Potentially the process could be documented here so that other people could build there own. I don't know how many people still use this phone, but it would be a good learning process.
So is anyone else interested? Currently I know next to nothing so we would be starting from there
I have been learning how to work in the android environment for a little while now, and want to move onto learning how to create roms from AOSP rather than other peoples existing work. This would allow a lot more freedom. The current dream is to create a JB 4.1.2 rom from AOSP, then release it as a base rom to allow anyone else to rip it up just as they want. Once developed it could be used to show examples of how to use apktool and others to customise your own rom.
