Flashing LineageOS is not working

[AnotherElk]

I messed around a lot with my phone OS-wise for fun and for months now, never got the trouble you describe.

@Lazalatin

That would lead me to the conclusion that only the fairphone support can help…

I guess Fairphone support will be no big help with a TWRP version not coming with Fairphone Open OS and with OSes other than Fairphone OS or Fairphone Open OS. They just don’t officially support community-driven alternatives, understandably.

@Lazalatin

So I tried flashing the Open Source Fairphone OS first knowing they have TWRP delivered with it. It worked

@Lazalatin

Then I tried flashing LineageOS with the now working TWRP. (after factory reset that is)

Factory reset in Fairphone Open OS, which doesn’t do much? …

Porting LineageOS to FP2

I just did a factory reset from within Fairphone Open OS thinking it would reset my phone to a somewhat near initial state … wrong, OS and TWRP are the same and encryption is still there, only every other user-related stuff is gone and the OS starts with the initial setup. Dear diary, “factory reset” nowadays seems to be a funny thing not 100% related to the term I once knew, I’m feeling old … So I wiped everything in TWRP and formatted data again to get rid of the encryption. …

Oh, and always good for testing:
