Verify steps on root and ROM -Tmo S4
I have been away from Android and recently made the switch back (Smart Move!). I bought a Galaxy Note 2 and rooted it and tried some custom ROMs. In the process I tripped Knox and then I went back and read up on it and understand how it happened. I sold that phone and got a S4 with 4.2.2 stock on it. I want to root and move up to a 4.3 custom ROM but I want to make sure I have the steps down as far was not dealing with knox again.
1. Root the phone (I used Chainfire Auto Root previously on the Note 2)
2. To move up to 4.3, I need to find a custom rom without knox and flash.
3. If I ever want to go back to stock 4.2.2, I should be able to if I never install knox (this is the piece that I really want to verify).
Tripping knox isn't a showstopper by any means but I would like to get back to the original stock firmware if I wanted to so I asking if the steps above are accurate. From what I have read, I think if I stay away from custom roms with knox, I should be okay.
Thanks for you help!
