I need your help. I have my i9300 since October 2013, and it's still running stock 4.3.
I want to install a KK ROM, but I have a few questions.
- Right now, is there a stable KK ROM, that I can use as a "daily driver"?
- If i need to send my phone to warranty, is there a way to revert to 4.3 stock?
- Before installing the custom ROM, do I need to backup the "efs" folder?
