First of all I'm gonna say Omnirom is the best.
My GS3 (international) is now super smooth, it's way better than 4.3.
I've got 1 question however:
How can I root my phone now? I somehow expected my phone to remain rooted after installing Omnirom, but it didn't.
I've got CWM recovery. I tried CF auto root, but that didn't work.
Does anyone know how to get root acces on my GS3 (I9300)?
