This guide from wiki seems old and confusing.

For my situation:

  • device: Nexus 7 (grouper)
  • origin OS: Android 4.3
  • recovery: TWRP (3rd party recovery)

And I tried as following steps:

  1. Download saucy-preinstalled-touch-armel+grouper.zip and saucy-preinstalled-touch-armhf.zip from CDimage.Ubuntu webpage
  2. adb push two zip files into /sdcard
  3. adb reboot recovery
  4. select /sdcard/saucy-preinstalled-touch-armel+grouper.zip to do an update
  5. repeat step 3, select /sdcard/saucy-preinstalled-touch-armhf.zip to do another update
  6. reboot, still Android

additional info

shell@grouper:/ $ ls /data/ubuntu
SWAP.swap
bin
boot
dev
etc
home
lib
media
mnt
opt
proc
root
run
sbin
srv
sys
tmp
usr
var

How can I install Ubuntu touch (instead of Android) on my device?

There are a couple of obvious issues:

(1.) The 'Manual Installation' instructions appear to be incomplete (for a full install).

The two files are used to 'update' an existing install. A 'full install' has 3-4 more steps.

Try using the provided tool, as described on the Wiki.

phablet-flash -b (full install, current) or

phablet-flash -b --pending (full install, untested daily)

From there, you can probably create the extra manual steps.

To download all files first (without a device attached) use:

phablet-flash -d grouper -b -D (current)

phablet-flash -d grouper -b -D --pending (untested daily)

(2.) The Google (ASUS) Nexus 7 ('grouper') is the 2012 model.

If you have (manually) upgraded your Nexus 7 to Android 4.3, or have a brand new Nexus 7 2 (2013 model) with Android 4.3, this may cause major issues.

Either wait a few weeks, or start again with a Nexus 7 (2012) still running Android 4.2.2 (or earlier).

  • as you mentioned android 4.3 may cause issues, does it means that install ubuntu touch will not wipe whole android? anyway I'll give it a try first. – Newborn Aug 04 '13 at 03:21
  • I would downgrade to 4.2 first. See: http://askubuntu.com/questions/326670/ubuntu-on-2nd-generation-nexus-7 – david6 Aug 04 '13 at 05:07
  • Install from Android 4.3 Succeeded. so far so good – Newborn Aug 04 '13 at 05:24
  • The 'current' Ubuntu Touch uses an LXC container 'Android' layer to interface certain hardware functions. This is based on Android 4.2 binaries (assumed to be present). I suggest loading a full Android 4.2.2 factory build (from recovery instructions) – david6 Aug 04 '13 at 05:28
