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.

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

  1. I have a Metro PCS LG K20 Plus.

    The “USB Debugging” option is grayed out.

    Also, when I look at my phone in Windows 10 file manager, the device show up, but it is empty (no files or directories).

    Is there anything further that I can do to enable USB debugging? Are there USB phone-to-PC mirroring options that do not required “USB Debugging” mode?

  2. I am still Google’s Bitch lol no luck still with the elusive 3 dots that lead to setting’s Utopia where I can access developer options and all these things that magically bypass this stupid thing. Can someone please shed some light on what I can try now? I was able to access google through terms and login with my account. My account recognizes I am logged into the LG? Still no luck getting phone past Google’s verification. I’ve been at this for a couple days straight now. Couple weeks or so off and on. What happened to the 2 files I downloaded to microSD card? The ones that I was instructed to extract and boot phone from? The article goes on where I couldn’t, to access and edit the settings, and never mentions the microSD card and files? I thought for sure would be the key to solving this mystery??? Please help.

  3. I have a Verizon LG K20 Plus. Everything was going fine until I noticed “Enable OEM Unlock” is not listed under Developer options. USB Debugging is & I turned it on. Now what?

    • That shows Verizon K20 v has a locked bootloader & it cannot be unlocked. Sorry, that’s the case with most of the Verizon Smartphones.
