My fos/4 Panel is in a Bootloop After Trying to Update Firmware

Symptoms/Issue

Trying to Update your fos/4 fixture either via USB or Updaterator, and the UI just cycles

Description/Explanation of Issue

This is possibly an internal bootloader issue. 

Fix/Solution

With your firmware bundle file (bundle.bun) on the root of a USB drive, power on the fixture while holding the ‘Mode’ and ‘Menu’ buttons.

The fixture will then default and load the bundle from the root of the USB stick.

Once loaded and running, the fixture may have a bundle error present. To fix this, run the upgrade again using the menu option.
