The situation of the smartphone owner forgetting the security code is one of the most stressful in the world of mobile technology, especially for Xiaomi Redmi devices, where the MIUI security system can block access to important information, photos and work documents. Users often mistakenly believe that the only way out is a complete reset to factory settings, which is guaranteed to destroy all files.
However, depending on the operating system version and the type of lock installed, there are methods to bypass protection or restore access while retaining the contents of internal memory, and it is important to understand that the effectiveness of each method depends on the pre-prepared device and the binding of accounts.
In this article, we will discuss in detail the current algorithms for different versions of Android and HyperOS shells. We will not use third-party software of dubious origin, but will focus on regular security features and debugging tools that can help in a critical situation.
MIUI security features and types of locks
The data protection system in Xiaomi smartphones is built on several levels, which makes the unlocking process difficult without special knowledge. The main element is Mi Account, which rigidly links the device to the user's account. When you try to reset your password through Recovery Mode, the system will require authorization in this account, which is a serious barrier for attackers, but can become a problem for the forgetful owner.
There are several types of screen locks: pattern lock, digital key PIN-The pattern lock on older versions of Android (below 5.0) is often stored in the system file gesture.key, deleting which resets the protection, whereas on modern versions, the pattern lock is often stored in the system file gesture.key. MIUI This file is encrypted and linked to a hardware identifier, which is why there is no one-size-fits-all solution for all models.
⚠️ Warning: Attempts to (repeatedly) enter an incorrect password can activate the lock timer or result in (permanent) locking of the device through Mi Cloud servers.
Also worth noting is the difference between a local screen password and a Mi Account password. If you forget your account password, the recovery process goes exclusively through the company's official website and requires access to a linked phone number or backup email. It is almost impossible to reset your account security without this data due to brand security policy.
Use the “Find Device” function from Google
One of the most effective ways that works on most devices with active Internet is remote control through Google services, which allows you not only to find the phone, but also to change the lock settings if the feature was activated in the security settings beforehand.
To implement this plan, you will need access to a computer or other smartphone, go to android.com/find and log in to the same Google account used on a blocked Redmi, and if the device is online and geolocated, you will see its location and control menu.
- 🔒 Select the option “Lock” even if it is already blocked.
- 🔢 Enter a new temporary password that will replace the current forgotten code.
- ✅ Confirm the action and in a few minutes the old password will be replaced with a new one.
After successfully changing the code through Google, try entering a new password on your smartphone screen, and if the system accepts it, you will have access to the settings menu, where you can disable the current locking method or install a new one that you will not forget, which only works if you have an active Wi-Fi connection or mobile network.
💡
If Google Find My Device says “Device Offline,” try sending it to it. SMS with the text "locate" - sometimes it helps to activate data transfer, if the settings allow remote control.
Unlocking with Mi Account and Find Device
Xiaomi smartphone owners have the advantage of having their own cloud service that is integrated deeper than standard Android tools.Find Device feature in the Mi ecosystem allows you to control the screen lock remotely, but only if the device has logged in to Mi acc-un and enabled the appropriate option.
The process begins with a visit to the official i.mi.com website. Sign in using your credentials. In the interface, select the "Find Device" section. If the phone is displayed on the map and has an "Online" status, you will be provided with an action menu.
Unlike Google, Mi sometimes allows you to completely remove the lock, rather than simply replace it. However, this feature is not available on all versions of the firmware. In some cases, the system will suggest sending a command to reset the password, which will be executed the next time you connect to the network.
| Function | Google Find My Device | Xiaomi Mi Cloud | |
|---|---|---|---|
| Password replacement | Yeah (working steady) | Partially (depending on the MIUI version) | |
| The Internet's Demand | I'll be sure. | I'll be sure. | I'll be sure. |
| Depth of integration | System level | MIUI shell level | |
| Probability of success | Tall. | Medium |
If none of the cloud services are working, don't despair. There are more technical methods that require a PC connection, but they also have their limitations and risks. Always check the sync status before trying remote management.
☑️ Checking before remote unlocking
USB debugging method and system files removal
This is the most technically challenging but effective method for power users, and it involves using USB Debugging mode, which must be activated in advance in the Developer Menu. If this option was turned off before blocking, the method will not work.
The method involves connecting your smartphone to your computer and using the Android Debug Bridge (ADB) platform, which you can send to delete files that store password hashes using the command line, and first install ADB drivers on your PC and connect your phone with a cable.
adb shell rm /data/system/gesture.key
adb shell rm /data/system/locksettings.db
adb shell rm /data/system/locksettings.db-wal
adb shell rm /data/system/locksettings.db-shmOnce you have completed these commands, you need to restart the device. At the time of the reboot, the system will not find the files with the keys and can let you on the desktop without entering a password. It is important to understand that on modern versions of Android with disk encryption, this method may not work, since access to the /data partition without unlocking is closed.
⚠️ Attention: Use of teams ADB An error in syntax or deleting the wrong files can lead to a cyclic bootloop or data loss.
What if the ADB can’t see the phone?
Recovery Mode Reset: When Loss Is Unavoidable
If none of the gentle methods worked, the last option is a full reset via the Recovery Mode menu, which is guaranteed to remove any password, but will lead to the complete removal of all user data: photos, contacts, messages and installed applications.
To enter recovery mode on most Redmi models, you need to turn off the phone and then press the combination of power buttons and increase volume. Hold them until the Mi logo appears, then select a language and go to the Wipe Data menu.
The system will alert you that all data will be destroyed, and once confirmed, the formatting process will begin, which will take a few minutes, and when completed, the phone will return to the "out of the box" state, and you will need to reconfigure it and log in to your accounts.
- 🔄 Hold the Power. + Volume Up to vibration.
- 🇬🇧 Choose English (if the menu is in Chinese).
- 🗑️ Press Wipe Data. → Wipe All Data → Confirm.
Once you reboot, the device can request the password from the Mi Account it was previously associated with, which is Anti-Theft. If you don't remember the password from the account, unlocking it will be a very difficult task, requiring you to contact the service center with a check for a purchase.
💡
A full reset via Recovery is a last resort: it is 100% effective at removing a screen password, but permanently deletes all personal information.
Prevention of blockages and important recommendations
To avoid such situations in the future, experts recommend configuring alternative login methods. Biometrics, such as a fingerprint scanner or face unlock, often work even immediately after rebooting on some versions of firmware, if you configure Smart Unlock.
Back up your data regularly. Use Mi Cloud or Google Photos to automatically sync photos and contacts, so even if you have to do a full reset, you can quickly recover important information.
Write complex passwords in a safe place. Human memory is not designed to store many character combinations. Using password managers or a simple paper notebook stored in a safe place will save you from stress in the future.
