Bad Elf Flex: Updating Firmware

Bad Elf Flex: Updating Firmware


Ready to upgrade your Flex to the NOV-2022 release? Just follow these steps:

  1. Upgrade the Bad Elf Flex app on your phone/tablet to version 1.2.1 or newer

  2. Download the latest firmware version from the table below, and upgrade your Flex using the USB drive.



The Bad Elf Flex firmware can be updated using a USB drive connected to the Bad Elf Flex using the supplied USB-OTG adapter.

Installation Steps

  1. Download the latest public firmware version (see table below) to your PC or Mac.
  2. ‚ÄčVerify the file name to ensure it ends in version "xxxx.bz5". Ex: flex_firmware_1.2.0.1208 (2).bz5 (wrong) -> flex_firmware_1.2.0.1208.bz5 (correct)
  3. Copy the file to any FAT-formatted USB drive, and cleanly unmount/eject the USB drive from your computer.
  4. Turn your Bad Elf Flex unit ON by holding the power button for 3-4 seconds, and wait until you see the main LCD screen (~30 seconds).
  5. Plug the USB drive into the supplied USB-OTG adapter cable.
  6. Plug the USB-OTG cable into the Mini-USB port on the back of your Bad Elf Flex.
  7. The left LED should light up purple, indicating the OTG cable was detected.
  8. The LCD screen will display a message indicating the USB Drive was detected.
  9. 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.  Be patient, this can take 1-5 minutes depending on the state of your Flex.
  10. When finished, you will hear 2 beeps, and the new firmware will automatically start. 
  11. You can check the new firmware version by navigating to Settings > Flex Info.
  12. You can safely disconnect the USB drive and USB-OTG adapter cable from the back of your Bad Elf Flex.
