hi guys
i have a Oneplus 6t upgraded to android 11.
On android 10 everything worked fine, with this version of the software. but after the upgrade to a11, it doesnt work anymore after reboot. first it works, then i reboot and it stays at a black screen. i tried any number of versions, about the same. 9.18.27 either dont start (remain at black screen) or the start and stutter for 10-15 seconds, work a few, then again freeze, and so on. any ideas?
thanks
