hallo.. I installed Android Pie on Oneplus X with your guide rom and it worked fine. After a few days after a simple restart the smartp. it is stuck on fastboot mode. Doing reboot with tasteup-volume key, has enter on loop, in and tries to restart continuously so it’s i can not do anything. With the fastboot mode on the pc is written that the device block is on false, i read on line that is not good…. is this important? Does anyone know if it is possible to recover it and how? following the online guides I can do something but I’m not very practical. thank you
