How to use Odin and Fastboot
ODIN flashable devices
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.
If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !

Fastboot flashable devices
All downloads contain .img files bootable through Fastboot.
Make sure your device is in Fastboot mode (usually you can get there by holding VolUp+VolDown+Power when the device is turned off), then run the included script for your OS. On Linux and Mac, you may have to chmod +x root-linux/mac.sh before the script does anything.
A special boot image will load, which will install (only) SuperSU, then reboot into Android.
The included scripts perform an “OEM unlock”. If this fails, the root will not work. If it succeeds, and you were not previously unlocked (first time rooting ?), it will probably wipe your data !
For some device (Sony, Verizon, etc) you may need an OEM-specific tool to unlock the bootloader. Please do not forget to check and use this tool, if provided by the OEM.
