How to go back to OTA-3?

[advocatux]

@arubislander if you run system-image-cli --list-channels it lists the available channels, including aliases.

At what level is the redirection working? Is it too deep (so to speak)?

You can see all the options for that command here http://manpages.ubuntu.com/manpages/xenial/man1/system-image-cli.1.html if you want to give it a try to force a specific version.

Edit: hmm maybe I'm too tired now but I'm been seeing the "hidden redirects" and I still don't see the full picture clearly (there are some typos btw). I'll give it another try tomorrow

Edit 2: if that system-image-cli command doesn't work for you, and you have ubuntu-device-flash installed in your computer, you can try that way too.

There is a reference to both OTA-5 and 16.04

[lyovushka]

OK, I hacked ubports-installer to install version 3, rather than the latest version and it installed OTA-3 for me.

[Krille]

@lyovushka Hey the problem with GPS was on my Nexus 5 too after the Upgrade to OTA-5. It is gone after a reboot. Have you tried this?

[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...

[mprotic]

@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

[jezek]

@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?
