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 –
