How to go back to OTA-3?

[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

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?

[dobey]

I just tweaked a few things to get the debian package building in CI. I didn't actually build it locally.

I didn't run it either. I just presumed if it built, it would work.

You can however, grab the ubuntu-device-flash package from the official Ubuntu 16.04 repositories, and it does indeed run and work on 18.04. I'm not sure why the build in the ubports repo would not work. It seems there may be some additional issues there.

[advocatux]

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

@jezek my suggestion still is: use a live usb stick running xenial & the necessary tools

[jezek]

So, after I dug out my old netbook from the dust of my stash shelf, which was already equipped with lubuntu 14.04, I successfully installed ubuntu-device-flash utility via apt package manager, and used the utility to downgrade to 15.04.

Wish, this can be this easy on bionic (18.04).

I will look into the ubuntu-device-flash utility on ubports github and try to make it work.
