Lineage 18.1 - finally official

[chrmhoffmann]

I would try to install official FPOS and see if it’s a hw defect.

Ah, thanks for coming back to this. In FP-OS there is nothing reported like this, only LOS?

Hi,
I have experienced the same issue under Lineage, /e/ and FPopenOS. There were some differences, but it was basically the same issue. Under one of the OS (don’t remember if it was /e/ or Lineage), I had more frequent reboots, but under others, the app freezes instead and I can get to the home screen and use other apps without problems. Then after 1-2 minutes, I get an error message saying that the frozen app doesn’t react, so I can close it and reopen it.

I am using FPopenOS right now and have been for a year I guess. I wanted to give Lineage another try as it is the OS that I liked the most and had been using the most before the issues, but I have been too lazy to do it…

Hi,

Glad you’ve had some success FPopenOS. That’s good to hear. I abandoned my FP2 for an FP3, but now I’ll give it a try again .

For reference, here’s an old topic where we discussed this previously. Don’t think there was any solution, other than getting a new core module:

Strange screen issue

Last week I broke and replaced my FP2 screen (here the full story). The new screen is working fine, but I have a strange issue happening that I never had before. From time to time (I am looking for a pattern but I have not found one yet), my screen gets all blurred and dotted (see pictures), it stays like this for a couple of seconds and then goes back to normal. It is not a huge issue, it is just an unexpected behavior, but I would like to solve it and, especially, to know if it is a symptom…

Does anybody know why we do not get a new build since 14.01.2022?

Thanks for this topic reference, was of great help and describes exactly my current proplem. Now I changed in developer settings the “Animationsdauerfaktor” (animation duration factor?) from 1.0 → disabled - and until now all the apps with animations which triggered before a crash doing this not anymore. Instead of the animation just a arrow is displayd - looks ugly, but functionality is not limited in my view and it doesn’t crash.
So I will try to keeping FP2 alive with this a little bit longer … 6 years and counting …

Seeing the 3.6.0 TWRP update now supports Android 11, should I understand that if this version was ported to the FP2, TWRP would be compatible again with Lineage? @z3ntu, do you intend to port it?

[z3ntu]

There was a build failure but it’s available now: Download TWRP for FP2

[Alex.A]

Thanks! We just have to know if it fixes the incompatibility now. @chrmhoffmann would you be able to tell?

I just struggled a bit getting Magisk installed after flashing LOS 18.1. Is there already a main wiki post / detailed guide about install Magisk on fairphones?

I basically followed the
Magisk install doc:

Installation

I tried both

1. the “adb sideload a Magisk zip” - way (mentioned as depricated)
2. the "patch boot.img and fastboot flash boot /path/to/magisk_patched.img " - way

but I always ended up, that the FP2 does not boot anymore (stays in the first “FAIRPHONE POWERED BY android” welcome screen).

Any idea/suggestion/idea what I’m doing wrong? Maybe is Magisk 24.2 not really working for the FP2 yet? (will give it another try with 24.1 now - not sure how I get to the point to already use 24.2 EDIT: was marked as suggested in Izzy-Droids Repo … - seems to be still a beta right now ‘2022-03-07T23:00:00Z’ → GitHub - topjohnwu/Magisk at v24.1
)

EDIT: 24.1 works …

Regarding docs/wiki note:
I just found this for the FP2, but only with links and no real details. How to root my FP2 with LineageOS 17
A wiki note might also show the differences for the FP3 and FP4 (maybe the boot.img approach works or is needed there) or just link to existing other docs (maybe there are already dedicated threads or wiki entrys for the FP3 and FP4). For the second way (patching a boot.img) I think it might also worth to mention where to get the boot.img (Magisk install doc does not really say something about it)? I assume extracting it from your rom’s build zip which you plan to install, right?

Also a point which can be mentioned - a recommended moment when to setup Magisk? Directly after the LOS flash or boot the OS ones and e.g. set up encryption and then setup Magisk…

[yvmuell]

maybe this recent discussion in german helps. 🇩🇪 Lineage 18.1 rooten

there was a how to that is obsolete in my eyes as Magisk recently changed “a lot”. For FP4 we have a good guide on how to root with Magisk, don’t know about FP3 havent searched for it.

[Smojo]

Thanks. Also not that on point but hints like:

Übrigens ist die “alte” Methode (= Magisk.zip via TWRP zu flashen) bei mir die, die am zuverlässigsten funktioniert hat.

Should be part of the wiki note and as explained maybe just link the other descriptions/guides for the other fairphones (and do not double the info). I think about some kind of “master-note”.

Maybe I will prepare something as soon I my phone is set up again

I updated my post above and the “sideload zip” way (nr. 1) worked fine with Magisk 24.1

[yvmuell]

This here is the LOS thread, nothing Magisk specific and when you feel something is not up to date, then either rewrite thewiki, or if the topic is no wiki, then yes write a wiki or I can make the topic a wiki for you to update?

Edit:I see you should be able to open the old topic and make it a wiki on your own😉

@Smojo

Magisk.zip via TWRP zu flashen

I confirm that this method always worked for me on FP2

[yvmuell]

Should the TWRP method ever stop working as its no longer really maintained, this is a statement for FP4 but assume is true for FP2 and LOS as well

“The current stock boot images for FPOS can always be found on the kernel page, the /e/ ones can be taken from their released zips”

[Smojo]

@yvmuell

“The current stock boot images for FPOS can always be found on the kernel page, the /e/ ones can be taken from their released zips”

Thanks for this little add. This was, what I wanted to know. For Magisk 24.2 I can tell it does not work with a patched Magisk boot.img. I took one from FP Open’s zip as wall as one in the latest LOS Zip → no success in both cases. As the old (sideload zip) way worked for Magisk 24.1, I did not try the patch boot image way again with this Magisk version.

Regarding TWRP:
I was always a TWRP user, but this time (as I read some difficulties - probably only regarding encryption) I used the LOS Recovery.
At the end I mostly used the wipe possibilities and adb sideload and this is possible with LOS Recovery as well.

[oli.sax]

@Smojo

as I read some difficulties - probably only regarding encryption

TWRP always had difficulties with encryption on FP2, but for this release of LOS (18.1), TWRP has also difficulties with the LOS OTA updates: the two times I tried I got a not-booting device after performing a Lineage OTA update

[yvmuell]

I assume there are good reasons for the initial statement about TWRP😉

@chrmhoffmann

Flash the Lineage recovery: TWRP is not supported right now.

And you did a quite dirty installation, not recommended

[oli.sax]

@yvmuell

I assume there are good reasons for the initial statement about TWRP😉

I agree!
But I’m a researcher and I like to experiment by myself

BTW I noticed that dirty installation (migration LOS 17->18) is not a problem with TWRP.
The issue came only with OTA-updates, both on the dirty installation and on a fresh-installed LOS 18.1

I usually only update my phone if the Android security string was bumped again, so I did that the day before yesterday. Today I wanted to use Osmand which usually has its maps installed on the SD card. Now it fails to do anything with the SD card. It cannot list the available space, it cannot find the maps, I even extracted the Osmand directory from Android/data/ and moved it to the root directory of the SD card to have it out of the sensitive area. If I tell Osmand to use this new directory it tells me that it cannot create maps in that directory.
I’ve looked through the changelog of LOS and found this one:
https://review.lineageos.org/c/LineageOS/android_packages_providers_MediaProvider/+/328228/
Could that be related to the issue I’m seeing? Does anyone know how I could fix this? For a quick workaround I could put the maps that I currently need into the internal storage, but usually I have more maps than what the internal memory permits…

Thanks,
Martin
