  1. I attempted this and it failed. I had previously rooted on 4.3 using the saferoot method. I had to upgrade to 4.4 using Odin, and when I attempted the root I got a "Pass." However, superSU said the binaries were not installed and check root failed as well. I'm going to try a factory wipe and re-flash 4.4 and try the root again.

    1. I attempted it again. After reformatting and flashing the stock ROM superSU installed itself again. I ran the root and it disappeared. I get the screen with the pirate droid on the auto-reboot saying it is rooting the phone, but superSU is no where to be found. If I install it from the google play store, it says the binaries are not installed and the phone is not rooted. Any help you can give would be appreciated.

  2. Hold on if you haven't been helped yet I will give you the root method that I used w/o using odin.. let me find the link worked like a charm for me and I am a USC galaxy s4 user, on mk2 sch-r907

    1. Thank you very much for the reply. Chainfire did update the auto-root files for the 4.4 update and this method did eventually work. I guess I was just too impatient, but the creator of the tutorial didn't verify that the technique was working at the time of post. Now I'm looking into flashing a custom ROM because I've always wanted to try. I just need to do some more research to see if I need to unlock the bootloader for my phone, and how one does that after the 4.4 update.

    2. What was the link that you used? I have tried many times with no luck

  3. so I had the same thing happen to me what do I do

  4. I have done it step by step and the dust button is not there when I go to start it what am I doing wrong?
