Can i go back to Farphone OS again? (Android 10)

Yes. "Just" follow this guide: https://support.fairphone.com/hc/en-us/articles/360048050332

if you follow that guide, that I linked above, step by step, you should find the answer:

I will not answer further questions regarding this, sorry, but I am not your personal support.

Hey,
I tried to flash your build but did not success.
I downloaded your build and run fastboot flash boot halium-boot.img which resulted into fastboot: error: Couldn't parse partition size '0x'.
I have no idea where to start to fix this problem. I tried on newly flashed /e/ 0.12 but with no luck.
All I was able to do was fastboot boot halium-boot.img which for the first time resulted into successful boot but when tried again it got stuck on Fairphone logo.

Building system from scratch does not work for me (I tried commands you described and no luck there) so I am stuck for now.

Luksus

@Janez Hi, the fastboot error Couldn't parse partition size '0x' seems to be a problem of recent fastboot versions.
To go around it you should adjust the command to:

fastboot flash:raw boot bootimage.img

Janez

Thanks a lot Luksus,
now it worked at first try.
I had chance to play with phone for a while so I will try to be useful as much as I can.

SMS working both ways (sending and receiving)
Headphones work, tried 4-pin headphones, microphone not yet
Wi-Fi at home (one router) works well, in work office (several access points) oftenly disconnects

I am also still trying to connect Mullvad VPN via openvpn but did not manage to configure it right yet.

Janez

So I had some time to test the port in real scenario and here are my findings:

SMS works 100% flawlessly including messages from operator and other special numbers
WiFi works as described higher
Did manage to start openvpn through console however phone lost connection completely and went offline. After stopping openvpn everything worked
Phone calls are unreliable.
- Several times I tried and system just did not manage to make call, then it started call normally.
- Some people claimed they tried to call me but nobody answered. But phone did not show any incoming call or missed call. Log of missed calls is completely empty.
Most graphical glitches come when using camera
- Live preview is compressed to upper third of display
- Resolution is fine but noise in pictures is very high

I would really like to try to troubleshoot some of these but I have no clue how to do it so at least I am posting these issues here so someone smarter than me can focus on some of these things.

Luksus

Hi @Janez,
great that it works for you. And thanks for your help.

I can't confirm the telephony and camera bugs as you describe it. For the camera, you could try to change resolution and then switch back again.
Currently I am using another system-build (not GSI).
But I've also had some quirks here and there. Sometimes I could not stop the last phone-call, until I rebooted. Sometimes I was not able to send SMS, they also did not get displayed in history, but after a reboot, the recipient recieved all 3 SMS, I tried to sent.
I think some bugs could also be a result of the dev-build, we are using here.

I must admit that I am also not the one, who knows how to dig deeper into some issues.
I just look around and search for similar issues on similar phones and then try to apply the fix, which someone provided.

As I said above, I am currently testing another system-build, which I am using as daily driver currently. It gets build by the gitlab CI of the ubports repository.
Could you please try if it works for you, when just flash the system.img from here to your FP3?

download
boot to fastboot
then just execute: fastboot flash system system.img
reboot

What you could test here:

does it boot successfully?
does it still boot successfully, if you wipe the data partition (with twrp, or perhaps with fastboot)
- if not, does it boot again if you flash the boot.img from the gitlab CI link above
- if yes, that would be interesting

What I try to figure out here is:

If I understand it correctly, the GSI seems to boot the rootfs (ubports) from the data partition.
The CI build packaged the rootfs into the system-partition.

Normally you would either use boot.img together with system.img from the gitlab CI (option1) or use the halium-boot.img together with the GSI (option2, as you do currently).
The CI build also works, but has less working hardware yet. For example telephony only works when wifi is connected (strange thing).

I am not sure if you know how things work with a/b partitions on that/a phone.
I did flash option1 to the a-partitions and option2 to b-partitions.
Then I could switch with fastboot --set-active=a or fastboot --set-active=b between the options and compere them. The data partion is the same for both.
Then I just flashed the halium-boot.img also to option1 and looked how things work out and somehow it seems to work better than option2.
But what I not tested yet, if it perhaps just boots to the rootfs, which is placed on the data partition by the GSI.
I also would not understand why it would work better than the GSI then, because it would be the same, like booting option2.

Hm, I am not sure if it is clear, what I tried to describe...

@Luksus i works for me the last post you added.

Janez

Hi @Luksus,
I tried to boot system.img and it worked on first try, no issues. In the meantime I executed sudo apt update && sudo apt upgrade so some package versions might have been different for me on previous build.
So far I was able to send and receive few SMS messages without need of reboot.

Here are some points:

after fastboot flash system system.img phone successfully booted.
post TWRP:
- after TWRP phone did not boot
- tried to flash system.img again, did not boot
- flashed boot.img and system.img and successfully booted

After newly flashed system wifi did not appear to be working. However after reboot everything seems working. I also so far did not apply switching between two options you suggested.
Also issues I have been describing in previous post seem to be solved, in the next days I will be using this build and will refer how system works.

Luksus

@Janez Thank's for testing.

If I undrestand it right, the combination of halium-boot.img and system.img did not work for you?

And as you are currently using the CI boot.img and system.img, does telephony and cellular data connection work for you?

Nice it works now ! thanks

Hello Fred! So you were able to downgrade your FP3+ to Android 9 then install UT GSI; and Ubuntu Touch is working on FP3+?

If that is the case it's nice, it means we can develop a unique image for both FP3 and FP3+

007fred50

@oli-sax Hello,

Yes android 9 and ubuntu touch works on fairphone 3 +

do you want to flash ubuntu touch or android 9?

you can download the files here (http://people8people.com/fairphone/)

download - fairphone3_ubports.zip
there are a text file follow that

Start (wipe data) with twrp. then follow 1, the file

Janez

@Luksus yes, you understand right.

halium-boot.img and CI system.img does not boot from fresh
CI boot.img and system.img boot successfully

So far I found strange combination which works for me:

SIM card in slot 1 works and phone recognizes it. However to make phone call I need to be connected to some WiFi with internet access
SIM card in slot 2 works with and without WiFi connection
Cellular data (2G/3G/4G) does not work for me for halium-boot.img as well as CI boot.img so here I suspect wrong setup of APN. My operator did not provide me too much useful informations. I will try to work it out in next days.
