I have a pix 7 and tried loading OS. I have drivers and using win11. Cable it ok. I went through webusb-based installer
In developer, oem unlocked. unlocked bootloader all ok. downloaded release ok or stated downloaded. When I click on flash release, error stating need to download release first. Yet I did and did it many times. Can anyone help? I emailed Graphene, no help. Said go to forum. Phone his. bought it new unlocked not from a carrier. I even flashed driod back onto phone and started over with graphene load. Same place it errored. When I flashed back to Driod, no errors at all and phone starts like it was new. In the mean time trying to find someone near me who can take my phone and figure it out.
