I have a K4 bricked with a frozen screen.
This picture shows about how far I have gotten.
I have successfully loaded Kindle Fastboot with MfgTool and I have HID complaint device int Device Manager.
Looking at the guide here http://www.mediafire.com/view/?xrn3v3ln6cn2n75
It looks like I should next update the device driver to Kindle-Fastboot.inf but when I try to do that windows xp says that it does not contain information about my hardware.
I don't know where to go from here.
