Kindle paperwhite doesn't upgrade software

[Whitefox]

I tried the script on the kindle, it seems it works

[root@kindle root]# time ./copycmp.sh /dev/mmcblk0p2 /mnt/us/blk0p2.img

Now should I try to do something like this?

./copycmp.sh /mnt/us/rootfs.img /dev/mmcblk0p1

and check it with

./dc3dd if=/mnt/us/rootfs.img hof=/dev/mmcblk0p1 hash=sha1 ssz=4096 nwspc=on verb=on

correct?

I got some problem coping the rootfs.img with usb, the file copied had a different md5 hash, so I had to split in a bunch of chunks, copy them(one at time), and join them using the serial console

Yes

Checking is optional - that was just to confirm script operation and demo dc3dd

ah - now that might be part of the problem.

Sorry I haven't gotten the HowTo written yet -
Have to get my PW-3 re-assembled.

dc3dd will do the splitting into chunks for you (dc3dd --help).
the one in x86/dc3dd might run on 32bit linux else install the copy from your linux distribution.

Ok, I think the memory is gone

But informative.

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.
