What if Huawei forgets the screen lock code? I failed to upgrade by pressing the volume button!

If you forget the screen lock password or enter a password that cannot be unlocked, please try to solve it in the following ways:

Make sure the password has been changed first: it is possible that someone else changed the lock screen password of the mobile phone. I suggest you confirm whether the password has been changed by people around you.

2. Confirm whether to use privacy space: If you have enabled privacy space and set a password for screen locking different from that of the main user, and the password type is different, the corresponding password type will be displayed from which interface to lock the screen, and you may confuse the two passwords. Please enter the corresponding password to try to enter the system.

Tip: If you just forget the privacy space, you can enter the main space.

3. Please confirm whether multi-user is turned on: If the screen lock interface you are in is a sub-user interface, you can't unlock it with the main user password. I suggest you switch to the main user and try to unlock it. Switching method: Click the multi-user avatar to switch.

Fourth, restore the factory settings: If you confirm that you have forgotten the password of your mobile phone and need to unlock it, we can help you forcibly restore the factory settings of your mobile phone. However, the data in the mobile phone will also be erased and cannot be recovered, so I suggest you recall the password you may have set.

If it is determined that the password cannot be recovered, it is recommended to follow the following steps to restore the factory settings:

1. The phone is turned off and the USB cable is not connected. Press and hold the power button and the volume up button at the same time, wait for 5 seconds after the phone vibrates and enter the recovery mode.

EMUI 10。 X/ 1 1.0。 Magic UI 3. X/4.0: When the power button is pressed for about 5 seconds in the power-off state, the boot vibration appears. At this time, it is necessary to press and hold the power button and the volume up button for about 2 seconds to release, and the black screen will enter the recovery mode after about 10 seconds.

Mate 30 RS, Mate 30 Pro and Mate 30 Pro all have no physical volume keys. After the phone starts to vibrate, press the power button 5 times to enter the recovery mode.

If you can't enter the recovery mode, but your device is connected to the Internet and the function of finding mobile phones is turned on, you can also try to log in to Huawei cloud hosting official website (cloud. Huawei. com)- find devices, and choose to use the same Huawei account password as the device to erase the data after logging in. After the data is successfully erased, it is irrevocable, which is equivalent to forcibly restoring the factory settings.

2. Press the volume up and down keys to select clear data, and then press the power button to confirm.

Some products support the restored touch screen operation, which can be selected by clicking on the touch screen.

3. By pressing the volume up and down keys, choose to restore the factory settings, and press the power button to confirm.

Some models need to enter "Yes" for secondary confirmation before returning to factory settings.

4. After the factory settings are restored, click the Back button, and the phone will return to the recovery interface. Click to restart the device.

If Huawei Cloud Backup is enabled on your mobile phone, you can restore data through cloud backup after factory settings are restored.
