[LG Stylo 2 Plus ROMs, Kernels, Recoveries, & Other] Dark Bulbasaur:
Root for MetroPCS/T-Mobile LG Stylo 2 Plus Android 7.0 Nougat ( LGMS550 & LGK550 )

Everything you need to root your LG Stylo 2 Plus running on Android 7.0 is packed into Stylo2.zip for convenience

If the link ever goes down send me a private message, I'll have a few backups of this laying around.

This method works on MetroPCS (LGMS550) and T-Mobile (LGK550) phone models.

Before doing anything, on your computer you need to extract Stylo2.zip to your Desktop, and install:

minimal_adb_fastboot_v1.4.1_setup.exe (Install this into the Stylo2 folder)

PhoneDrivers.exe

1. Enable Developer Options on your phone, and navigate to the Developer Options page.

Enable OEM unlock

Enable USB debugging

Enable File Transfer

Place no-verify-opt-encrypt-5.1.zip and SuperSU.zip onto your external sd card.

2. After placing the two zip files into the root of your sd card

Enable Charging mode

Authorize your computer for USB debugging

3. Launch MAF32.exe from the Stylo2 folder

(This is Minimal ADB and Fastboot)

4. In the window that pops up type:

adb devices

It should look like this:

PS C:\Users\Hyperion\Desktop\Stylo2> adb devices

List of devices attached

LGMS55010ca1cf1 device

PS C:\Users\Hyperion\Desktop\Stylo2>

5.Boot into the bootloader by typing

adb reboot bootloader

PS C:\Users\Hyperion\Desktop\Stylo2> adb devices

List of devices attached

LGMS55010ca1cf1 device

PS C:\Users\Hyperion\Desktop\Stylo2> adb reboot bootloader

PS C:\Users\Hyperion\Desktop\Stylo2>

6. Next you will be unlocking the bootloader

(This will erase everything on the Internal Storage)

In the PowerShell window you will need to type:

fastboot oem unlock

PS C:\Users\Hyperion\Desktop\Stylo2\Stylo2> fastboot oem unlock

...

(bootloader) Erasing userdata and cache

OKAY [ 12.386s]

finished. total time: 12.389s

PS C:\Users\Hyperion\Desktop\Stylo2\Stylo2>

Your data should now begin to wipe.

7. Once finished with the data wipe, you will need to flash the recovery.img to your device.

In the PowerShell window you will need to type:

fastboot flash recovery recovery.img

It should look like this:

PS C:\Users\Hyperion\Desktop\Stylo2> fastboot flash recovery recovery.img

target reported max download size of 262144000 bytes

sending 'recovery' (15588 KB)...

OKAY [ 0.508s]

writing 'recovery'...

OKAY [ 0.406s]

finished. total time: 0.918s

PS C:\Users\Hyperion\Desktop\Stylo2>

This is where it can get tricky.

8. Turn your phone off.

Unplug your USB cable

Take out your battery

Put your battery back in

Read next step before turning your phone back on

9. You will now need to boot into TWRP, which isn't the most fun thing to do.

(This process begins after the screen prompt that says your phone can't be authorized has already came up.[if it pops up at all])

Get comfortable with this process before attempting it.

Hold Vol Down + Power (Don't let go)

Once you see the LG Logo let go of the power button briefly

Press the power button while still holding Vol Down

Don't let go until a white Factory Reset screen comes up.

Select Yes, then on the next screen select Yes again

(This should boot you into the flashed TWRP Recovery Image)

If you do not boot into TWRP, repeat Process 1-8 until success

(excluding unlocking your bootloader, once unlocked it does not need to be unlocked again.)

10. Assuming you are in the TWRP menu, you will need to wipe the device again.

Navigate to WIPE in the top right

Follow on screen instructions to wipe the device

Click Reboot, and choose Recovery

It wouldn't be a bad idea to make a Backup at this point

11. Once back at the TWRP menu again, you will need to start flashing .zip files.

Click Install

Click Select Storage in the bottom left

Select no-very-opt-encrypt-5.2.zip

Swype to confirm Flash

Press back until at the TWRP main menu again

Click Install

Select SuperSu.zip

Swype to confirm Flash

Some people have had better luck flashing no-very-opt-encrypt after flashing supersu. (I can not confirm this)

12. Reboot to system, let the thing boot loop a couple times at the MetroPCS screen

Cross your fingers until your phone boots up

Download a Root Checker

Check your root access.

If all went well your MS550/K550 running Android 7.0 Nougat should be rooted :D

I hope it went well xD
