How to root Snapdragon Galaxy Note 8 Without Tripping KNOX (SamFAIL)

It is a well-known fact that rooting a Samsung device isn’t easy. The security patch of Samsung KNOX won’t allow users to root the device and if the attempt has been made it leads to tripping of KNOX which will further lead to the annulment of warranty. Besides tripping it also disables the Samsung Pay app. No matter how much users try they can’t bring the old KNOX back.

The same thing happened with Samsung Galaxy Note 8. A lot of research has been done to root the device and mostly all trials have been failed. Developers have found a new way to root the Exynos version earlier and now they had even found an option to root Snapdragon version too. This rooting method is known as SamFAIL.

Here is the step by step procedure to root Snapdragon Galaxy Note 8 without tripping KNOX
