Re: Nexus 7 won't boot

 

Finally solved this one. Reinstalled Android, enabled debugging, rebooted via adb into bootloader, and ran the ubuntu install again.

Cheers,

Mitchell

Ok, so still having some major issues with this here - not sure what's wrong. Have now successfully flashed rtm-proposed, utopic-proposed, and vivid-proposed, non of which will boot past the Google icon. Have tried wiping the cache on all images, have aso tried doing a factory reset to wipe the data in the recovery. Still no luck. Have also tried letting the Google boot icon sit there for a half hour, still no luck.

Has anyone gotten a Nexus 7 to boot recently from bootstrap? Have just updated everything on my install of 14.10, and am now trying on my wife's 14.04 laptop to see if that makes any difference. Next step will be to totally reinstall android, and try again from scratch. Tedious...

I'd appreciate anyone's advice about getting this to work, or to tell me how to debug this so we can figure out what's going on. Will post back if I find anything useful.

Flashing a Nexus 7 2013 (flo) with rtm-proposed won't boot, version 109. Device hangs at Google logo. Same behaviour from vivid-proposed, version 1. I seem unable to download the archive from the stable (rtm version 5)
to flash. Here are the commands I've tried:

ubuntu-device-flash --channel=ubuntu-touch/ubuntu-rtm/devel --bootstrap
&
ubuntu-device-flash --channel=ubuntu-touch/ubuntu-rtm/stable --bootstrap

I keep getting the error: "Failed to locate latest image information."
Is there a bug with the repos at the moment with flo? Also, are there
issues with getting Nexus 7 tablets to boot? Have tried wiping the cache
partition with no luck. This is a new install from the bootloader.
ubuntu-device-flash --list-channels|grep stable
ubuntu-touch/stable (alias to ubuntu-touch/ubuntu-rtm/14.09)
stable (alias to ubuntu-touch/ubuntu-rtm/14.09)

There is no "ubuntu-touch/ubuntu-rtm/stable" channel, which would
explain why you might see problems with that one.

Also, ubuntu-touch/ubuntu-rtm/devel points at the 14.09 branch, not
14.09-proposed (if you were looking for the proposed images).

I don't think there are any RTM images being built for flo right now
though. Does --channel devel-proposed work for you? That should get you
the utopic devel-proposed image, which may be slightly out of date as
well, given utopic is done and released now, so nothing should be
landing in utopic, but may get you back to a booting device.

Also, try waiting a bit longer. Sometimes my phone will sit at the
Google logo for what seems forever, and then eventually boot.
