I've been reading online about flashing these GSI roms but I've seen multiple different methods. Some say use TWRP others say fastboot, or should I use SP flash tools...? And what are the proper wipes to prep for GSI flash? I've seen some say wipe everything except internal and others say just wipe dalvik/cache, and still others that say you must wipe in stock recovery then flash and boot twrp to flash system image...? Can any Umidigi Pros enlighten us a little? I'm sure google will bring more people to this page in time...or not?
I have flashed some GSI ROMs but everyone I've tried I cant seem to get root with Magisk. Magisk shows to be installed but when root apps call for root it just sits there and times out and I never get the prompt to grant root. This means I can't edit the APN which means no data which is not an option.
PS I've tried posting over in Umidigi community but it seems like a ghost town over there and I don't want to hijack any of the other threads here for our device as none of them are related to this issue.
