Well I root an s3 yesterday, and I cant find the post anymore.
on 4.3 CF root method didn't work.
So I tried a method from a post that I can't find.
Basically, from the stock 4.3 Bell rom :
- install samsung usb drivers
- flash the latest TWRR ( I used : openrecovery-twrp-22.214.171.124-d2att.tar) via odin 3.7 through PDA box.
- Then I put on the internal storage : UPDATE-SuperSU-v1.65.zip and DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V1.0.zip.
- reboot in recovery TWRP (vol up and home)
- flash those two zip.
and I was rooted, go to the play store and update superSU.
I run titanium backup to be sure, and it worked.
For the unlock, I didnt find anything, I guess we have to pay the unlock code, which is kind of expensive, around 20 - 30$ usd.
My htc one S was only 5$ ...
