

As in the previous case, there are several ways to get the bootloader unlocked. But the beginning of the journey is always the same - obtaining permission from the manufacturer to bypass the original restrictions. It’s not just that representatives of the Xiaomi company decided to block the bootloader.

A request to change the status of a blocked bootloader must be left on the company’s official website. 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 refused, please try again. Requests that have been repeated multiple times are usually granted sooner or later and users can unlock the phone's bootloader. The unlocking procedure itself goes like this:

• Download the firmware you like and load it into the smartphone’s memory.
• 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 relieve the manufacturer of responsibility for the further operation of the device.
• Click on the button "Unblock" and wait until the procedure is completed successfully.
• We install custom Recovery and use it to 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 unintentionally incorrect password entry, and to cases 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.
