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
To enable Developer Options, Click on the “Settings” icon on the home screen.
In Settings, select the “General” Tab and scroll down towards the bottom.
The last option you’ll find there is “About Phone”. Select it to open.
Now click on “Software info” and look for Build number
We’ve to tap Build number 7 times to activate developer options.
Once done, it’ll say “You are now a developer!” as shown in the screenshot above.
Now go 2 steps back to the main settings page.
Here you’ll notice above “About Phone” a new option is visible which is “Developer options”.
Tap on it to open. As we’re opening it for the first time it’ll display a warning. Accept it to move further.
Now in “developer options” we’re interested in 2 things which are USB Debugging and OEM unlock.
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.
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.
Now that we’ve turned on USB Debugging and OEM unlock we’re ready to Unlock LG K20 Plus Bootloader.
