What if Huawei's SMS crashes?

If your mobile phone has been showing 3G life and can't access the mobile phone system, please press and hold the power button 10 second to turn it off and then turn it on. Still can't turn on the phone, please try to restore the phone to the factory settings. First, press the power button and the volume+button of the mobile phone at the same time when it is turned off to enter the recovery mode.

Subsequent operations to enter recovery mode are as follows:

1. Use the volume+ and volume- keys to adjust the light bar to "Erase data/restore factory settings", that is, "Erase data to restore factory settings", and press the power button to confirm.

2. Use the volume+and volume-keys to adjust the light bar to "Yes, delete all user data", and then press the power button to confirm.

3. Wait for a while until the next screen appears, select "Restart the system now" to restart the phone, and press the power button to confirm.

If it still can't be opened, please bring the warranty certificate to the nearby Huawei customer service center for inspection and maintenance.
