Make sure your Bad Elf Flex is running firmware version 1.0.19 or newer. If not, update your firmware first.

The left LED should illuminate with a purple status indication, indicating the OTG cable was detected.
The LCD screen will display a message indicating the USB Drive was detected.
Within a few seconds, the Flex will start the update process. You will usually see the all the LEDs turn purple during the update, and the screen will display a "Shutting down..." or "Updating firmware..." message.
The GEOID packages can take 1-3 minutes to install depending on the speed of your USB drive. You may or may not see any progress indication. Be patient!
When finished, you will hear 2 beeps, and the firmware will automatically restart.
