I really need a hint. Tried several things. Even to times i installed a stock rom and did factory reset cause of the FRP tripped. Now I'm able to get acces to stock rom without the need to setup with google account. But still no luck with Oreo roms. Installing rom only runs flawlessly but with gapps there are crashes and no possibility to get playstore working to setup the phone properly. So what did you guys do to make it work? I read a lot through the forum but there is maybe something I've overseen. Any hint is useful. To remind, I got a XT1541. Thanks in advance.
