FP4 and (unofficial) LineageOS

Anyone know if FP4 is going to be added to the official Lineage site anytime soon? Just got a new phone and wondering if it’s worth waiting to set it up if it’s going to be a matter of days or so.

And welcome to the community


@yvmuell thanks and am I right in thinking that after that is merged a PR would be opened against the wiki repo?

Is there an easy (subjective I know) way of installing Lineage in the meantime that would be update-able to main once merged without needing to reflash or not really?

You could install @mmustermann 's build a few comment above yours, fairly easily as it’s a matter of flashing the provided recovery then use it to ADB sideload the build.

As for its ability to be updatable from a future official build, I don’t really know, but I have hopes personally :smiley:

I’m quit sure you’ll have to flash the official build again. An OTA update wouldn’t be possible as the official build is signed with a different key.


Back in the days where LOS became official for FP2, it was possible migrating to official keys…

No idea if this is still valid :wink:

Sounds like I might be best off waiting a little longer then

That one already exists:
This is what the wiki will look like:

LineageOS does not provide an official way to merge from unofficial builds. LOS4microg seems to do so, but I have no experience with the rom at all.


Anyone know if there’s any particular issues with those PRs that need help or testing? Seems like they’ve been open for a while compared to others?

I just ordered the Fairphone 4 and can’t wait to see that lineage goes official online

You seem to have gained some merge conflicts. https://review.lineageos.org/c/LineageOS/hudson/+/335094/1

edit: looks like you’ve solved it and the patch has been merged? We just waiting for an official build now?

@tripplehelix where do you see the patch having been merged? Looks like it still has conflicts and is pending review to me?

https://review.lineageos.org/c/LineageOS/hudson/+/335093/1 Guess it’s something different

Ah that’s the first one, I think this one is needed as well? https://review.lineageos.org/c/LineageOS/hudson/+/335094

Are we waiting for the official release, or is there a flashable build already ? I do not understand much yet, sorry. :sweat_smile:

mmustermann has a build he is releasing each month, won’t be compatable with the official release.

We are just waiting for some changes to be merged on lineageos’s side, then we should have an official release. ETA is between tomorrow and the end of the world.


Thank you very much for your reply. And of course thanks for all for the work on the ROM.

I might be wrong but from the instructions I read here it appears it should not be that much of a big deal to update from unofficial to official… In any case, I’ll have to try it when official gets real.


I’ve never tried that. It sounds easy.
Because of the warning concerning migration builds, I would use the script as described a section later: Signing Builds | LineageOS Wiki

Maybe @mmustermann knows something about this?

Yes, it’s an issue with the signing keys. It’s possible but I’d just flash clean.
