http://forum.xda-developers.com – Hello I like port a rom based in CM 7.2 RC0 to CM 7.2 STABLE. Is there a tutorial for doing this? I have a tablet (Arnova 10) for which I was working on this rom unofficial, but the developers had problems between them and abandoned the project. I would like to pick up, but the first thing is to port a version of CM 7.2 STABLE If there is any tutorial or someone willing to make the port has, say it here or write me a PM Thanks and regards (HowTos)
