Faced with a sudden lock on a Xiaomi or Redmi smartphone is always a stressful situation that can take you by surprise: The device turns into a useless piece of glass and metal if you forget the pattern lock, digital pin code or, worse, lost access to the tied Mi Account. Modern MIUI security systems work flawlessly, protecting user data, but it is this reliability that becomes an obstacle when access to the gadget is required by the owner himself.
In this article, we will take a look at all possible lock scenarios and how to fix them, from simple recovery methods through the cloud to complex manipulations with the bootloader. You will learn how to unlock the screen, what to do when an account is blocked banner appears, and how to unlock the bootloader for flashing. It is important to understand that each method has its own risks and consequences, so careful study of the instructions will help you avoid turning the smartphone into a “brick”.
Before you start active actions, you need to clearly identify the type of lock, this can be a standard Lock Screen, Mi Account protection (Find Device) or Bootloader lock. The correct definition of the problem depends on the choice of recovery strategy, so do not rush to press random buttons, but analyze the current state of the system.
Types of locks on Xiaomi and Redmi
Understanding the differences between security is key to successful unlocking, and users often confuse locking with account binding, although the mechanisms of their work are radically different. The lock screen is the first line of defense that can be avoided by resetting, while Mi Account is tied to the hardware of the device at the server level of the manufacturer.
Locking the bootloader is a separate layer of protection that prevents you from installing unofficial firmware or system modifications. If your device just asks for a password when you turn on, that's one scenario. If after a reset, the phone requires you to enter a password from a Mi Account that was synchronized earlier, that's Find Device protection. Ignoring this difference can cause you to make a full reset, but still can't log in.
💡
Remember: Recovery resets the screen password, but does not remove the Mi Account binding if the Find Device function was active.
Also worth mentioning is the IMEI blocking, which is less common and usually associated with technical malfunctions or illegal actions of the previous owner.
| Type of lockdown | Cause of occurrence | Elimination method | Risk of data loss |
|---|---|---|---|
| Screen (PIN/Graphics) | Forgotten password by the user | Wipe Data / Resetting through the Cloud | High (data deleted) |
| Mi Account (Find Device) | Account binding prior to reset | Entering an account password or unlocking the bootloader | Critical (without password, entry is impossible) |
| Bootloader (Bootloader) | Attempt to reflash without a license | Official Unlocking through Mi Unlock | Complete deletion of all data |
| Locking the operator | Sim-Lock from a mobile operator | Entering a special unlock code | Absent. |
Unlocking the screen through Mi Cloud
The most civilized and safe way to remove locks from a Xiaomi phone is to use the Mi Cloud service, which only works if the locked device has the Internet turned on and the Find Device function is activated. If these conditions are met, you do not need to reset the phone to factory settings, although data security is still not guaranteed 100%.
First, you need to go to the official website of the cloud service from a computer or other smartphone. Enter your credentials (login and password from the Mi Account). After successful authorization, the system will suggest choosing a device from the list of associated gadgets. Find your Redmi or Xiaomi in the list and go to management.
In the device control menu, you're interested in the "Block" or "Unlock" function. By clicking on the corresponding button, you send a command to the server, which in turn will communicate with the phone. If the device is online, the locking of the screen will be removed or the password will be changed. Note that this method may not work if the phone is in flight mode or discharged.
What to do if the phone is offline?
It is important to note that after the procedure of unlocking through the cloud, it is strongly recommended to immediately change the password from the Mi Account, this is a precaution in case access to your account was obtained by third parties, and the security of personal data should be a priority, especially after an incident with loss of access.
Hard Reset: Reset with Recovery Mode
If cloud-based methods are not available, the only option is to force resets through the Recovery menu, which is guaranteed to remove a forgotten pattern lock, pin code or pattern, but also destroy all user data: photos, contacts, messages and applications.
To enter recovery mode, you need to turn off your smartphone completely. Then press the button combination: usually Volume Up + Power. Hold them until the Mi logo appears, then release the power button, continue to keep the volume. In a few seconds, the main Recovery menu will open.
☑️ Algorithm of actions in Recovery
The menu is navigated by volume buttons (up/down), and the choice is confirmed by the power button. You need to find the Wipe Data item and select it. The system will warn you about the loss of data — confirm the action by selecting Wipe All Data. The formatting process will take from a few seconds to a couple of minutes.
⚠️ Note: On some new versions MIUI After resetting via Recovery, the phone will require you to enter a password from a Mi Account that was synced earlier. If you don't remember this password, a standard reset won't help you - the device will remain locked.
Once you have finished, select Reboot -> Reboot to System. The first launch will take longer than usual, as the initial Android setup is underway, and be prepared to enter your Wi-Fi and Google account details for verification.
Unlocking the bootloader (Bootloader)
Unlocking the bootloader is a more complex process that is often necessary to unblock the Mi Account if the password is lost, or to install custom firmware. Officially unlocking requires permission from Xiaomi and the use of a special utility Mi Unlock Tool.
The first step is to apply for unlock via your phone settings. Go to Settings -> Advanced Settings -> Developer (if the menu is hidden, click 7 times on the MIUI version). Select bootloader Status and link your account. After that, wait 7 to 360 hours (depending on region and MIUI version).
When the wait period expires, connect the phone to your computer in Fastboot mode (clutching Volume Down + Power). Run Mi Unlock on your PC, log in to the same account and press the unlock button. The program will warn you to delete all data - agree.
💡
Unlocking the bootloader is officially possible only from the linked account and after the end of the waiting timer. Bypassing the timer through third-party services carries high risks.
There are also paid methods of unlocking through server services that allow you to remove the restriction without waiting a week. Such services provide specialized services, but they require payment and transfer of device data (IMEI) to third parties.
Elimination of blocking by advertising banner
Special attention should be paid to the situation when the screen is blocked by an intrusive banner advertising or a virus-miner, which is often confused with system locking. If the phone works, but constantly comes out advertising on the full screen, most likely you installed a malicious application.
Try entering Safe Mode. To do this, press the turn off button on your desktop, and when the turn off icon appears on the screen, press and hold it. The system will suggest that you go to Safe Mode. Only system applications are downloaded in this state. If the ad is gone, delete the last programs installed.
If you can't log in because of the banner, try running Recovery and resetting as described above. ADB (Android Debug Bridge, if the phone was enabled debugging USB. This allows you to remove harmful APK-file without total data loss.

Prevention and safety advice
To prevent a lockdown from happening again, it is important to follow basic digital hygiene practices: regularly check if sync is activated with Mi Cloud and Google Account. Backups of contacts and photos can save you at a critical moment, even if the phone itself has to be reset.
Write your passwords in a safe place. Using password managers or a paper notebook that is kept secure is better than hoping for memory, and you should not turn off Find Device unless absolutely necessary, as it is the last frontier of protection against theft.
⚠️ Warning: Never buy used Xiaomi phones without first checking for Mi Account binding. The seller can hide the fact of the lock, and you will be left with a non-working device that cannot be activated.
Keep an eye out for system updates. Xiaomi regularly releases security patches that close vulnerabilities used by hackers to lock devices. Update MIUI through the settings menu to stay secure.
