Unlocking instructions

My device came with unlocked bootloader, so fastboot flash just works.

Known issues

Almost nothing works except booting up into the Ubuntu Touch shell.

Trying the image

bzr branch lp:phablet-tools
cd phablet-tools
./phablet-flash community --device u9200

== How to build it yourself==

Check out the full phablet tree as described in

https://wiki.ubuntu.com/Touch/Building

!! Use the phablet-saucy branch !!

Grab the manifest file from here, put it in .repo/local_manifests/huawei_u9200.xml then run repo sync

https://gist.github.com/janimo/5412625

repo sync will grab the device/ and kernel/ trees for this device from the below URLs

Now you need to get the proprietary vendor bits without which the image is not working at all. There are a few ways to do this, 1 being the recommended one if you have a working Android device.

1)Have a device plugged into USB and accessible via adb, then

cd device/huawei/u9200
./extract-files.sh

2) Download the updater .zip file from Huawei http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDY4ODc= unzip it unpack the resulting UPDATE.APP using this perl script https://gist.github.com/janimo/5412727 This will results in over a dozen files, blobs corresponding to each partition in the device, unknown_file.12 being the system partition in a fastboot sparse format that needs to be converted in a properly mountable ext4 filesystem image

apt-get install android-tools-fsutils
simg2img unknown_file.12 image
mkdir system
sudo mount -o loop image system

Now you have the original Android rootfs under system/ In the source tree under device/huawei/u9200, you can call the same extract script telling it to copy from an existing local path instead of adb pulling from a connected device

VENDOR_DIR=/path/to/this/loopmounted/system ./extract_files.sh

3) Get hold of an existing vendor/ dir and just drop it/clone it into under vendor/huawei/u9200

Now on to actually building it:

. build/envsetup.sh
brunch u9200

The result should be under out/target/product/u9200

You can fastboot flash the boot.img recovery.img system.img and userdata.img partitions, then boot into recovery and pick sideload in the device. On your machine

adb sideload saucy-preinstalled-touch-armhf.zip

That zip being whatever Ubuntu image you download from http://cdimage.ubuntu.com/ubuntu-touch/daily-preinstalled/

Redistributability

The proprietary blobs are probably not redistributable.
