Have you tried following the directions given in the last sentence of that post?
The one about just exchanging the "OutFile (of) and the InFile (if)" argument parts of the dd commands in the posted script?

[blackwolf511]

No i hadn't thought about that.
How can this one be done?
I'm not so good on programming so i'd need some help.


I suppose you meant this:

dd if=/mnt/us/mmcblk0_7688.dmp of=/dev/mmcblk0 bs=512 count=7688
update_percent_complete 20
dd if=/mnt/us/mmcblk0p1.dmp of=/dev/mmcblk0p1
update_percent_complete 70
dd if=/mnt/us/mmcblk0p2.dmp of=/dev/mmcblk0p2
update_percent_complete 90
dd if=/mnt/us/mmcblk0p3.dmp of=/dev/mmcblk0p3

I suppose you meant this:

dd if=/mnt/us/mmcblk0_7688.dmp of=/dev/mmcblk0 bs=512 count=7688 ## This is the kernel and personal information - the personal information will be wrong if this *.dmp file was not made from your own device.  I.E: If this is not from your device, don't do this first command unless you want your DXG blacklisted.
dd if=/mnt/us/mmcblk0p1.dmp of=/dev/mmcblk0p1 bs=4096
dd if=/mnt/us/mmcblk0p2.dmp of=/dev/mmcblk0p2 bs=4096
dd if=/mnt/us/mmcblk0p3.dmp of=/dev/mmcblk0p3 bs=4096

ONE MORE TIME:
I do not think your DXG storage is partitioned in such a way that it will accept those commands and turn out correct !!!

Please, please, post the output of: cat /proc/partitions here **BEFORE** you write anything to your DXG *!!*

You are about to have a pile of spare DXG parts for sale.

I have no intention on doing anything on my own without some support from you or somebody more capable than me. I will try to find a way to post the output of: cat /proc/partitions over here but i got no rs232-ttl 1.8v cable so i dont know what to use.
Any advise? Could i use some kind of a shell if i put the dxg in recovery mode? Are all the partitions avaiable in recovery mode?

hi blackwolf511.
did could you repair it?

i have a problem like yours. i want to return back to 3.2.1 version but i unfortunately haven't success. can anyone help me?

[blackwolf511]

I managed to make a partition list. By using: usbNetwork, putty, TightVNC.
Here it is.


[root@kindle us]# cat /proc/partitions
major minor #blocks name

7 0 3510232 loop0
31 0 128 mtdblock0
31 1 3584 mtdblock1
31 2 32 mtdblock2
31 3 128 mtdblock3
31 4 3584 mtdblock4
31 5 64 mtdblock5
31 6 128 mtdblock6
31 7 24 mtdblock7
31 8 64 mtdblock8
179 0 3952640 mmcblk0
179 1 409624 mmcblk0p1
179 2 24576 mmcblk0p2
179 3 8192 mmcblk0p3
179 4 3510240 mmcblk0p4


What can i do now?

[blackwolf511]

i managed to do a backup of the:

mmcblk0.dmp 3,75 MB (3.936.256 bytes)
mmcblk0p1.dmp 400 MB (419.454.976 bytes)
mmcblk0p2.dmp 24,0 MB (25.165.824 bytes)
mmcblk0p3.dmp 8,00 MB (8.388.608 bytes)
rootfs.img [400 MB (419.454.976 bytes)]

by using this command on putty:

dd if=/dev/mmcblk0p1 of=/mnt/us/rootfs.img bs=1024

how can i convert it to update_rootfs.bin and restore my kindle?

thank you.

[Anaksagoras]

dear @blackwolf511
did you do it successfully?

[blackwolf511]

No i did not manage to do anything. I can't find a way to restore it.
Some help would be apreciated, now it stops at startup and i have to press 2-3 times Enter to make it continue loading and when it loads completely it does not let me create folders and is very unstable. battery dries out very fast... i dont know what to do.
Please help me.

[blackwolf511]

Now i have found 3 versions of "update_restore-os.bin" for the dxg

1) 246 MB (258.051.925 bytes)
2) 268 MB (281.178.704 bytes)
3) 252 MB (264.495.275 bytes)

No one of them works to restore my DXG.
It always gives to me error 0003.
Is there a way to make one of this work?
