LG Stlyo 3 Plus Root Android 7 MetroPCS & T-Mobile Tutorial


Tap on the “Home” icon to move from Backup page to TWRP home page.

Hit “Install” and click on either Magisk.zip or SuperSU.zip file to install as desired.

You can flash either of them but not both.

I’ve flashed Magisk as I found it more useful with more features.


Swipe the bard towards the right to flash Magisk-v18.1.zip file

Tap on “Reboot System” to boot phone.


STEP 3: Installing Magisk Manager & Checking Root Status

Open “Tools” Folder and Look for “File Manager”.

Open the File Manager and click on the transferred file, MagiskManager-v7.0.0.apk file to install it.

As we’re not installing the apk file from play store, we’ve to enable “Unknown Sources” as shown above.


After turning on “Unknown sources” go back and try to install the Magisk.apk file once again.

This time the installation will go through.

Tap “OPEN” to run the Magisk Manager app.

Now that Magisk Manager is installed, let’s check the root status via “Root Checker” app.

I’ve downloaded this app from the Play Store.

You can see Root checker has verified the device as Rooted!
