How to update firmware on a Gadget II stuck in bootloader mode

Issue

I'm trying to update the firmware on my Gadget II using the instructions found in the How to update Gadget IO firmware on an Eos Family console post, but it tells me the update has failed. The Gadget II is listed as Bootloader in the Detected Modules section. How do I resolve this issue?

Explanation of Issue & Solution

A Gadget II stuck in bootloader mode is typically the result of a failed update. This mode means the unit is ready to take firmware, but it must be updated through an alternative method outlined below:

  1. On a Windows PC with ETCnomad installed, open up Windows Explorer (aka Computer or This PC depending on the Windows version)
  2. Confirm there is a Bootloader drive listed. The drive letter will vary depending on how many other drives exist on your PC
  3. Navigate to C:\etc\nodesbin
  4. Right-click on the latest version of Gadget II firmware and choose Copy. At the time of this writing the file name is "14d5.0114_Gadget_II_v1.1.0.9.0.4.S19"
  5. Open the Bootloader drive and Paste this file to it
  6. Unplug your Gadget II, and then replug to power cycle the unit
  7. Open ETCnomad, and go to Settings > Maintenance, and confirm the Gadget II shows up in Detected Modules. If so the unit is good to go. If not, please contact ETC Technical Services.
