Prevent update
-
@lakotaubp No, it's a Nexus 5. Apologies, I mentioned that fact in the previous post but should have repeated it here.
-
UT version should look like this :
With OTA-17 now intstead of 15. -
@cliffcoggin Have you tried just rerunning through the installer (without wipe) to get stable back on. Or are you having issues with that too?
-
Switching channel can indeed be wonky and sometimes show you multiple updates if you switched channel multiple times. I suggest to just try switching to stable again and wait for the update to show in the updates page. If still nothing, try restarting settings app and/or go to
About > Check for updates. -
@kugiigi That's the heart of the problem. Trying to downgrade from Development or RC does not prompt an update to begin.
-
@lakotaubp My reluctance to re-install stems from a bad experience a year ago when I found it impossible to install UT on OP1, which led me to get rid of the phone. I don't want to do the same with this Nexus 5 and ruin it.
-
@cliffcoggin As you already have UT on this one it should not really be an issue as long as you don't select the wipe option. But the choice is yours at the end of the day and maybe save it as a last resort when all else has been tried.

@cliffcoggin
I switched from RC 101 or 102 to Stable on my Nexus 5.
No real problem at that time.
After setting the Stable channel, go back then close and restart the system settings.
And check that the channel is still set on stable.
Sometimes you just need patience to get the download.Oh and network coverage should be good.
I do this at home with wifi and close to the router, not too far where I have weak points. -
@applee Restarting System Settings after setting to Stable caused an update to show. The "update" lasted only one second before showing that software is up to date, which is far too short a time for anything to have happened. Going back to System Settings from there showed 1 update available again, and so on in a cycle that repeated endlessly. I gave up after 6 such cycles, turned the phone off, then restarted it. I am back where I started on Development.
I am convinced that the update is not downloading or installing. Upgrading works; downgrading does not. If re-installation is the only solution it will have to wait for ten days until after an imminent holiday as I dare not risk losing use of the phone while away from home.

@cliffcoggin
My bet is more about the channel not really changing internally.
If when you reopen the system settings you still have the stable channel selected that's a first step.I think something like for the hotspot setting something might be funky with switching channels.
Best of luck.

Some progress. After an update to Development version 2088 today I could downgrade to RC version 103, which all worked as expected in that a 427 MB update visibly downloaded, then installed itself without intervention from me. I have no idea what has altered to allow me to change channel today. I shall leave it a day and restart a few times before attempting to downgrade to Stable.
-
For what it's worth, I had similar difficulty in moving from Halium Devel to Stable recently. It would look like the change was made, but it just wasn't. I kept trying and eventually it stuck.
-
@moem Thank you for confirming that I am not unique in downgrading problems. I was beginning to wonder if I had completely lost the plot.
-
@cliffcoggin If you have, then we both have. I wish I could tell you what I did to make it work. But it was so unremarkable that I don't really know. Some combination of reboots (from complete power down) and keeping on trying.
-
Maybe channel switching must be improved. Displaying/downloading/installing the actual update within the switch channel page may help avoid confusions.
-
@kugiigi On my OP5 when you change channel you do get the spinning wheel to confirm channel change then the tick appears by the 'new' channel (Channel Settings). The next page back though (Update Settings) shows the 'old' channel until you go back one more page to Updates and the download has started then the channel on Update Settings changes. So there is a slight 'slight has it worked' moment that could be a bit clearer that things are working.
How this could be done and at what stage and by what the changes are indicated I don't know. Sounds like a potential design question to me. Good idea though.
@cliffcoggin I get this every so often too. So you are most certainly not alone
If a few switches back and forth don't fixit I do resort to the installer. Patience is not a virtue I always have. -
@lakotaubp Yeah wes hould update the list when we go back through the pages, its highly confusing since years
-
@flohack Is it known why downgrading is such a widespread problem, and are there plans to overcome it?
-
@cliffcoggin In general I do not suffer from problems when I am downgrading, lets ignore the visual detail for the moment.
What you should do: Before changing channels you should install any pending update. Chances are high that your device downloaded a nightly update when you are in devel. If you dont install that, but switch to stable immediately it can become stuck in some way. Thats the thing I would always do, install all pending updates before changing channels, even if it takes much longer.
Well plans for fixing it: We have so much to do its nothing that has an ETA yet.
-
@flohack Thank you. By chance I had a Development update immediately before downgrading to RC. I wondered at the time if they were related.
