As my GPS is not usable on OpenOS, I would like to flash back Fairphone OS 1.5.1 until I understand what is happening… But it looks like it’s not as easy as flashing a ZIP. I tried using the updater and using TWRP, without any luck. I guess partitions are not the same so the zip won’t apply. I could not find any help on this topic… I will try using fastboot, but I’m not sure that will work either.
Did you use the right file (Going Back - OTA Switcher)?
Ok, thanks, I don’t know how I did not see that. Thanks !
