I bought a second hand red s3. I believe this is what you people call rooted or something along these lines. I have things on my phone that I do not want. Its unlocked which is a must because it was originally with another carrier. I want to keep this. Other things I have; something called superuser, c-rom, kitkat 4.4.4 and maybe something else I'm sure. I'm not very good at this. In short, I had an s3, it was great and I think it used jellybean maybe? I want this back because I liked this way better. More user friendly. Is it possible to change from what I have to what I had and remain unlocked? also, if there is at least a 1% chance of bricking my phone or relocking it, I don't want to do it. Layman's terms will be much appreciated. Thanks in advance.
