LG K20 Plus – How to Enable USB Debugging and Developer options

USB Debugging and OEM unlock needs to be turned on within the developer options to unlock the bootloader of LG K20 Plus. However, if you’ll look for developer options in Settings, you won’t find it anywhere.

In the earlier versions of Android, developer mode had quite a few options so it was kept visible by default. Since Lollipop, many more features are added which are meant for developers only and a normal user can do more harm than good by messing up with these settings. So keeping in mind the majority of the users its kept hidden but can be enabled quite easily with few taps on Build Number. Let’s see how to do this.


How to enable USB Debugging on LG K20 Plus

Before turning ON “USB Debugging” make sure that your K20 Plus is not connected to PC. It would be greyed out and won’t let you enable if connected to the computer.



LG K20 Plus Enable OEM Unlock

Now look for “Enable OEM unlock” and toggle it to ON position as shown above.

If we’ve to unlock LG K20 Plus bootloader OEM unlock must be turned ON along with USB Debugging.

However, you must note that by turning on OEM unlock, Google’s Factory Reset Protection (FRP) gets disabled, that means you won’t be prompted to verify your last synced google account if doing a hard reset with Volume Down and Power button combination.

Once you unlock the bootloader of your LG K20 Plus you cannot turn off “OEM Unlock” unless you relock the bootloader.
