Installing Ubuntu on Nexus 7 2013 deb (LTE)

marxjohnson · 19 Sept 2016, 11:22

@doniks I finally got it working! I had to use the -w flag when doing the fastboot commands.

The full steps I used for the successful flash:

ubuntu-device-flash touch --channel=ubuntu-touch/stable/ubuntu --device=flo --bootstrap
# Reboot into bootloader
fastboot flash -w boot boot.img
fastboot flash -w recovery recovery.img
# Boot into recovery
ubuntu-device-flash --server http://system-image.ubports.com touch --channel ubuntu-touch/rc-proposed

@doniks Yup, that is what I meant ... the complete official flo image. You can try installing it without the --bootstrap option and if you are lucky you won't lose any data.

I did try it now:

device boots fine
no data loss
OTA 13
camera works
audio does not work
video playback does not work
initially wifi didn't work either, but it does work now .... dunno
initially bluetooth didn't work either, I was about to give up, but after the Idon'tknowhowmanyreboots it works!

Mhm, now how do I get sound and video back ?!

@doniks There is no way I know of. You are either stuck with not really functional flo's image or you flash the deb stuff on it again but you'll have to say good bye to the bluetooth and camera. The only way to fix this is either to somehow compile the whole image on your own or ask the owner of this server for some help - if he would be kind enough to talk to you. In any case, good luck - I was stuck at that point long enough to lose interest :(, that is the only reason why I got rid of my N7.

Yeah, seems like. I have switched back now by replacing the android lxc system.img inside the ubuntu system image in the new flo installation with the one from the ubports device.tar.xz . Camera and bluetooth gone, sound and video back, but ota13 remained.

Also, judging from the kernel configs, it seems that in the flo image there is a newer kernel, but I cant see any difference in the running system.

I wouldnt mind doing it, Im just stuck. I was staring at repo manifests, Makefiles and lunch, brunch scripts, but I couldnt figure out what I would have to do to get the source tree I got with repo from either ubports or canonical to change it such that it builds a flo image. Also, I would suspect, that 'just' building it would only bring you to the point without bluetooth.

or ask the owner of this server for some help - if he would be kind enough to talk to you.

Didnt get very far there. Dont wanna put words in his mouth, but seems he doesnt have an N7, so he cant really test.

In any case, good luck - I was stuck at that point long enough to lose interest :(, that is the only reason why I got rid of my N7.

Thanks! Your tips where most helpful!

@zubozrout we have fixed the problem on the system image server, you can try to install deb now with the installer or ubuntu device flash and everything should work, without any hacking!

@Flohack Thank you. Sadly I don't have that device for something like 2.5 years but am very happy it got fixed. Nice work :).

@marxjohnson could you give it a spin?

@flohack Hi there, I appreciate this is quite some time after the thread was active, but I still have a Nexus 7 2013 LTE unit, whereby the bluetooth non-function issue and telephone audio issue are present. I wonder, is the thread for further ongoing improvement of this N7 2013 LTE ubports distribution mothballed, or is there chance to continue? Honestly, i'd have a go at contributing, but I just don't think I'm knowledgable enough as yet, though i suppose I could test. Your thoughts much appreciated. PT

@paultimperley You are probably better off re posting here https://forums.ubports.com/category/58/google-nexus-7-2013-lte-wifi in our newish sub categories. Let me know when you have done so and I will lock this thread.

@paultimperley I have a fix/workaround for Bluetooth, not sure about telephony issues as I only have a data SIM I can use for this device. Come on over to: https://forums.ubports.com/topic/6056/nexus-7-lte-general-bugs-problems at least for a bluetooth workaround.
