LG Stylo 3 Plus USB Debugging, Developer Options & OEM Unlock – How to Enable

LG Stylo 3 Plus is one of the few LG android phones with an unlockable bootloader. With an unlocked bootloader, we can easily root our Stylo 3 plus, flash a custom recovery (TWRP) & install a Custom ROM.

However, in order to unlock the bootloader, we need to Enable USB Debugging & OEM Unlock. Both of these options are found within the “Developer Options”. Let’s check out how to do this with the help of the following screenshots.

  1. I am able to do all the above instructions but for some reason my pc still wont recognize my device. When I click the usb options tab it doesn’t matter what I choose the usb settings block will remain on charge only. I think I read somewhere that there was a part of the stylo that is set to remain locked> Help me please.

  2. I have a straight talk stylo 3 and can’t get the system to recognize any debugging apps, and therefore can’t run usb debugging. Help?
