root galaxy note 8 snapdragon odin supersu

After finding a method to enable root access on the Exynos variant of the Samsung Galaxy Note 8, developers have managed to do the same thing with the Snapdragon version as well. Rooting Samsung phones is becoming increasingly difficult, especially with Samsung incorporating Knox safety suite which makes rooting practically impossible, unless you don’t care about warranty.

Every time a conventional method of rooting is used, the KNOX counter gets tripped to 0x1, which means warranty is permanently lost. Luckily for all you Note 8 users with the Snapdragon chipset, a method called SamFAIL enables root access without tripping KNOX.

This means you get to root your Note 8 while also keeping your $1000 phone warranty. The team behind SamFAIL have managed to include root and modify the boot image of a stock firmware. The modified stock image can be flashed through Odin. This means the bootloader remains locked while having root access.

How To Root Snapdragon Samsung Galaxy Note 8 With SamFAIL (No Tripped Knox)

Note: This method works on the USA variant of the Note 8 (N950U). However, the developer says it should work on all Note 8 Snapdragon variants.

One ongoing issue with this root method is that charging is limited to only 80%, even though some users say that it is just a visual bug and the phone actually charges to 100%. Nonetheless, reverting back to stock is very easy, as all you need to do is to flash a stock firmware again.
