[G3 Q&A, Help & Troubleshooting] jonas747:
Hey my g3 is broken... After i installed resurrection remix marshmallow i ran into some issues with the screen tunring off a minute after starting and not coming back on (well backlight was on but nothing else), so i decided to revert back to lollipop. First i tried to flash a backup i had done before, that failed as it got stuck on "calculating details" or something like that, then i wiped the system partition cause it seems like that might work? but now everything is broken...

shorter version: had issues with marshmallow, tried to recovery from lollipop backup, it didn't, wiped system, now i can't install roms or anything

- can't flash another version of twrp (kinda funny how it says it succeeded...):

minzip: Can't extract entry to file.

- cant flash roms, (example flashing ressurection remix) again it says it succeeds... but that's obviously a lie:
