I've made a level shifter as described here :

Sorry for misusing the sdcard. I've ment the internal flash, of course.
I don't have a scope here to check why isn't the transmit part working, but I might bring it to work to check it.
Meanwhile, I've installed the custom kernel from here :
and did manage to connect with a serial over usb console.
The problem is that this happens right at the begiining, before any blocks being mounted.
Once i issue the start of the kindle os, as described also there, I can't do much of a thing.
This would be useful after the kindle has booted to have at least the partitions mounted.
You say that if i fill with 0s those memory areas, the kindle will build it's partitions ?
I could try that. I will try to create an img filled with 0s and then flash it with k3flasher from the right address.. that might do the trick, i hope..
I don't want to give up on fixing it
I've already changed a display for it and bought all the parts for the serial cable, so a new one might have been cheaper
So any ideas are highly appreciated.
Ah, phooey - - "I installed the custom kernel ...."
Sorry, I never dug into that custom kernel to see what, if any, changes where made to its initramfs system (the one responsible for re-building /var/local (mmcblk0p3) and /mnt/usr (mmcblk0p4) file systems).
So all I can say is: A stock kernel will detect and rebuild...
