Certain fw's u couldn't do that. I was on revision 9 bootloader and did that video and it worked. It was on kg checking but still at rmm prenormal.
Yes my method is only work on Android 8, if downgrade is possible. I have S8 and i am on Android 9 Firmware with Android 8 bootloader, because of this restriction i never update my bootloader :D

Hi there,

Almost a year ago, I flash my Galaxy A8+ (2018) with TWRP and root with Magisk, so fare, no issues. But since 2 weeks ago, i have issues with apps on fullscreen. the screen bug and I need to open the notification panel in order to un freeze, I try to pinpoint the root cause no luck so far, so I'm thinking on perform a factory reset to the device, but not sure how to do it.

My device it's a SM-A730F with Magisk 20.4 and TWRP

Any help I will really apreciate

Thanks a lot
