thank you i was kinda wary of cf auto root. i tried it on a verizon one that i had and it always failed lol. but it worked on this one! lol. i had a s3 that was verizon and updated to 4.3 and i couldn't download any aosp roms and could only install i think it was mlb. with it being rooted this way can i install any rom? and do i need to install cwm or a recovery?
I just rooted yesterday again (after being on stock 4.3 touchwiz for the longest time, what a disaster). I used the CF auto-root method as well. I downloaded + flashed TWRP recovery using odin, and was all set to install AOSP roms. You can use CWM if you want but a few devs recommend TWRP so that's what I have stuck with.
