How to Root Note 8 Snapdragon Variants with At&t

 The root is finally here for the US variants of Galaxy Note 8 running on Qualcomm’s Snapdragon CPUs actually. This basically includes AT&T, Verizon, Sprint, T-Mobile, US Cellular, and probably many others too. The root method/exploit has also been named SamFAIL, and it basically comes from XDA member part cyborg who actually discovered the exploit and another member me2151 who also tested and facilitated root on the US Note 8. In this article, we are going to talk about How to Root Note 8 Snapdragon Variants with At&t. Let’s begin!

The SamFAIL root actually works in such a way that it doesn’t trip the KNOX flag on your device. But, it does trigger SafetyNet check, so if you guys plan on using any apps that need passing Safety Net. Then it’ll most likely fail to run on your device rooted along with SamFAIL.

Also, the SamFAIL root method uses factory binary boot.img, the developer also says it’s important to boot the modified system on your Note 8. However, unfortunately, using a factory binary means that your Note 8’s battery would charge more than 80%. This is actually a major concern if you’re planning on root your Note 8 via SamFAIL. Because it’ll only leave you along with a 2640mAh battery power on your Note 8.

SamFAIL also doesn’t unlock the bootloader on your Note 8, and neither does it SIM unlock your phone. It only provide you root access via installing modified system files, nothing else.
