The Samsung Galaxy Note 7 is the new kid on the block, so to speak, and developers have been working to get a root method working for the new smartphone. While some users love Touchwiz – Samsung’s own UI that is on top of Android – others don’t, and some may just want a quick way to freeze and delete all of the pre-installed apps that they don’t want to use. There are many reasons to root a device. Typically Samsung smartphones are tougher to root, especially these days with Samsung KNOX playing a big role in security of their devices. And that’s an issue with the Galaxy Note 7 as well.
Chainfire, who has successfully found methods to root countless Android smartphones and tablets in the past, has just released a new beta version of SuperSU, this is version 2.77. While it is a working version of SuperSU, it isn’t without its flaws. In his post on Google+, Chainfire notes that there are new built-in protection methods that Samsung has applied directly to the kernel on the Galaxy Note 7. The main issue here is with “privileged” processes that has a uid/gid value equal to or below 1000 is executed, the device will reboot. Most root processes have a value below 1000, so as you’d expect, it does immediately reboot. However, Chainfire has created a workaround for this, when the SuperSU systemless boot image is created, the kernel check is also patched.
It’s important to note here that rooting your Galaxy Note 7 will indeed void your warranty. And that may not be the best idea, especially given that you just spent $850+ on this new smartphone. It’s also very possible that Samsung could push out an update and block this workaround for rooting the Galaxy Note 7. So while it will work for now in getting root access to your Galaxy Note 7, it may not in the future. Keep in mind that this is only for the Exynos version of the Galaxy Note 7, and not the Snapdragon 820 version. That version is likely being worked on as we speak, however. Those that are interested in using SuperSU 2.77 beta, you can download it from the link below. There is also a TWRP flashable ZIP available if you wish to flash through TWRP. Currently, CF-Auto-Root is not available as the methods that Chainfire has used have not worked.
