Samsung Galaxy Note 8 users who need development on their device can now install TWRP custom recovery and enable root. Unofficial TWRP recovery (twrp-3.1.1) is now available for Galaxy Note 8 Exynos variant. However, since Galaxy Note 8 uses dm-verity check (verified boot) you need to by-pass the check. If not, your device will not boot. You can get root on the device via SuperSU or Magisk.
Keep in mind that installing TWRP custom recovery on Galaxy Note 8 is not a simple process. Users should take extreme care, otherwise end up with a non booting device. Also the process will void warranty and wipe data. Check out the guide to know how to install TWRP recovery on Galaxy Note 8 (Exynos) via Odin and get root access.
The benefits of TWRP recovery and root access are quite a lot. Installing custom ROMs, customizing the device, strip off bloat apps, perform full backup of the phone, etc. are some of the main uses of TWRP recovery and root.
Warning: KNOX will be tripped once you flashed TWRP recovery. It will void your device’s warranty and will not get further official OTA software update. Also, it will wipe your device completely. Backup data you have on the phone before proceeding.
Note: The below guide supports only Galaxy Note 8 N950F/FD/X/N (Exynos variants). It will not support Snapdragon variant Galaxy Note 8.
