This guide covers all the current unlocking techniques, from standard reset procedures to more complex engineering manipulations. We will look at the nuances of working with Recovery Mode, the features of deleting authorization files and methods of bypassing security through the computer.

Preparation for the procedure of unlocking the device

Before you start active actions to remove the lock, you need to make sure that the device and your workplace are ready.The battery charge of the smartphone should be at least 50-60%, as the reset or flashing process can take time and the interruption of power will lead to critical errors of the system. If the phone responds to presses, but does not let it go beyond the lock screen, try to connect it to the charger in advance.

However, if the phone is completely locked, this step is often skipped and the user should be aware of the risks of losing personal information. Full Hard Reset is guaranteed to delete all user data, including photos, contacts and apps.

You’ll also need a stable internet connection on your computer or other smartphone to download the necessary gates and drivers. Redmi 4A often uses dedicated ADB and Fastboot drivers that need to be installed in advance, without which the computer may not recognize the device in debugging mode.

Remember that modern versions of MIUI have enhanced security, and if a device search was enabled, the system will require you to enter a password from a previously synchronized Mi Account after a reset, so knowing your credentials or being able to recover them via email is critical to success.

Resetting with Recovery Mode (Hard Reset)

The most common and effective way to unlock the Xiaomi Redmi 4A without access to the system is to use the Restore Mode, which allows you to completely reset all settings and user data, returning the phone to factory state.

The login procedure is standard for most Xiaomi devices, but requires precision in timing presses. Turn off the smartphone completely. Then press both the Volume Up and the power button at the same time. Hold them until the Mi logo appears, then release the power button, continuing to keep the volume. In a few seconds, the Recovery menu will open.

In the menu, the navigation is done with volume buttons (up/down), and the power button selects the item. You need to find the Wipe Data section and confirm the action. The system can ask for consent several times, as this is an irreversible operation. After the process is complete, select Reboot to restart.

It's worth noting that after this procedure, the phone will turn on longer than usual, up to 5-10 minutes, which is normal behavior when the system is first initialized, and if the device requests a password from a Mi Account, it means that the anti-theft feature worked.

Delete the password file via ADB (without data loss)

This method is suitable only for those cases when the debugging was pre-activated on the smartphone. USB If these conditions are met, you can try to delete the system file that stores the hash of the pattern lock or PIN-code, while retaining all personal data.

To implement this method, you will need a computer with an installed Android platform package. SDK Platform Tools. Connect the blocked Redmi 4A PC through quality USB-Open the command line (CMD) PowerShell in the tool folder ADB. Enter the communication check command:

adb devices

If a device has been listed, the connection is established. You need to get superuser (root) rights as part of the ADB session. Enter the adb shell command, and then try to get rights via su. If the phone is not rooted, this method may not work without the unlocked bootloader, but on older versions of Android sometimes rolls the removal of key files directly.

The files that are responsible for blocking are usually located in the /data/system/ directory. The key files are gesture.key (pattern lock), password.key (digital password) and locksettings.db. The deletion command looks like this:

adb shell rm /data/system/gesture.key


adb shell rm /data/system/password.key




adb shell rm /data/system/locksettings.db

Once the commands are executed, reboot the device with the adb reboot command. When you turn on, the lock screen may remain, but any password or finger movement entered must be accepted by the system. This method is the most gentle, but unfortunately, on newer versions of MIUI with data encryption enabled, it is often not available without an unlocked bootloader.
