Need instructions for installing ubuntu touch

Question

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

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

Answer 1

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).
