Today I appear to have broken my Quad (engineering version HW v2.2) while installing the newer firmware. I think that the FPGA update got me because that update reports completed now that the Quad never completes boot-up (had to video the start-up screen and then frame step the video to find that very quick flash message “FPGA Update Successful”). With the previous versions you could always hold the right arrow key and power up to USB drive only, to revert back to previous software. After this problem, that USB drive only feature no longer works. So now that I am unable to access the USB drive, I am also unable to restore back to the previous version because I can’t change the files on the USB drive.
