I really wish we could figure out a way to force touch only devices it into fastboot or usb downloaded mode like the old ones that had a button.
I'm not familiar with the repair process of devices like this, but if third party refurbishers ( or whomever gets the contract to refubish them ) are able to re-install official first boot firmware, they have to have a way to get it installed. So I wonder if they have real hardware kits that hook up to the labelled "usb boot" pins on the motherboard, or they do it another way.
