I am new to rooting and roms. I have rooted my phone. As I search for a Rom to install , I understand how to install BUT my concern and confusion is to which Rom file is correct to use. All the ones I find are for Samsung galaxy s3 I9300 and warnings state only use on that specific phone. Is there a difference on I9300 and my sgh-t999? I really don't want to brick my phone. My goal is to remove bloatware and improve little glitches like screen load and battery life.... which I found that omega might work just really confused on which Rom file is safe for my phone. Please can anyone help me with this?
