How to go back to OTA-3?

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...

@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

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

@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?
