If you do boot back into android, you will need to re-flash TWRP (Steps 1-4)

At this point, you will see the TWRP splash and reach a screen asking you if you want to allow system modifications.

By swiping right, you will trigger dm-verity, and if you don't follow step 8 you will be unable to boot!

If you are going to root your device or follow the rest of these steps, then it is safe to swipe right and enable modifications.

Step 8:

Only if you want internal storage or data to work in TWRP:

Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".

WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!

Go to [Reboot] -> [Recovery].

Step 9:

Please consider backing up your stock boot partition in TWRP before proceeding to the next steps!

Step 10:

If you want to be rooted with SuperSU:

Download the latest SuperSU stable by Chainfire.

Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.

-or-

If you only want a bootable system partition or writable data in TWRP:

Download dm-verity and force encryption disabler.

Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.

Step 11:

Go to [Reboot] -> [System].

Now upon reboot, the phone may loop a few times and take up to 5 minutes to complete the process.

When you get into the device, run through setup as normal and you will have SuperSu installed and you will be rooted.

I can not verify Magisk Root Yet but will be attempting to do so soon.
