How long does it take to refresh OPPOk 1?

Brush machine is to reinstall the system for mobile phone, which can make the function of mobile phone more perfect, but it will delete all user data; Under normal circumstances, the Android mobile phone system is damaged, resulting in functional failure or failure to boot, which can be handled by brushing. If you need to brush the machine, I suggest you go to the nearest OPPO customer service center for free.

Tips:

① After the mobile phone is refreshed, it will only optimize or restore the function of the firmware version, without affecting the normal warranty of the mobile phone. Please rest assured.

② Under normal circumstances, it takes about 20 minutes to finish the machine brushing (not counting the time to download the firmware package).

(3) Contacts saved in the phone body will be lost when swiping the phone, but contacts saved in the SIM card or the cloud will not be affected. It is recommended to back up the data of the mobile phone before swiping the card, or save the contacts in the SIM card or upload them to the cloud for backup.

④ The previously entered fingerprints will be cleared when the models that currently support fingerprint unlocking swipe their cards or restore the factory settings.
