What if Haier forgets the password on his mobile phone?

Reenter into the ROM. You can get the combination lock released. This method may be a bit complicated for friends who can't brush the machine, but it is much simpler if they can brush the machine.

Unlocking method 2: double wipe

Double wipe is also called double W. Wipe means to restore factory settings, including deleting all contacts, text messages and installed software. Commonly known as hard start, restore factory settings. Note: After erasing, you need to redo the app2sd and root permissions. And the important partition steps of app2sd have to be repeated. Double erasure means clearing cache and memory data.

Now that the mobile phone has been restored to the factory settings, the set password lock will naturally be cleared. This operation is relatively simple, but it may have an impact if there are important files in the mobile phone.

Unlocking method 3: Use adb to delete the forgotten screen lock password.

Operating steps:

1 The mobile phone is connected to the computer, but the data connection is not opened, and it is in charging mode.

2 After unzipping adb.zip on the computer, put the adb file in the root directory of drive C of the computer.

3. In the online diagram, delete *. Key file.

4 Enter adb to restart or manually restart the phone to take effect.
