How to clean the b0 16 of Bai Shixun?

When the phone is turned off, press the power-on key and the volume increase key (some phones use the volume decrease key) until the phone is turned on. The following options will appear: Restart the system immediately: Erase data/Restore factory settings: Erase data/Set factory mode, where the volume key is the cursor selection key, which can be used to move the cursor, and the power key is the confirmation key. Select Erase Data/Restore Factory Settings, confirm, and then select Yes to confirm. Phone numbers, text messages and applications that you didn't attach will be cleaned up. Then go back to the previous level, choose to restart the system immediately for confirmation, and wait for a few minutes until the phone is turned on normally.
