FP4 and LineageOS

I mean it dose look like fairphone has put work into porting lineageOS but I doubt it is the top of their list when launching a new phone

An economic interest. /e/ is trying to make money and has employees who work on the port full-time I assume. LOS being developed purely by enthusiasts atm.


Fairphone is not putting work into porting LOS this is still a community effort done by samwein, dk1978 and others, as indicated in this thread


My bad, yeah… I should have checked that… just threw me it being in fairphone repo

It’s not the Fairphone repo. It’s the WeAreFairphone repo. WeAreFairphone is a term used by the FP community to describe itself.


It looks like the Murena Fairphone 4 from the /e/ people started to ship today. Have they already released the source code of the android version that shipped with the phones? I couldn’t find it on their gitlab and although LineageOS’s Apache license allows for proprietary derivatives, they do claim /e/os is open-source so it’s probably in their interest to publish their changes.


Hi all, Quick question.

I have just received my new FP4.
I currently run LineageOS on another phone, so I would like to run LineageOS on the FP4 too.
I see messages that LineageOS is still in the works, some messages mentioning half to end of January.
Does anybody have a rough idea when Lineage OS will be available for the FP4? I do not need an exact date, but a rough estimate would be nice. Are we talking about weeks, months or longer?
(I am in no hurry, so I do can wait for some time if needed)

In a few weeks or so…maybe.
Nobody know it, actually

Hi Hulk, (is this because you bought the green model of the FP ? :slight_smile: )

OK, I can live with that. Thx!

It seems /e/ sources are now published: e / devices / Fairphone 4 / android_device_fairphone_FP4 · GitLab


And also /e/ ROM :wink:


U can use iodeOS

6 posts were merged into an existing topic: FP4 - Rollout of the very privacy-friendly custom ROM iodéOS has started as Beta

We are working on it. You can already compile LineageOS for FP4 yourself if you have a device to pull blobs from:


Hi! first thank you for the hard work.

Could you provide a quick status on device support completion ? (ie. what works / doesn’t work, any known quirks, what’s left to do, anything you’d need help for…)

I’ve been eagerly watching your repo for a few weeks, but before taking the time to try my own build, I’d like to know if it can produce something in a usable state for me at this point.

btw, are there any special build instructions besides what can be found on LOS’s wiki ?
do you have another communication channel besides this forum to discuss LOS development on FP4 ? (most other devices have dedicated sections on xda forums, but I can’t find anything about FP4 there, except a few general threads from people asking the same questions…)


I have managed to build it myself and @Aaanze seems to be running it on his Fairphone 4. You can read more about how we figured out how to build it here and here.


oh great thanks! did someone actually try to install it ? :smiley:

Yes, I’m running it currently…
So far I did not notice any issue, it’s pretty smooth.
Only thing is for some reason (apparently system partition too small), I wasn’t able to flash openGapps, so if you count on using Google services, think twice before flashing it as there is no way back for now.
I will try to make another build with pico Gapps bundled and see how it goes.


That’s great news.
Would it be possible for you to share your ROM?
I don’t mind the no-Gapps restriction, not wanting anything to do with google is precisely the reason why I’m refusing to even use my FP4 with stock android.

Sure why not.
You will flash this at your own risk though :smiley:

You will need:


1. Reboot to bootloader

adb reboot bootloader

2. Flash Lineage recovery:

fastboot flash recovery recovery.img

3. Reboot to recovery.
If stock recovery boots instead (happened to me at first) just go back to bootloader and run:

fastboot boot recovery.img

4. In recovery: wipe data / Factory Reset - there’s no way back to FPOS (for now) after this

5. Still in recovery: Apply Update → ADB Sideload → Install from ADB and run:

adb sideload name_of_the_lineage_file.zip

6. Attempting to flash GApps will probably fail due to lack of space on system partition (although nothing prevents you from trying if you want to give a shot, please report if it worked)

7. Do not flash Magisk as it will throw you into a bootloop. You will be able to root the old way later like this:

a. Downloading boot.img on your device
b. Installing Magisk apk
c. Patch the boot.img with Magisk
d. Copy the patched file on your computer
e. Reboot fastboot and fastboot boot your_patched_boot.img
f. Open Magisk and run installation
g. Reboot

8. I “THINK” you should reboot bootloader before boot and run (untested):

fastboot erase metadata

I didn’t do it and have a “E: couldn’t mount metadata” error everytime I try to flash something in recovery, though it doesn’t prevent lineage installation.
It appears to be the last instruction in /e/ OS installation procedure.
If you run this command please report :blush:

That’s about it. I only ever built 2 ROMS and they are both iterations of this very one which gives you an idea of my level of expertise. Bottom line: don’t expect high end support (I’ll do my best though). I find myself constantly asking for help around here :smiley:
