Finishing flashing... Sending request 0x52 failed: Protocol error

Does anybody know how to fix this. I want to upgrade to diablo.

I think you should be ok now, it says each component has flashed. Try rebooting and see what happens.

Anyone have any thoughts on the error though?

Yes, I got that message as well, but the flash worked just fine.
