LG Aristo Bootloader Unlock – MS210 MetroPCS & T Mobile

Among the GSM prepaid phones, MetroPCS/T Mobile smartphones are my favorite. The reason is ease of unlocking the bootloader. AT&T prepaid phones have securely locked bootloaders which make them less appealing.

LG Aristo can be rooted after unlocking bootloader and flashing a custom recovery.

To unlock the LG Aristo bootloader the prerequisites are –

  1. Turning on “USB Debugging” & “OEM Unlock” in Developer Options.
  2.  Installing LG Aristo USB & ADB Drivers on the computer.

Once the above steps are complete. Download & Install “Minimal ADB and Fastboot” from the download link below –



LG aristo ADB mode

Connect your LG Aristo to PC & Run “Minimal ADB & Fastboot”

LG Aristo ADB connection

Type adb devices as shown above and Hit Enter key on the keyboard.

LG Aristo adb unauthorized

You can see in the above screenshot, the phone model LGMS210 is detected but showing up as unauthorized.

We’ve to authorize the compter for USB Debugging to proceed further.

As soon as you type adb devices and hit Enter, a pop-up “Allow USB Debugging?” appears on phone screen.

Hit “OK”, to authorize your PC for USB Debugging,

lg aristo adb list of devices

lg aristo adb driver window

Again type adb devices in cmd command prompt window and hit Enter.

Now you can see the PC is authorized and we’re ready to unlock the bootloader. At this time the PC will try to install the ADB drivers. Wait till the installation gets completed.

Re-insert the battery and turn on the phone. You’ll see the warning message, as shown above, every time till the bootloader remains unlocked. This is normal. Press the power button once again to get past this screen.

Now that you’ve unlocked the Aristo bootloader you may like to install custom recovery i.e TWRP on your LG Aristo. Move on to the next Tutorial to install TWRP.
