Tom, following our conversation yesterday Xmodem is a very old simple file transfer system with Linux: lrzsz http://freecode.com/projects/lrzsz
simple checksumming of transfered packets. https://en.wikipedia.org/wiki/XMODEM

Clients are still available for Mac, Windows and Linux platforms.

Mac: http://download.cnet.com/Apple-XModem-Tool/3000-2109_4-10006312.html

Microsoft: Extraputty http://www.extraputty.com/download.php

Linux: lrzsz http://freecode.com/projects/lrzsz

Hope this might (?) help you recover the lost OS!

I couldn’t get XModem to work so I tried something else…

Goes from the bootloader / recovery mode to the secondary image

copy flash flash primary

Moves the flash from secondary to primary

boot

Reboots the switch which then works fine again! Yay for deleting the primary image on the switch not being the death nail!
