Migrate from GB to JB
it's been more that a year since I've rooted my friend's Galaxy S and flashed DarkyROM on it and he would now like to have one of JB 4.2.2 (or even 4.3) ROMs. Could you please point me in right direction (preferably with links), what steps and procedure should I perform to make it work? I really don't want to mess something up.
The only thing I know for sure is to make EFS backup before flashing: http://forum.xda-developers.com/showthread.php?t=859914
but other than that... well, I hope for your help.
