Official LineageOS 19 for Fairphone 3/3+

[lklaus]

Hi Achim.
No not with zram active. I had it with magicearth earlier, but i did not see this for a long time now…
I don’t think the cwa does a lot, most of background processing happens in the Google part (or microg if using the f-droid version).

I think that systemui is a los (resp android (thing, not gapps, for the rest that’s way over my head

I just wanted to link to the lineage 20 unofficial build:

[ROM][UNOFFICIAL] Unofficial LineageOS 20 for Fairphone 3/Fairphone 3+

As always, my sincere thanks to your overwhelming response to [ROM][UNOFFICIAL] Unofficial LineageOS 19.0 for Fairphone 3/Fairphone 3+. On this positive note, I present to you the first build of LineageOS 20 running Android 13 for Fairphone 3/ Fairphone 3+. It’s coming earlier than expected because Android 13 was simpler than Android 12. If you would like to express your thanks to me by means of hard currency, please visit my Ko-Fi page: TeamB58 .

It was of course created by teamb58. Thank you!

Hi all,

I’m having some trouble flashing the LineageOS with microg.

I unlocked the bootloader. Flashed the lineage recovery, sideload LineageOS.
All worked well. But then, I needed to install some system app (Aurora services). Is there a way to do it using Lineage recovery ?
I tried to flash TWRP instead of Lineage recovery but it seems that after that, when i lock the bootloader, I can’t boot my phone anymore ?

So, what is the best way to do things ?

• Letting the bootloader unlocked (but find a way to remove the anoying warning) ?
• Finding a way to install system app and even root if I want (not sure about that) using Lineage recovery ?
• Finding a way to have TWRP AND a locked bootloader ?

I’m kind of stuck on this one, can’t find what to do.

Thanks

Flashing TWRP is not the best idea. If you need it permanently instead of just booting into it, I would advice to look at the official instructions on how to do it

Fairphone 3

[Kendoulou]

Thanks for the idea.

But from what I understand, I need the bootloader to be unlocked in order to boot TWRP.
So if I boot to TWRP, install system app and then lock the bootloader, it will wipe all my data (including the system app I installed).

Is there something I’m missing there ?

[mll]

I used to systematically use TWRP on my previous phones, but on my Fairphones, I see some weird behaviours (probably due to my lack of knowledge on what’s happening on these low-level systems), so I finally sticked to the tutorials and used LOS’ recovery.

And I never relock the bootloader. Maybe there are ways to hide the annoying warning, but I learned to live with it.

[Kendoulou]

And are you able to install system app with LOS recovery?

[Switch]

What I would do is:

1. Unlock bootloader
2. Install Magisk
3. install Aurora service magisk module
4. use zygisk to hide root/unlocked bl if needed

[yvmuell]

Just to add: you cant have a rooted phone with a locked bootloader

[mll]

If you mean Magisk, then yes, definitely.
I also recently installed MindTheGapps on a Fairphone with LOAS recovery.

[Kendoulou]

Thanks for all the ideas.
I’ll try some stuff this evening.

Quick questions :

• from what I read, to install magisks you need to patch the ROM. Installing through recovery is deprecated. Does it still work ? If I use the patch ROM method, what happen when I update the ROM ? Will it remove magisks ?
• also I’m a bit confused about locked bootloader . when it’s locked ,does it only prevent from booting / flashing recovery ? Or it also prevents installing things from lineage recovery (which works even when bootloader is lock after flag) ?

[Kendoulou]

OK so I dig into the internet and found the answer I needed.

• magisks and ota update : can be done but you have to update "manually " following these instructions : OTA Upgrade Guides | Magisk

• for bootloader, I read that having a locked one doesn’t prevent you from installing from recovery. But it doesn’t seems to be useful to lock the bootloader. Good post I found : https://www.reddit.com/r/LineageOS/comments/n7yo7u/a_discussion_about_bootloader_lockingunlocking/

I guess I’ll try a lineage + magisks setup and just live with the unlock bootloader warning!

Thanks for the answers!

My experience: the patch ROM method didn’t work for me. But the installation through recovery (rename the apk to zip, sideload on recovery mode) always worked for me.

[Kendoulou]

Patch ROM method worked for me. I patched the lineage microg boot img.
I didn’t find the vbmeta.img so I didn’t patch it. I had a bootloop at first but a factory reset was enough to fix it.

Thanks again for the support !

Hi,
does anyone besides me also have the issue that the latest LOS update (06.03.2023) is installed but is not active after installation and a reboot? It seems the wrong partition is active or something else goes wrong.

EDIT:
It works now as expected. I downloaded the Update a 2nd time, installed, reboot and now it is installed.

Here the link to the 20.0-release:
