CF Auto Root From The Repo For Galaxy S7 EDGE [SM-G935/Exynos]

Repo now provide CF-AUTO-ROOT for Galaxy S7 Edge.
Before performing flashing, it is good to activate OEM UNLOCK of Developer Settings. 

DOWNLOAD
Odin
Fastboot
USB Driver S7/S7EDGE

INSTRUCTIONS
All downloads contain .tar.md5 files flashable in ODIN as PDA.
Make sure your device is in ODIN download mode (usually you can get there by holding VolDown+Home+Power when the device is turned off), then start the included Odin3-v1.85.exe file, press the PDA button, select the .tar.md5 file, and click Start. You can find more detailed instructions and assistance at XDA.
A modified recovery and cache partition will be flashed, which will install (only) SuperSU, then clean-up the cache partition and re-flash the stock recovery.
For the root to work, the device must reboot into recovery. Most devices will do this automatically after flashing these files, but in case that does not happen, please boot into recovery manually.

NOTE
CFAR's display code isn't yet compatible with the S7, as such, there is no output on screen. This means that after flashing with ODIN, the device will only show you the S7 logo, and it seems like nothing happens. Just leave the device alone for 5 minutes. It'll reboot a few times, then boot into Android, but now you have root.
If it still doesn't do anything after 5 minutes, something has gone wrong, and you should probably reflash your stock boot.img and recovery.img.
