LG K20 Plus Unlock Bootloader – MetroPCS MP260 & T-Mobile TP260

The best thing about MetroPCS / T-Mobile phones is, their bootloaders are unlockable, and that’s the very reason their phones are the most popular among the prepaid smartphones.

LG K20 Plus is one such MetroPCS Smartphone. Once we unlock its bootloader, we can easily flash a custom recovery such as TWRP. In TWRP can easily flash Magisk or SuperSU to root our K20 plus.

Bootloader unlock should not be confused with sim unlock. Your device will remain locked for other carriers even after unlocking the bootloader. Sim unlocking is an altogether different thing and needs to be dealt with in a different manner.

Now let’s proceed with the bootloader unlocking –

Before connecting your phone to the computer you should install the LG K20 USB Driver on your PC.

Before proceeding with the below procedure, we’ve to turn on “USB Debugging” and Enable “OEM unlock” within the developer options.

Wait for the K20 Plus ADB Interface driver to install.

If the driver installation fails, update the ADB driver manually.
