How to restore the factory settings after the vivo mobile phone system crashes and enters the factory mode?

1. Press and hold the power button for ten seconds to forcibly restart the phone;

2. When the phone is turned off, press and hold the volume up button and the power button for 3 to 4 seconds, and then release the button to enter the recovery mode.

Select the "Yes-Delete all user data in Erased Data/Factory Reset" option;

Select "Restart System Now" to restart the phone when finished;

This operation will lose all the data on your mobile phone, so you can back up your mobile phone data before this operation, including contacts, photos and so on.

If it still doesn't work, you can go to the local after-sales service center for testing and handling. The address and telephone number of the after-sales service center can be inquired at the homepage-service-outlet of vivo official website.
