As I posted here:
[Kindle Touch] Localization
I've also the problem that my Touch device does not boot any longer
And I also tried to put the usbnet_1.1 bundle to the USB drive and (of course) it showed me the "UPDATE ERROR: 3".
Do you see any chance to make my device working again without serial interface?
Maybe any update bundle which enables to reset it to factory settings?
Or any other suggestions how can enable usb- or WiFi-networking to go to the device and resolve the problem directly on the device?
BTW, I think it does not to execute the runme.sh script - otherwise this would be a solution...
