State of things

Booting to the Unity 8 shell works using flipped containers (i.e. booting into Ubuntu directly, then spawning an android container, instead of the old way of booting into android, then starting an Ubuntu chroot).

This port is entirely based on the work of the Andromadus team. They maintain an inofficial CyanogenMod port for the Desire Z. If a feature is marked as "Perfect" that doesn't mean it works out of the box with only Ubuntu Touch and CyanogenMod. It means that it works without patches to Andromadus/Ubuntu/CyanogenMod, but the Andromadus patches are obviously required.

Explanation

Perfect

Everything works, all patches included in Ubuntu proper

Working

Works, minor issues only, some patches pending

W-I-P

Work in progress

Blocked/Broken

Severely broken, unusable or progress is blocked

What

Status/Comments

Graphics

GUI works with Andromadus repos (so obiously patches required for CyanogenMod)

Boot process

Works with some patches required for the Ubuntu initramfs and android container scripts for partition detection (i.e. hard code /dev/mmcblk0p26 etc.), Ubuntu plans for a more general solution for this

Rotation

does not work, reason unknown

Cellular Radio

No idea, no spare SIM card to test

Wireless network

works with Andromadus repos (possibly minor patch for Andromadus repo is required, not tested without that in long time)

Sound

don't know yet

Touch

works with Andromadus repos

Camera

Camera libraries depend on libjnigraphics which is not built for Ubuntu Touch and seems to have a lot of dependencies, so it is unlikely that this will be fixed

Video Decode

don't know yet

Suspend/Resume

don't know, seems to work (?? how to test ??)

Flashing

Patch required to flash Ubuntu parts, see Launchpad bug 1145984 and updated flash scripts in the ubuntu zip file modification script on github

Storage Requirements

/data is only 1gb on the Desire Z. The modified rootfs has some tweaks to free up some space, e.g. the swap file is removed from the tarball. This is probably not upstreamable and might get worse in the future as new features are added to Ubuntu Touch.

Installation

  • Put these files on your SD card (download from google drive link above):
    • cm-10.1-20130728-UNOFFICIAL-vision.zip
    • modified-saucy-touch-armhf-20130726.1.zip
  • Wipe/format data and system (this is important, even when just updating to a newer *-touch-armhf-*.zip!)
  • Flash both zip files through recovery, the cm zip first, then the touch-armhf zip.
  • Reboot, read "known issues" below

Unlocking instructions

See XDA Developers forums.

See table above.

Known issues

  • Sometimes it fails to start (black screen) and surfaceflinger keeps on crashing. ADB still works. Workaround: Power off and reboot.
  • Phone app is unusable (GUI doesn't fit into the screen)

The image

How to build it

  • Use my github repo linked above to init the source tree using the repo tool (branch "master").
  • ". build/envsetup.sh" in the the source tree root
  • "brunch cm_vision-eng" in the the source tree root
  • The android zip file will be created in out/target/product/vision (cm-*.zip)
  • Download Ubuntu rootfs from http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/ and use the rootfs modifier script linked above (github) to make it work for the Desire Z. (see instructions on github)

Redistributability

The Image contains blobs from https://github.com/Andromadus/proprietary_htc_vision with unknown redistributability status.
