This is developed by geiti94 and this article was originally shared on xda-developers, and as mentioned in the title it’s unofficial. Here we share it with a little changes in the article and guide, just to make it a little bit more comprehensive if possible. The links to original article can be found at the end of the article, and for more information than provided here, please go to the XDA forum.

Please use CPU-Z to find out your CPU and Chipset variant.

Exynos ONLY
Please note that it is NOT compatible with Snapdragon variants including but not limited to American(U/A/T/P/V), Chinese(0/8/6), Hong Kong(0), Japanese(SC-*), Canadian(W) variants.

Special Notes:

  1. DON’T FORGET TO ENABLE “OEM UNLOCK” (located in Setting/Developers Options).
  2. KNOX will be tripped when you flash custom binaries to your phone.
    (Your warranty may be voided. However this may not affect you if your country forces Samsung to provide hardware warranty regardless of software status.)
  3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries. (You can flash custom ROMs if you want to keep the OS up-to-date.)
  4. All apps that use KNOX like Samsung pay, Secure Folder, etc may no longer work.

  7. Reboot into “Download Mode” and flash TWRP tar into your device with Odin in the AP field.
