What should I do if I forget the privacy protection password of OPPO SMS? Please master the advice!

I suggest you unlock it after sale, because there are special tools to unlock it after sale, and the data in the machine will not be deleted. When decrypting, you need to bring the purchase voucher (invoice), warranty card and a copy of your ID card. You can also press and hold the power button for ten seconds to enter the power-off state (if you need to turn off the battery, please remove the panel and reinstall it). Then press and hold the power button and the volume reduction button at the same time to enter the recoveryr mode, and select the power button through the volume button to confirm, double-click Clear (restore factory settings and clean up the cache to erase data/factory reset and erase the cache partition), and then select Restart the phone, which can also unlock the phone, but it will delete the data in the machine (such as contacts, SMS, notes, software, etc.). ).
