I used channel:
devel-proposed - Follows Ubuntu's devel-proposed channel with testing Ubports android images

to be on more current version and now I have instead of ubuntu touch 15.04:
manta=20160126
but has bootloop

Then I used channel:
rc-proposed - Follows Ubuntu's rc-proposed channel

And I got:
manta=20160126 with version=235
Looping again

Now for channel:
stable - Follows ubuntu's offical stable channel

And I got:
manta=20160126 with version=7
Looping again

So I am stuck with Android and Ubuntu Touch 15.04...

Hi Yougo,

I am trying ubports dualboot myself right now. Try this one instead of your Terminal command:

• ctrl+alt+t
• gedit .bashrc
  export CUSTOM_SERVER_URL=http://system-image.ubports.com
• ctrl+d
• ctrl+alt+t
• adb shell "su sh 'cd /data/data/com.canonical.ubuntu.installer/files/ && echo $CUSTOM_SERVER_URL > custom_server && chmod 777 custom_server'"

I am right now making a test myself.

Hello all,

as described here, theres is no solution to this error by now:
Nexus 10 startup

How can I get in touch? I am long-time Ubuntu desktop user ready for testing.

Thanks all!
