All Samsung Unlock Bootloaders Files
All Samsung Unlock Bootloaders Files 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 !
