How To Root Galaxy Note 8 (Snapdragon) Without Tripping Knox [SamFAIL]

After developers have discovered another way to enable root access on the Exynos variant of the Samsung Galaxy Note 8, they have also found a way to do the same on the Snapdragon variant of the Galaxy Note 8 as well. Rooting Samsung Devices keeps getting more difficult every day. Now with Samsung incorporating Knox, rooting Samsung devices is now almost impossible unless if you do not care about the warranty of the device.

Each time a conventional method of rooting is used on a device, the KNOX counter gets tripped to 0x1, which means that the warranty of the device is permanently lost.

Fortunately for the Galaxy Note 8 users who want to root their device, a method called SamFAIL can be used to enable root access without tripping KNOX.

This means that you can enable root access on your Galaxy Note 8 and at the same time keep your $1000 phone warranty. The team which is responsible for SamFAIL have also managed to include root and modify the boot image of a stock firmware. Odin can be used to flash the modified stock image. This means that the bootloader will remain locked while having root access.

How To Use SamFAIL to Root Samsung Galaxy Note 8 Without Tripping Knox

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

One main issue with this root method is that it limits your charging to only 80%. However, some users say that this is only a bug and the device actually charges to 100%. Reverting the phone back to stock is also very easy. To do this, all you need to do is simply flash the stock firmware again.
