Samsung’s Galaxy Note 8 can now be rooted with Knox Intact

A group of developers managed to find a method for rooting the Galaxy Note 8 variant powered by the Qualcomm Snapdragon 835 SoC without tripping Samsung’s Knox protection and have detailed their findings on the boards of XDA Developers.

Despite launching in the US less than a month ago, the Snapdragon-equipped version of Samsung’s Galaxy Note 8 has already been rooted, according to a post on XDA-Developers over the weekend.

As the author notes, Samsung’s phones are some of the riskiest Android devices to root because tripping the Knox security suite by modifying your device in an unintended fashion will void your warranty and permanently disable Samsung Pay.

The good news is that this root, called SamFAIL, won’t trigger Knox and hamstring your phone. The bad news is that there are a few side effects to rooting your Note 8 with SamFAIL (but none incredibly serious, thankfully).

While many of Samsung’s previous high-end models proved to be relatively difficult to root and the indie dev scene took months to crack them, the Galaxy Note 8 seemingly isn’t one of them, at least as far as the SM-N950U model is concerned, and the same should hold true for other variants of the phablet sporting Qualcomm’s premium silicon.

The technique itself will require you to flash a modified system image containing a custom boot image using Samsung’s own ODIN tool. Given how the actual software is getting installed on the device using the company’s first-party program, reversing the process is as easy as just flashing a stock image from Samsung and since the method doesn’t trip Knox, it also won’t void your warranty.

Finally, the rooted Galaxy Note 8 will only be able to charge to 80 percent running the modified system image for unknown reasons which are likely related to battery safety. Samsung Pay also won’t work following the rooting process due to the two security switches it utilizes, though flashing the stock image back will restore its functionality.

The technique itself also won’t unlock your bootloader and is relatively straightforward, albeit time-consuming; refer to the banner below for a step-by-step guide on how to utilize SamFAIL.

Following this breakthrough, a more stable rooting method with fewer caveats is to be expected in the near future, though it remains to be seen how long the indie dev scene takes to come up with it.

There is also a separate page for the Exynos Galaxy Note 8 root, but be warned that this one will trip Knox, void your warranty and disable Samsung Pay and Secure Folder.
