For most users, we recommend using the Bad Elf GPS App as the method of updating the firmware on your Bad Elf Pro+. There are a number of additional safety measures built into the process found in our app to ensure success. This method of updating requires the use of a Mac or PC.
Download this file: https://epo.bad-elf.com/fw/dfu/BEGPS-2300-v2.1.60.dfu.bin
Rename the downloaded file from BEGPS-2300-v2.1.60.dfu.bin to firmware.bin
With the power OFF on the Bad Elf GPS Pro+, connect the Elf to your Mac or PC with the supplied USB Cable.
You will be prompted to Tap the GPS (bottom) button to enter USB Drive mode.
After tapping the bottom button give the process a minute for the Elf to appear as a drive in Finder or Explorer.
Once you are able to access the Elf as a Drive, copy the renamed file firmware.bin to the root directory of the Bad Elf GPS Pro+.
When the transfer of firmware.bin to the Bad Elf GPS Pro+ is complete. Unplug the USB from the back of the Pro+ to exit USB Drive mode.
Now plug the USB back in and tap the bottom button to enter USB Drive mode.
Upon entering USB Drive mode on this subsequent attempt, you should see small text on the screen that a firmware file was found.
As soon as the firmware file is unpacked you will be prompted in large text to Press Power Button to Finish Firmware Update.
Press the power button and the process will shortly be finalized, the Elf will power down and then power back up.
The firmware version running on the Elf can be found on the startup screen in the text to the right.
