Not exactly, it's actually holding down buttons and strumming alot. And it'll just crash dump ONCE and continue and not crash dump again until you turn off your development kit or exit the executable. Works fine. Try removing All Media checks, making it work for All Regions, Uncompressed, Unencrypted. That's what I did. I'm on 8276, though it does work on 7978 for sure.
Not entirely true, you just have to be smarter than the update. ;-) Run the update once with the HDD removed. After that completes, you can plug HDD back in and run update a second time and lo and behold you can now uncheck the box to format HDD. :clap:
