Owners of Xiaomi and Redmi smartphones are often faced with the need to remove the lock, but the approaches to solving this problem are radically different depending on the specific situation. If you have forgotten the pattern key or PIN code to access the screen, the procedure is the same, but if your goal is to obtain root-rights or install custom firmware by unlocking the bootloader, then the algorithm of actions is completely different. Incorrect actions in both cases can lead to data loss or turning the device into a โbrick.โ
With the release of the shell MIUI 13 and MIUI 14 based Android 12 the company's security policy has become more stringent. Now, to officially unlock the bootloader, you not only need to link your account, but also wait for 7 days (168 hours), and in some regions, access to the unlocking tool is temporarily limited. It is important to clearly understand what type of locking you are interested in before you begin manipulating system files or settings.
In this article we will analyze in detail both scenarios: restoring access to the device if the password is forgotten and the official procedure for removing restrictions from the bootloader for advanced users. We will look at the pitfalls that can be encountered on modern models of the series Redmi Noteand offer working methods to work around common errors.
Differences between resetting the screen and unlocking the bootloader
The first thing you need to understand is the fundamental difference between the concepts. Lock Screen protects your personal data from prying eyes when your device is turned on. Removing it often entails a complete data reset (Hard Reset), if you do not remember the code. At the same time, unlocking the bootloader is the process of removing manufacturer restrictions on changing the system partition, which allows you to install third-party recovery and modify Android.
Users often confuse these concepts, trying to unlock the bootloader to simply enter the phone, or vice versa. It is worth noting that unlocking the bootloader on devices with active data encryption automatically initiates formatting of the internal memory. This is a security measure implemented in Android 12that makes it impossible to save old data when the bootloader status changes.
โ ๏ธ Warning: Unlocking the bootloader will void the device warranty in most service centers. In addition, after this procedure, some banking applications and contactless payment services will stop working due to a violation of the integrity of the security system.
If your goal is simply to regain access to your phone after a forgotten password, you do not need complex tools like Mi Flash Tool. It is enough to use standard recovery tools or account functions Google. However, if you plan to deeply customize the system, you will have to go through a multi-step authorization procedure on the manufacturerโs servers.
Resetting a forgotten password or pattern on Android 12
The situation when a user cannot get into the smartphone menu is one of the most common. On modern versions MIUI there are practically no opportunities to bypass the blocking without losing data due to the enhanced encryption of the partition userdata. The only working option is to perform a full reset via the mode Recovery.
To enter recovery mode, you must completely turn off the device. Then hold down the Volume Up button and the Power button at the same time. Hold them until the logo Redmiappears, then release the power button while continuing to hold the volume down. You will be taken to the main menu Main Menu, where control is carried out with the volume buttons, and the choice is confirmed with the power button.
In the list of options, select the item Wipe Data, and then confirm the action by pressing Wipe All Data. The system will warn you that all files will be deleted. After confirmation, the formatting process will begin, which will take a few minutes. When finished, select Reboot to reboot. The phone will turn on like new, without any passwords.
โ๏ธ Preparing for a hard reset
There is a nuance associated with protection FRP (Factory Reset Protection). After the reset, the phone will ask for the login and password for the Google account that was synchronized with the device before it was blocked. This is done to protect against theft. If you do not remember your account details, unlocking the device will become extremely difficult without contacting a service center with purchase documents.
Official bootloader unlocking via Mi Unlock
For those who want to gain full control over the system, Xiaomi provides an official tool Mi Unlock. However, the process became significantly more complicated with the introduction of Android 12. The first step is to link your account Mi Account to the device. Go to the settings, select the section Advanced settings and find the item For developers.
In the developers menu, activate the switch Factory unlocking (OEM Unlocking). The system will ask for confirmation and warn about the risks. Next, you need to log in to your Mi Account and connect it to the device status. A message indicating successful binding will appear. Only after this you can start working with the computer.
On the PC you need to download the utility Mi Unlock Tool and install drivers ADB. Launch the app, log in to the same account as on your phone. Switch your smartphone to Fastbootmode by holding down the volume down and power buttons when the screen is off. Connect the device with a cable to the computer and press the button Unlock in the app.
Why does the 7 days error occur?
The Xiaomi security system requires a time delay between account linking and unlocking. This is necessary so that the owner has time to realize his actions and so that the attacker cannot quickly erase data from the stolen phone. The timer starts from the moment of binding in the phone settings, and not from the moment the app is installed on the PC.
In most cases, you will receive a notification that unlocking is impossible right now, and you must wait 168 hours (7 days). During this period, you cannot log out of your account on your phone, otherwise the timer will be reset. After the period has expired, the procedure is repeated and the bootloader will be successfully unlocked.
| Procedure stage | Required actions | Possible risks |
|---|---|---|
| Account preparation | Login to Mi Account, activation OEM Unlocking | Reset timer when logging out |
| Fastboot mode | Hold Vol- + Power, connect to PC | Wrong drivers, bad cable |
| Process unlock | Pressing the Unlock button in Mi Tool | Complete deletion of all data from the phone |
| First boot | Waiting for system setup (up to 10 minutes) | Stuck on the logo when software errors |
Solving common errors when unlocking Redmi
The process does not always go smoothly, especially on devices with new processors Snapdragon i MediaTek. One of the common problems is the "Couldn't verify device" error. It occurs if the account on the phone and in the app Mi Unlock do not match, or if the device was not linked correctly in the developer settings. Check the Internet status and try reconnecting the cable to another USB 2.0 port.
Another common situation is blocking at the server verification stage. This may be due to regional restrictions. In some versions of global firmware, access to unlock servers is prohibited. In this case, you may need to change the region in the phone settings to India or Singapore, although this method does not work on all versions MIUI.
โ ๏ธ Attention: The developer menu interface and account linking conditions may change with each firmware update. Always check the latest requirements on the official Xiaomi community forum before starting the procedure.
If the utility displays a low battery error even though the phone is charged, try disconnecting the cable, rebooting the device into normal mode, checking the charge, and then logging in again. Fastboot. Sometimes clearing the application cache MIUI Unlock in the phone settings before rebinding helps.
Use the original USB cable included in the kit. Cheap analogues often do not provide a stable data transfer protocol necessary for interaction with the bootloader, which leads to a disconnection at a critical moment.
Alternative methods and bypassing restrictions
There are unofficial unlocking methods that are positioned as instant, without waiting 7 days. Such services usually require payment and provision of remote access to your computer or sending the device to a specialist. They use vulnerabilities in testing protocols (Test Point) or specialized boxes for firmware.
The use of such methods is associated with a high risk. You trust your data to third parties, and if the firmware is unsuccessful, the device may receive a hardware lock. In addition, such methods often do not work on new models with a protected bootloader Android 12as vulnerabilities are quickly closed by security updates.
For advanced users there is a method of using EDL Mode (Emergency Download Mode), but to enter it on most modern Redmi an authorized user is required service center account. Attempts to enter this mode through test points on the board without authorization most often result in an "Auth Fail" error.
The official method, after waiting 7 days, remains the only free and safe way to guarantee the functionality of all functions of the smartphone after unlocking.
Consequences of unlocking and refund of warranty
After successfully unlocking the bootloader, an open lock icon will appear in the quick settings menu when you turn on the phone. This is a visual confirmation of the changed status. It is important to understand that some functions, such as Widevine L1 (needed to watch Netflix in HD quality), can be downgraded to L3, which will degrade the quality of the streaming video.
It is possible to return to its original state. You can lock the bootloader again through the utility Mi Flashby selecting the option clean all and lock. However, this can only be done when installing the official global firmware. An attempt to block the bootloader with Chinese firmware on a global device (or vice versa) will lead to the smartphone becoming bricked.
If in the future you need warranty repairs, the service center will easily detect the fact of unlocking. At best, you will be offered paid repairs, at worst, they will refuse service. Therefore, before submitting the device for repair, it is critical to return the software to its factory state and lock the bootloader back.
Is it possible to unlock the bootloader without a computer?
Officially - no. The Mi Unlock utility only works on Windows OS. There are rare exceptions for some older models through special applications on the phone itself, but for devices running Android 12 this option is not provided.
Will my photos be erased when the bootloader is unlocked?
Yes, definitely. The unlocking process initiates formatting of the data partition. All photos, contacts and applications will be deleted without the possibility of recovery if you do not have a backup copy in the cloud.
What to do if the phone is stuck on the logo after unlocking?
The first boot after unlocking can last up to 10-15 minutes. If the phone does not respond for longer, try entering Recovery and resetting the settings (Wipe Data), then reboot the system.
Does Google Pay work after unlocking?
By default - no. System security has been compromised. However, there are methods for hiding root access and bootloader status (for example, through Magisk Hide) that allow you to restore the operation of payment systems, but this requires additional technical knowledge.
