There is something certainly wrong inside that eMMC flash chip.
This is also probably why you had trouble transferring the file intact - that shouldn't have happened either.

Thanks for your help - we now have some new tools and knowledge to deal with this sort of problem.
Something that will be showing up more and more often as the Kindles age. |
In the function WriteBlock, just before the: set $($dd line, add:
echo "Writing block: $BLK"
Then run the same command more than once, see if it makes any progress (the already programmed blocks will be skipped).
You can also disable that 'info' message using the command mentioned in the message.
