FAQ's:

My WiFi credentials keep on getting erased after a reboot. What gives?

It's SO easy to install and it takes most if not all of the hassle out of it.

How do I enable USB debugging?

A: Go to Settings>About device and tap Build number until it shows Developer options has been enabled.

I'm stuck on the LTE splash screen. What do I do?

A: Press and hold the Volume Down + Power button down until your phone restarts. If you keep on getting stuck at the LTE splash screen you may have to factory reset your device. As soon as your phone restart quickly press the volume up + home + power button and let it boot into recovery. Wipe data/factory reset and cache partition.

I'd like to unroot and return to factory stock. How would I go about this?

A: Head on over to [MENTION=1599591]psouza4[/MENTION]'s post HERE and follow his steps in the return to stock section. The steps are easy and he's posted mostly all the firmware.

[*]Does this method trip Knox?

A: No, it doesn't. And flashing back to stock will allow Knox to work again, as long as you didn't flash files from other sources (there are some that will trip Knox, so be careful).

[*]Does Samsung Pay work?

A: No, sorry. They can detect the rooted boot environment through a driver, so you can't even hide root from the app using RootCloak.

[*]Does Android Pay work?

A: It does, but you have to make a change that disables root and then reboot your phone. You can toggle this back/forth without flashing, but you either get root or Android Pay at any one time.

[*]What happens if I brick my phone?

A: As long as there are stock images to flash back to, it's almost impossible to do this no matter how badly the process goes. Check that we have stock images; if we do, then we can always flash them over the device using the unroot method in this guide. That practically guarantees a return-to-stock experience for a phone as long as it doesn't have any serious physical damage preventing it from powering on.

[*]I installed the ADB system-wide on my Windows computer/laptop, but I see "'adb' is not recognized as an internal or external command, operable program or batch file".

A: Your user profile path can't contain a space. That means if your Windows user is 'Somebody Nice' and thus your Windows user path is 'C:\Users\Somebody Nice', the install will fail. You can create another user on your computer (if prompted for a Microsoft login, choose to make only a local account) and enter a short, single-word name for your user. Sign into and use that user profile instead. Also, the path where you extract the SuperSU package can't contain a space, so try extracting them to somewhere simple like perhaps C:\S7Root.
