How to go back to OTA-3?

[advocatux]

@lyovushka thank you

[lyovushka]

@krille For me GPS worked after a fresh install (with wipe) and then stopped working after the first restart. I am back to OTA-3 now and GPS works again. Hopefully GPS and media player will work in OTA-6.

[Krille]

At the trip in Vienna GPS always broke again after some time. You were right. I'm now switched to the rc channel and there it seems to work so far...

@lyovushka

How did you hack the ubports-installer to install OTA3 ?

[mprotic]

This works for rollback to OTA3:

ubuntu-device-flash --server=http://system-image.ubports.com touch --device=arale --channel=15.04/stable --revision=3

@advocatux said in How to go back to OTA-3?:

What happens if you run this in your phone terminal? sudo system-image-cli --switch 15.04/stable

Today I tried to downgrade back to 15.04... Didn't work. The device was a clean install.

Just reffering...

[advocatux]

@jezek have you tried forcing the UT version with that command @mprotic posted?

If you don't have ubuntu-device-flash installed in your computer [*] you can install Ubuntu 16.04 in a usb stick and install in it all the necessary tools too (ubports-installer, adb, and fastboot).

[*] Assuming you don't have xenial running in your computer

Edit: of course, don't forget to change "arale" for "FP2" in your case

[jezek]

Strange. On my notbook, I have adb, fastboot and even ubports-installer installed, but the ubunt-device-flash command is missing. How can I install it?

edit: notebook is a

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.1 LTS
Release:	18.04
Codename:	bionic

[advocatux]

@jezek it's only available for trusty & xenial. If you're running anyone of them, you can install ubuntu-device-flash (you forgot an 'u' btw) enabling the "universe" repo.

Edit: ah, you edited your post. Use a live usb stick then or try to run that package (https://packages.ubuntu.com/xenial/ubuntu-device-flash) on your computer but I don't know if it will work.

Another edit: Thinking about that now, I think someone (maybe @dobey?) built that tool for 18.04.

[jezek]

@advocatux Sorry, where did I forgot an 'u'?

[advocatux]

@jezek in ubunt-device-flash. I pointed at that just in case you were typing the wrong command

[jezek]

@advocatux ahh... I see... just a typo on this forum... in terminal I tried the right thing...

[advocatux]

@jezek I've found that tool built for your OS

https://repo.ubports.com/pool/bionic/main/g/goget-ubuntu-touch/ubuntu-device-flash_0.35+ubports+0~20181003134221.2~1.gbp4044a0_amd64.deb

I have to sort out the dependency stuff somehow... anyway thank you

[advocatux]

@jezek you're welcome. I'm pinging Rodney now, he built that package and he knows the solution for sure

[Stefano]

@advocatux it won't install on mine 18.04, it shows installing, shows 100 %, and then nothing. How's that?

[dobey]

@jezek You should be able to run sudo apt-get -f install after manually installing a package with dpkg, to resolve the dependencies. If any are uninstallable though, I think it will just remove the package you were trying to install. I'm not sure if all of those dependencies are available in Ubuntu 18.04 though.

All I did was fix the build so goget-ubuntu-touch would build on bionic. If it's not working/installing, feel free to open an issue or two on https://github.com/ubports/goget-ubuntu-touch about it.

[jezek]

Meantime I tried to downgrade via ubports-installer
Selected 15.04/stable, choose wipe option (for sure) and followed the instructions... result was, that 16.04/stable was installed...

To summarize: It is NOT possible to downgrade to 15.04 either with ubports-installer, nor with system-image-cli. And on 18.04 I failed to install ubuntu-device-flash tool, so there is no way to downgrade to me for now.

I will not accept defeat, will try again. Any suggestions?

Btw, the phone is FP2.

[jezek]

@lyovushka Please, help me. How did you hack the ubports-installer to install 15.04/stable - OTA3?

[jezek]

@dobey How did you build the goget-ubuntu-touch

I have tried to clone the repository and followed the README.md, but it was a dead end.

Then I used the go get -v -u github.com/ubports/goget-ubuntu-touch/ubuntu-device-flash command... result

so I have fixed all imports in .go files from launchpad.net to github.com/ubports and managed to build the ubuntu-image-flash binary and ran it. But with no success:

$ ubuntu-device-flash --server=http://system-image.ubports.com touch --device=FP2 --channel=15.04/stable --revision=3
Unknown command `ubuntu-device-flash'. Please specify one command of: core, personal, query or touch

any suggetions?
