Little Phatty Stage I Stuck - Firmware Update?

Hi,

I was attempting to update the firmware on my 2008 Little Phatty Stage I today from 1.03 to the latest 3.2.

I followed the steps in the tutorial on the Moog website.

  1. Bootloader installer

This worked fine over MIDI. Went through all stages from STAGE 1 to STAGE 5 fine.

  1. Got to this screen:

Little Phatty, Boot v1.1
Checksum Failure, Erasing Flash…
Checking for USB Module
Please Send Firmware

  1. Started to upload the firmware:

I used Sysex and my M-Audio midi sport and it transferred the hex file but half way through said “failed”

  1. I switched off the LP and now it looks like it is in the dreaded ‘brick’ mode?

Have tried switching on and off and using Sysex to upload a couple of Hex versions I found on here.

Is there anything you can advise to help?
