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.

(35.6mb)
VirusTotal Scan






Click to read the guide

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
I hope it went well xD

I believe between number 4 and 5, so at 4.5 you must enter the command "adb reboot bootloader" in order to enter fastboot mode.

That was completely my bad! I forgot I had setup adb and fastboot differently than in this guide, I updated the above post to reflect what you should actually be doing xD Thanks for catching that!~

I don't see why not, give it a shot, if it messes up let me know. I'll make a TWRP full system backup for you if it doesn't.

Let's try directing the command towards the file instead of trying to launch it like normal. Just replace " E:/Phone/recovery.img " with what ever directory your recovery.img is in. I'll attach a photo for a better example.
