Lineage 18.1 - finally official

@chrmhoffmann : Thank you very much for your many years of continued work on Lineage for the FP2! For me, this has been a critical factor to achieve the objective of a phone that stays alive as long as (reasonably) possible and, thus, contribute to a (more) sustainable environment.

Regarding compatibility between LOS 18.1 and TWRP: Does the need to work on this currently lie with Lineage or with TWRP? Both? Or Unspecified?
And could you tell if it’s being actively worked on right now?

(Reason why I’m asking: I’ve used TWRP quite often, for a long time and rather liked it. So I try to estimate how likely it is that it will return…)


If its not coming soon you can still use for back ups #twrpwoflashing

Edit 23Nov21: tried to restore a back-up on another device without success, ended up in a bootloop.

Not sure if that is still valid…

My statement? At least I used it to create a back-up

I have no plans to work on this. I don’t know if someone is going to pick it up.

Hi, when I try to flash LOS recovery and reboot into recovery I’ll get the Android “no command” screen. When holding power button + pressing volume up at this screen again I’ll end up at Android recovery.

I tried the official procedure and I tried to flash the LOS recovery using TWRP (without flashing it), same result.

I checked sha256 and also tried another build of the LOS recovery, same result.

The Phone currently runs Andoird 7.1.2

I bought the phone second hand and the previous owner said she did a factory reset.

Any hints?

Do you directly after installing/flashing the LOS recovery, reboot into the recovery? Booting first into system will overwrite with FP recovery.

Yesterday I switched to LineageOS 18.1 for microG and I know this is for the official one without microG, but they share a large amount of code and I hope to get some help :).

@chrmhoffmann Are you aware of any VPN issues with LOS 18.1? With 17.1 I was able to connect from my FP2 to my FRITZ!Box just fine. This is currently NOT working with LOS 18.1. Any ideas or recent fixes that are not yet integrated in the microG version (which is at 2021-09-15 currently)?


I just checked again with LOS 18.1 and GApps pico and for me VPN works with my Fritzbox 7362 SL. As far as I can tell this has always worked with LOS 18.1 (but I don’t use it regularly).

Maybe you could share more info about the setup. Maybe there is something in particular that Singulus is using that is broken.

FRITZ!Box 7590 with latest FRITZ!OS, but I can share a workaround, which fixed the connection problems (in german sorry):

It seems that my carriers APN settings (Telekom) needs to be switched to IPv4 in APN-protocol, they were on hybrid-mode IPv4/IPv6. Any ideas if this “fix” should be integrated into LOS?

Yes, I’m sure that I directly booted into recovery after flashing, at least several times.

Any other ideas?

I think I would try to flash TWRP permanent, just to see what happens and/or try last LOS 17.1 build with LOS recovery and then when it works 18.1 afterwards and/or upgrade to FPOS latest Build, therefore you might need to update the updated App first….

It’s not available anymore.

Hmmm… I have the LOS build but not the recovery however as its TWRP compatible could be flashed using TWRP

Same, I kept about a 17.1 LOS build a month for the last year if someone needs.

Hi, thank you for all the work and the instructions.
It is, however, not quite working for me.
I did flash the lineage recovery as instructed, did the data wipe and installed lineage 18.1 via adb sideload.
There was no error message, but it seems to get stuck upon booting. It reboots into the lineage recovery, telling me to wipe/format my data again, which leads to again getting stuck in booting.
I don’t know what could be the problem, as I don’t get any error messages and the adb sideload tells me that the installation finished.
Tried with and without OpenGApps and with different versions of lineage 18.1, but get always the same result: super long boot and reboot into lineage recovery.

it seems to be a problem with the version of openGapps: 20210929. was reported for multiple devices on reddit.
the installation works with the version 20210925.


Did anyone try to encrypt their FP2? @chrmhoffmann I get the error Cryptfs : Orig filesystem overlaps crypto footer region. Cannot encrypt in place. I found some comments on this in the forum about resizing data partition, but is there any current documentation what are the most recent and correct stepts/values to do this?


@yvmuell you were right. Looks like I didn’t boot into recovery directly after flashing the LOS recovery. I tried again directly after flashing and used power button + vol up to boot into recovery and it worked.
I think I used shell commands before to boot into recovery.

Thank you very much for the hint and sorry for my mistake here. I must say it was not clear to me how to do it correctly, neither after reading LOS installation guide nor after your post. My bad, but maybe it might help others to be more specific in this case :slight_smile:
