(First time poster here, so my apologies if this post is misplaced in the forum. Did my best to try and place it in the right subsection)
I bought a FP5 about a year ago, with the firm intention to degoogle it with e/os. After looking up installation guides, I chose the a14-community version because at the time the official one was not available for a14, which was my stock OS. I’m super happy about it, thanks a lot to the devs and community !
Recently, I noticed some weird behavior with quick charge. After looking up for info in the forum, I thought about updating my e/OS version just to be sure it’s not a software bug which was solved already. At first updates were done OTA, but I realized I have e/os 3.1.4 and my phone won’t upgrade anymore because newer versions are for a15 and my phone won’t upgrade to them OTA because I have the community version.
So here’s my question : with my FP5, is it possible to update from a14 e/os 3.1.4 community to a15 e/os 3.4 official without losing data that’s currently on the phone ? If yes, could a nice person point to the specific instruction guide to do so ?
Thanks a lot to people who will read my long post, and thanks even more to those who may reply
Regarding switch from ‘community’ to ‘official’ without a clean install, it islnot the correct way according to /e/OS team, though it works (i also switched for official to community on Pixel 4a). There could be sideeffects we can’t know, I did not really encounter anything back then.
Thanks to both of you for this quick and helpful feedback !
One quick follow-up question : Piero was mentioning the local update may fail due to signature mismatch, and mihi replied by saying it should work … I could try it after a backup, but what’s the outcome if it fails ? Would it just not update, or can it have more serious consequences (having to do a full reinstall or worse, bricking the phone) ?
For a clean install with guaranteed no return of the problems that make you want to change then you can just make a fresh install including Format data. This is the officially recommended way if one intends to change build type and when you upgrade Android version (without the official OTA upgrade path).
Thanks again everybody who replied for the help ! I just upgraded, and it was much simpler than what I thought. A few remarks which may be useful for others :
I ended up upgrading with the “local update” feature. I first tried with the official build, and it wasn’t accepted from the system. I then downloaded the community build and it did the update, it took 5 minutes and caused no problem whatsoever.
I wanted to update from community to the official build because of the impossibility to do major updates with the OTA updates (i.e. going from android 14 to android 15), but if the local update allows doing just that by downloading a file, then it’s a no-brainer. I can’t relock my bootloader, which I would have liked to be able to do, but I guess I can live with this.
Well, I went for what I understood as the less risky path of updating based on the replies in this thread. I might upgrade through the PC towards the official build later on. Will update this thread if I do !
