How do you do a factory data reset? And can you do this and retain your user data? Do I have to do ...
If you flash the unofficial (or any other) ROM, you don't have to perform a factory data reset separately, just flash your phone in Firmware Upgrade mode. You will lose your user data on any phone after a factory data reset.
Someone know why??? Umidigi have a answer for this? because a i really hate that the system alway close my apps and when i want to continiu use them restart the apps, have some solution?
Which version of SP Flash Tool are you using? Are you sure, you have a UMIDIGI S2 Pro, not an S2 (without Pro)? The S2 Pro is based on MT6757D while the S2 is on MT6757.
