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: When the power button is pressed for about 5 seconds, the boot vibration will appear, and then the power button and the volume up button need to be pressed for about 2 seconds to be released, 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.
