I've used LineageOS with microG on my Oneplus 6 for years โ€” so happily, in fact, that I haven't bothered with major updates since version 17 (Android 10). Oops!

Now I've been flashing updates to an older phone, and I might as well continue getting my daily driver up to date. I'm going to dirty flash my way up to the current version (21). But I'm rusty as all heck, and the upgrade instructions seem to have changed since last:

  1. Back in '21 I recall being recommended to disable screenlock (fingerprint/PIN/pattern, etc) before upgrading. Is that still a thing?
  2. With a/b slot devices it used to be necessary to flash ROMs twice or use a copy-partitions or simiilar zip file. The instructions make no mention of it, is that rolled into the upgrade package now?
  3. Finally, is it safe to just upgrade directly from LOS/mG v18 to v21? Because neither LOS main or the mG branch seem to archive older versions but I'd hate to miss some system update or other.

All help is appreciated!

Edited for clarity: Please don't offer suggestions on "better" phones or OSes โ€” my question regards the above only. Thanks in advance ๐Ÿ‘

I dont think that release message has anything to do with that

I dont know how Android does updates. The current system slot is read-only. It may be that the first system update reads from that slot and writes it to the other partition, then downloads the diffs, apply them here, then reboot.

But it may be that the signing keys have changed etc. In general, Android 10 to 14 is a huge step and this can likely cause breakages. Just please flash both slots.


From that point of the OS updatr on I have no idea what is GrapheneOS and what is AOSP.

On GrapheneOS you do a reboot, on an early boot screen your apps are updated too, I think they are in part precompiled and this is then done for the new base OS.

Then after the reboot, there are still optimizations going on in the background, if you press a button all these apps are killed to be reloaded with the new dependencies.

Please, enough with GrapheneOS. I'm not interested. This insistent return to an OS I haven't asked about is off topic and irrelevant. You do you, but this is way off the mark from my question.

ETA: by now you've stated that "Android does updates by downloading the diff" etc, but also that you "dont know how Android does updates". I dunno, maybe don't pretend to offer help if you can't keep your story straight. Next caller, please.

I just told you how GrapheneOS, which is basically AOSP, does updates.

Maybe ask in an actual LineageOS support forum :)
