How To Boot LG V20 Fastboot Mode

Fastboot is a special mode for writing data to your phone’s flash memory. You can use it to flash images such as recoveries (TWRP), bootloaders, and kernels to your Android device (and so much more). Here’s how to boot LG V20 Fastboot Mode.

How To Get To LG V20 Fastboot Mode

  • Turn off your LG V20.
  • Wait for 10 seconds.
  • Next, connect your phone’s USB cable to your computer (do not connect to phone).
  • On your phone press and hold the Volume Down button for a few seconds.
  • While holding down Volume Down connect the micro USB cable to your smartphone.
  • Your phone should then load fastboot mode.
  • When that happens, release Volume Down.

There’s an alternative method that you can try if the above does not work for you. It is a bit more complicated and requires Android SDK tools.

From here on, I’ll assume that you already installed the SDK tools and have already enabled developer options on your LG V20.
