I recently bought a second hand pixel 6a in mint condition for a good price. Before installing grapheneOS, I updated the device until September security patch and of course tested the phone in all aspects to be sure there was no hardware of software issues (nothing so far)
After opening my chromium browser, I installed grapheneOS on my 6a (web-usb installer)
Shortly after I started to use the phone, screen became unresponsive a couple of times, I had strange glitches with weird pixels appearing on screen, vanadium closing by himself, launcher not responding and at the end crashing. After a few reboots, the phone would no longer boot at all (stuck on white graphene logo) sideloading OTA update would not help (looks like the file system was corrupted)
I erased non stock key, reflashed stock os, reflashed graphene but same problems occurs
I was wondering if this is actually happening because of faulty google firmware
(in July a lot of people had their pixel 6 bricked, some could not even access recovery and stuck forever until device was send to repair)
I just don't know what to do and I don't want to use stock google on my device, I love graphene
Any help would be very appreciable
