The situation when the bootloader of the device is blocked and access to the Mi Account is lost, is one of the most difficult in the ecosystem of the Chinese manufacturer. Users often encounter a lock screen, where the system requires a password from an account that has been forgotten or linked to an inaccessible phone number. The standard procedure for unlocking through the official Mi Unlock utility in such cases is impossible, since the phone requires authorization before the process begins. Xiaomi has implemented these security measures to protect the owner’s data in the event of theft, but for an honest user this becomes a serious obstacle.
Unlocking Bootloader on a locked device requires understanding that standard methods do not work here without first preparing or exploiting specific vulnerabilities. If the phone is in a "Find Device" state and connected to the Internet, remote lock is active. In this case, the only legal way is to restore access to the account through the support form. However, if the device does not have access to the network or the account is deleted, but the lock is left in memory, there are technical ways to intervene.
It should be noted that any manipulation of the bootloader leads to complete deletion of data. Wipe Data is a prerequisite for the security mechanism. Attempts to circumvent this restriction without data loss in 2026-2026 are almost impossible due to the encryption of the user partition. Next, we will consider the technical aspects of status verification, preparation of tools and algorithms for various lock scenarios.
Diagnostics of the locking state and loading modes
Before you start active, you need to accurately determine the current state of the device. Bootloader can be blocked partially or completely, and the status of the Mi Account can be different from what is displayed in the menu. To get reliable information, you need to transfer the smartphone to a special diagnostic mode called Fastboot. In this mode, the device waits for commands from the computer and displays technical information about the current security configuration.
To get into this mode, you need to turn off your phone completely. Then press the Volume Down and Power buttons at the same time. Hold them until you see an image of a hare repairing an android or a FASTBOOT sign. On the screen, you'll see the status of Locked (locked) or Unlocked (unlocked). If it says Locked, but the phone requires an account when you turn on, then Find Device protection is activated.
⚠️ Note: Being in Fastboot mode does not remove the account lock. If you see Locked status, trying to firmware through Recovery without unlocking the bootloader will result in a signature verification error.
It is important to distinguish between screen locks (PIN-The first one protects the user interface, the second one protects the integrity of the system partition, and unlocking the Xiaomi bootloader on a locked phone is only possible after the Find Device protection is reset, which often requires a full data partition formatting. If the Unlocked status is displayed in Fastboot, but the phone asks for the Mi Account password, the problem is solved easier - through resetting settings in Recovery.
The official method is Mi Unlock Tool
The official unlock path involves having an unlocked screen and accessing settings. If the phone is locked but you can log in (knowing the screen password), the first step is to link the device to your account. Go to Settings → About Phone → MIUI version and click several times on the logo until the message “You became a developer” appears. Then, in the advanced settings, find “Mi Unlock Status” and do the binding.
After the binding, you have to wait until the manufacturer's time is set. Usually it is 168 hours (7 days), but for some regions or new models, the time period can be extended to 30 days. During this period, the Mi Unlock Tool will show a countdown. Trying to circumvent the wait by changing the system time or using modified versions of the utility often leads to locking the unlock function at the server level.
When the timer expires, connect your phone in Fastboot mode to your computer. Launch Mi Unlock, log in to the same Mi Account that's tied to your phone. Press Unlock. It takes a few minutes to reboot and clear the phone completely, and it's a routine that changes the security flag in the bootloader.
☑️ Checking before unlocking
Screenplay: Forgotten password from Mi Account
The most common problem is that the device is locked with an activation screen that requires a password from Mi Account that is lost, in which case it is impossible to unlock the bootloader in the standard way, since the phone will not allow you to perform the binding in the developer settings. The only working option is the procedure for restoring an account through the mi.com website.
If they are not available, use the Forgot Password form and follow the verification instructions. After successfully restoring access and changing your password, wait 24 hours before trying to log in on the locked device (if you can connect it to Wi-Fi).
If you can’t restore your account and need to get your phone back on track, the only option is to flash it through Emergency Download (EDL) mode. However, modern Xiaomi models (Redmi Note 8 and later) require an authorized Mi Account with service engineer rights to log into EDL mode. A typical user will not be able to flash the phone in this mode without contacting a service center or buying paid services from authorized dealers.
What is Auth Bypass?
Use of test points and EDL mode
For advanced users who encounter a brick or hard lock, there is EDL (Emergency Download Mode) mode, which allows you to download the firmware directly into memory, bypassing the bootloader. Most modern models require EDL to be disassembled and special contacts closed on the board, since software input is often blocked.
The process is this: the phone is disassembled, the battery plume is turned off, and there are two test points (usually marked as "Test Points"). TP Or Test Point, which is tweezed, and without letting go of tweezers, you plug in. USB-The Windows Device Manager should have a Qualcomm device HS-USB QDLoader 9008.
Once you enter the 9008 mode, you can try using the Xiaomi ADB/Fastboot Tools utility or Mi Flash Pro. However, as mentioned earlier, the Xiaomi server will check the IMEI of the device. If the account is not untied, the server will return the authorization error. There are paid services that provide temporary access to an authorized firmware account for firmware, but this carries security risks.
| Method | Necessary rights | Data retention | The risk of blocking |
|---|---|---|---|
| Mi Unlock (Official) | Access to the system | No (Wipe) | Low. |
| Recovery Mode | No rights. | No (Wipe) | Medium. |
| EDL (Test points) | Service account | No. | High-pitched |
| Test Point + Bypass | Special equipment | No. | critical |
Reset via Recovery Mode
If the bootloader is locked but the phone is turned on, resetting through the Recovery menu often helps.This will not unlock the bootloader, but will delete the pattern lock and account if the device was not tied to the network after the last lock (FRP lock).
Select a language from the menu (if available), then go to Wipe Data → Wipe All Data. Confirm action. Phone will reboot. If you request a Mi Account after the reboot, then FRP (Factory Reset Protection) protection has worked, in which case you will not be able to log in without entering a password.
💡
If the Recovery menu immediately reboots your phone to the system (MIUI 12/13/14), try pinching the buttons and holding them longer, or plugging your phone into the charger before entering mode.
There are ways of circumventing. FRP Vulnerabilities in the system, using TalkBack or special security APK-files transmitted through OTG. However, these vulnerabilities are quickly closed in new versions of Android and HyperOS. On current firmware, such methods rarely work and require high qualifications.
Risks and consequences of unblocking
When deciding to unlock the bootloader by any means, you should be aware of the consequences. First, the device warranty can be waived, although in many service centers this is not a stop factor unless there was physical intervention. Second, an unlocked bootloader reduces the overall security of the device by making it possible to access data when physically contacting the phone.
Additionally, applications that use Widevine L1 protection (like Netflix in HD) may stop working in high resolution. Banking applications may require additional checks or refuse to work on rooted devices with the bootloader unlocked. SafetyNet (or its Play Integrity API analogue) will flag the device as unsafe.
⚠️ Warning: Once the bootloader is unlocked, Find the Device may not work properly or be disabled. Do not store critical data on the device without additional protection.
Also, consider that every time you flash or reset on an unlocked device, you need to re-authorize your Mi Account if you have the option enabled in your cloud settings, which protects against theft, but creates inconvenience for developers who often change firmware.
💡
Unlocking the bootloader is an irreversible process for data (everything will be deleted), but reversible for the system (you can lock back through Mi Unlock).
