It's been a while, and there was not a single rom for our mt6577 based device.... Since now. One of devs from Poland forum made a port from ZTE v970/v970m for it, and it is still in alpha stage..
For now, there are a lot of things that don't work such as : camera, camcorder, microphone ... There are lags after phone calls etc etc ... So it is not for daily use, but it is quite interesting, because we now have hope for, at least, custom JB Update...
So, here is original thread on that Polish forum :
Latest Alpha build is 6b, and link for it is here :
Note : This rom is experimental and unstable. Use it on your own risk !!!
Install it like always. .. Wipe everything and then install from zip...
p.s. Do backup first
