Force VOXL 2 into Fastboot

Overview

This procedure is for use if the normal update procedure above is not working.

Video

Procedure

  • Unplug VOXL 2 from power
  • Unplug VOXL 2 from USBC
  • Using something soft like a BBQ skewer or toothpick, press and hold the momentary button SW1 down, as shown in this image:

m0054-fastboot

  • While holding SW1 down, power on VOXL 2
  • Keep holding SW1 down for about 5 seconds and then let go
  • Attach VOXL 2 to USBC connected to host computer
  • Run the fastboot devices command and verify the device is showing up
❯ fastboot devices
f8bb8d44	fastboot
  • Now, you should be able to proceed with the ./install.sh command from the Platform Release zip file.
