I trying install Ubuntu-touch on Nexus 7 3G, using Touch Install. But on the step 4, I received an error:
~ $ sudo phablet-flash -d grouper -b
phablet-flash: error: argument : invalid choice: 'grouper' (choose from 'cdimage-touch', 'cdimage-legacy', 'ubuntu-system', 'community')
As of version 1.0 (of phablet-tools) the syntax you need changes to:
phablet-flash cdimage-touch -d grouper -b
You should not need sudo for this command.
See: phablet-flash -h OR http://sergiusens.github.io/posts/updates-to-phablet-flash.html
Verify what version you have with: dpkg -s phablet-tools | grep Version
This new version definitely works for Nexus 7 and Nexus 10, but I have not yet tried with Nexus 7 3G.
The ASUS Nexus 7 3G (and in particular the 32 GB model) are somewhat different from the base model of the Nexus 7 ('grouper'). They have support for GSM 3G/4G and other low-level firmware changes.
Before Ubuntu Touch was 'flipped' (still ran Ubuntu in a container inside Android), this did not provide an insurmountable problem. However, the additional features not found in grouper were also not available.
Now with the 'flipped' design, and with current changes to the underlying Ubuntu Touch OS and UI, only the base model Nexus 7 (grouper) is currently supported.

Nexus 7 3G [2012] problem with ubuntu touch
Nexus 7 3G is not equivalent to grouper.
Nexus 7 is a commercial name that hides a lot of different hardware configurations in it.
If the hardware codename is tilapia [2012, 3G] or razor [2013] the device will not work without modifications or what people call ports, please refer to https://wiki.ubuntu.com/Touch/Devices

This question/answer is no longer current.
As of March 2013 use of the phablet-flash tool has been deprecated, and you should use ubuntu-device-flash.
Support (as reference hardware) for the Nexus 7 (original model) is also now deprecated, with development focused on: Nexus 4 smartphone, Nexus 7 (2013) tablet, and Nexus 10 tablet.
Support for Galaxy Nexus is "maintenance only" (major bug fixes).
