After many years of fine service, I managed to erase the Atmel proprietary bootloader (AVRBLDR) on my JTAGICE mkII. I know for a fact the hardware itself is perfectly fine.
My attempts to contact Atmel customer support for help culminated in a loop of being asked to contact the group where I started after about a month of back-and-forth. They were all very un-helpful at best.
I found a couple of other posts from people with the same problem, but no one ever posted back with any solution.
In the meantime, to get on with work I purchased another mkII, but it seems a shame to toss the old one in the trash just because the bootloader is gone.
Does anyone know a way to get this back to "factory fresh" condition?
