No Boot: Pan lights moving back and forth

Hi all,
Following directions else where in the forum, trying to force a firmware update and now all I get is Pan lights moving back and forth.

No results with:

  • Press and hold the touch screen Reset and Setup keys together and then power up the mixer (these keys are the located to the left and right of the touch screen encoder button). Keep the keys pressed for at least 5 seconds while the mixer boots. Release the keys.
  • Put USB key with k\latest firmware into the USB-A slot. Hold the USB (above preamp) and HPF in buttons down as you power up. This should invoke the bootloader to look for a new firmware image on a USB key and force an update.

Suggestions?

A&E offered this, and it worked:

Are you attempting the update from a Mac or PC?

If it’s a Mac- you will need to manually rename the Firmware file as per these instructions: https://support.allen-heath.com/hc/en-gb/articles/27372432963729-Issues-when-copying-firmware-files-to-a-USB-drive-using-macOS

They maybe should create a proper download for Macs?
