  1. Is this CF Auto Root optimised for 4.3? Because I just tried it and it does not work. SuperSU is installed but it cannot get root access.

    1. Just have the same problem here

    2. Try to update SuperSU from Play-Store, then launch SuperSU and disable knox. It worked for me :)

    3. Already updated the supersu and disabled knox but still no root access. Fix it pls

    4. i have the same problem

      how this issues can be resolved?

  2. Same - Stock 4.3 S3, all goes and says pass, installs the SU but root checkers all show no root access.

  3. this didnt work for me and i had to unroot by flashing back to stock. what do I do?

  4. CAUTION, you definitely lose the warranty!
    because in Download mode, a line will be added:
    Warranty Knox 0X0 = False
    Warranty Knox 0X1 = True
    You lose the warranty if warranty = 1
