Call for testing FP3 (also for FP3+) config for UBports-installer

Oden · 11 Aug 2021, 09:18

@keneda Thats really cool! I will look into it once I am back home. A dual boot would be a great advantage for those who are reliant on android apps.

@oden
As i don't own an a/b device i never went deep on how it works, so i would advice you to search and read about how it works and how to install, if possible on your device.

You should try to contact app dev too as he must know the how to quite perfectly.

There is high risk of messing it up, so be care

Oden · 11 Aug 2021, 10:33

@keneda Oh, absolutely. I will most likely just read about it. I just got to the point where I can use my FP3+ with UT daily and dont want to mess things up (just yet ).

As much as I am enjoying UT, I still need to use my work phone to use the Swedish ID app for a ton of things daily. A dual boot would mitigate such issues until Waydroid is fully working.

Hey there. I can confirm that the installer works quiet well But the graphics seemed to be quiet sluggish for me on my FP3.

Oden · 12 Aug 2021, 08:18

@krille Hi there! If by sluggish you mean that there are "hiccups" or screen tearing, @Luksus mentioned to me in another post somewhere here in the Fairphone3 section where he explains why. Unless you have a different issue, of course.

Krille · 17 Aug 2021, 17:37

@oden Yes thats exactly the issue. Sorry I didnt knew the correct word for the problem I have searched for screen tearing and hiccups but havent found the problem in this forum

Luksus · 31 Aug 2021, 13:25

I updated the installer config.
Now it is needed to upgrade to Android 10 before installing Ubuntu Touch. (Or the other way around: it is no longer needed to downgrade to Android 9)

I will stop to maintain the Halium9 version in the near future.

unlink2 · 31 Aug 2021, 13:57

Am I correct in assuming that with Android10 being required we can test this on a FP3+ now?

Luksus · 31 Aug 2021, 14:26

@unlink2 yes, you are right

Kjetil · 17 Sept 2021, 20:01

I just tried the installer on a FP3+ tonight, and it worked
Before my install with the UBports-installer, I had tried to install using this guide: https://forums.ubports.com/topic/5373/fairphone-3-fp3-port
That was not successful, and left the phone without any working OS. In this state, I tried the new Ubports-installer, and all my troubles was gone ! Great work ! Thanks !

Luksus · 17 Sept 2021, 22:14

@kjetil great that it works now.
I assume, you did forget to flash the android 9 vendor image before?

Kjetil · 18 Sept 2021, 09:21

@luksus You are right: no flashing. I booted the vendor image to put the device in developer mode. Then I tried to install without the UBports-installer, but failed. The phone would not boot any image. Finally I tried the UBports-installer, and it installed, and worked !

@kjetil Hello,
for me the ubports installer worked, too! Kudos to you guys.

Hi,

I am new to smartphones, tested the installer (version 0.8.9 on Ubuntu 18.04) with the Fairphone 3 (not 3+) and I got this error:

Error: adb:preparesystemimage: Error: {"error":{"code":1,"cmd":"adb -P 5037 shell mkdir -p /cache/recovery"},"stderr":"mkdir: '/cache/recovery': Required key not available"}

I reported the bug here: https://github.com/ubports/ubports-installer/issues/2155

I followed all instructions. Bootloader was unlocked, developer mode enabled, USB on debugging and file transfer. If I ignore the error, the installer shows success but the phone stays in Ubport Recovery and I can not boot Ubuntu Touch at all. I can reproduce the error, just installed /e/ now to have a break (since my old phone is broken).

I am interested but probably rather user than developer. But I switched to smartphones very late (due to all this OS mess) and had one year sailfish OS now. I chose FP3 to get ubuntu touch and really, really want it to work...

If you have any ideas, please let me know.

@strangeli

Hi,

difficult to help you precisely.
But there are a few stuffs to explore:

Check your USB-C cable and try with another USB port. (preferably USB 2.0)
Check that you have the adb and fastboot packages on your computer:

sudo apt-get install adb
sudo apt-get install fastboot

Check that your PC has access to your device in fastboot mode:

fastboot oem unlock

In principle, the device must be in Android 9 version, because of the compatibility of firmwares. So you have to downgrade to an Android 9 version (or LineageOS 16 or /e/OS Android 9)
You can try to get the ISO of Ubuntu 20.04.3 and run it in a live USB session and then try to install it on Focal (I assume that the installer is configured for 20.04 and later)

Hopefully these hints will help you. If not you can also ask for help on the Telegram thread:

Hopefully these tips will help you. I wish you success in your installation.

strangeli · 1 Oct 2021, 01:15

@stanwood

Ok, thank you, I will try soonish. I first asked in the telegram group and they referred me to this forum.

adb and fastboot was installed correctly and since I had no problem entering UBports recovery mode or flashing /e/, there should be access to the device. I thought I read that the installer is for Ubuntu 18.04+ and that I can depart from Android 10 but maybe it's worth trying from 20.04 and Android 9 then. I will check, thanks.

Good to have the live stick anyway for upgrading my laptop ;-), was next on the list.

Luksus · 1 Oct 2021, 08:54

@strangeli @stanwood :
Downgrading to Android 9 is not any longer needed.
The phone should run with Android 10.

@strangeli: I don't remember if I gave you the advice already (edit: there was another user at the fairphone community forum), but did you choose the option "wipe" in the installer?

It sounds like the cache/userdata is still encrypted.

Also, it seems necessary, that the device is running a fairphone android version, before installing UT.
On my initial tests, it did not work with a previously installed eOS version.

rikisorsa · 1 Oct 2021, 15:26

I have lineageos android 11 on my FP3, can I install Ubuntu Touch on this or should I install normal fairphone android 10 before?

Keneda · 1 Oct 2021, 17:08

@rikisorsa
From what said @Luksus previously, i'd install FP OS 10 first.

Luksus · 1 Oct 2021, 17:15

@rikisorsa yes, please install fairphone android 10 version first. I have no experience with LOS 18.1, but even a previous installed LOS 17.1 did not work for me.
