Success for Rooting Stock 4.4.2
Hey all!
Just wanted to post some updates/issues I had while trying to do the CF Autoroot/SuperSU, and what I did to make it work. I was running a bone-stock SGH-I317 with the Samsung OTA 4.4.2 Update, and getting everything to work properly was driving me nuts. Countless Google searches and XDA searches/browsing was not fruitful, unfortunately. Luckily, this isn't my first excursion into modifying Samsung/Android phones, or I would've given up in frustration a few days ago. I've rooted/modded my Captivate and my GSII, so I knew it was just something stupid somewhere that I had to fix.
I flashed the CF Autoroot with Odin, and it took with no problems. It would boot to the CF recovery (red android), do the root thing, and then reboot the phone, but every boot would generate "SuperSU has stopped" at the home screen. I tried using the SU-Update file trick, but when I did, it would report that the app was not installed. Also, flashing CWM/TWRP and attempting to boot into recovery was causing a really weird effect - the "Galaxy Note 2" splash screen was tearing and flickering sideways like the horizontal refresh was out of sync, or it would just hang at the Galaxy Note 2 Splash. Same effect if I unchecked the automatic reboot option in Odin and attempted manually. Either way, pulling the battery and restarting regularly would let it boot normally, but SuperSU was still crashing at boot.
Finally, I went in with ESFile Explorer, and found the original superSU.apk in \system\app . For whatever reason, the CF-autoroot was NOT installing the .apk automatically like it's supposed to! After going through and installing the original, followed by the update, it stopped crashing and let me have root access for stuff like TiBu and ROM Manager (which I just use to reboot into recovery, since it's easier than shutting down, then restarting with the button combo).
Then, once SuperSU was running and happy, it was time to get recovery working. Flashing philz recovery with automatic reboot was still resulting in a garbled recovery after shutting down - apparently due to the firmware/Samsung crap automatically recovering the stock recovery. Flashing philz CWM, then powering down the phone and manually booting into recovery (after fixing the SuperSU issue) finally let it get into recovery proper.
Once you've got root and recovery, the rest as they say, is history. Hoping this helps anyone else fighting Samsung's stock 4.4.2!
