Let's add some requests for somewone build us a rom of Ubuntu, Dazzozo have make an almost stable for now ( i believe it will get stable ) rom of CM 10.2 and CM 11.0.
I think that now it's usable android parts to build a ubuntu touch rom sicerely i dont care about the games, i use ubuntu on my desktop and i will love to use it on my smartphone.
So now what we need is a custom swapped recovery as i undestand ubuntu touch install to data partition.
We have:
1GB /data dev/block/mmcblk0p18
1009MB /System /dev/block/mmcblk0p17
1GB /Internal sd /dev/block/mmcblk0p19
For android parts 300MB Should be more that enought.
Let's add the top of requests.
