Yesterday, in the middle of
The Intel Trinity, I pressed the page down button on my several-years-old Kindle Keyboard 3G, and nothing happened. It has frozen before, but this was the first time a hard reboot (holding the slide switch for 15+ seconds) didn't work, even after charging 16 hours or so.
So I downloaded the Kubrick 3.6 Live CD to debrick K3 devices ISO image, burned it onto a CD, and booted to a Ivy Bridge and, later, Sandy Bridge, PC. That went fine. Then I carefully followed the instructions regarding the power slider and the volume decrease button. Result: For at least fifteen minutes -- after which I give up -- the PC shows, in the middle of its screen, "Waiting for device" alternating with "Waiting for device ... ".
I've tried two different PC's, and two different USB cables, with the same results.
This Kindle has never been jailbroken, and any physical abuse is in the rather distant past.
I have another Kindle 3G in good working order except that the screen is cracked. So I have hardware repair options. But before I open the case to swap parts, what more (other than letting it charge for another night) should I try?
Thanks for all advice.
