hi knc1,
I'll be in the fight if possible, somehow trashed the serial jailbreak chance (ripped off the tx line...
), so now only with software...
Already searched the main partition for some trick, and will continue. Discover how to get the usb downloader mode would be great too, perhaps I'll open the voyage again for this.
I think possible lab26 used the sense pin of the usb port, reading the datasheet it is clear that only a external device could tie the boot pin in the proper state at reset.
Or there is a retriggerable monostable multivibrator secured by a watchdog issued by software. If so a way to freeze the kindle could give way.
