A problem with pdocread

[jester_b84]

I am having a problem with pdocread.exe. Basically, I am trying to dump the ROM from my iPAQ hx2790 and I found the wiki on how to (http://wiki.xda-developers.com/index.php?pagename=Hermes_HowtoDumpRom) do it with the HTC Hermes. I started following the wiki which used pdocread.

Initially, it seemed to detect everything just fine using "pdocread -l":


E:\Downloaded\itsutils\build>pdocread -l
45.85M MSFlash
| 1.24M Part00
| 3.50M Part01
| 41.10M Part02

( 1.24M)


However, when I went to verify partition sizes using "pdocread -w -d....":


E:\Downloaded\itsutils\build>pdocread -w -d MSFlash -p Part00 -t

0 partitions, 0 binary partitions
customerid=00000000 uniqueid= 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

E:\Downloaded\itsutils\build>pdocread -w -d MSFlash -p Part01 -t

0 partitions, 0 binary partitions
customerid=00000000 uniqueid= 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
real nr of sectors: 1 - 512.00byte (0x200)

E:\Downloaded\itsutils\build>pdocread -w -d MSFlash -p Part02 -t

0 partitions, 0 binary partitions
customerid=00000000 uniqueid= 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
real nr of sectors: 1 - 512.00byte (0x200)


The offsets for all 3 partitions are detected as 0x200. Furthermore, they are all detected as 512 bytes.

If someone can tell me what I'm doing wrong, I'd greatly appreciate your help! :o

My goal is to extract MSFlash:Part02.

[jester_b84]

Hmm...nobody has any idea about this problem?

[hannip]

hmm, I just ran into this problem also. Maybe pdocread only works on FLASHDR devices?

[hannip]

It's not exactly clear to me, but from what I've observed it appears that if your rom is on a MSFlash device you need to use a tool that understands the MSFlash compression. You can use grab_it to create a bin of your rom followed by dumprom.exe to extract the rom sections.

If your rom is on a FLASHDR device you can use pdocread to extract each partition to a file. Then use the rdmsflsh.pl script to extract the files from the imgfs partition.

You can use pdocread -l to list your partitions and see with device your rom is on.

Do I have this right?

[jester_b84]

Thanks for your insight. I actually got the files in question from another ROM dump (the Treo 700 one) but I'm still interested in extracting the ROM from my device just as a challenge. I'll give it some further experimentation (after my CF card finishes formatting). In fact, I found that WM5torage has an option to export the Flash portion as a USB drive. I'll give it a try later...

You are using an outdated version of pdocread. please use the lates itsutils dated 2006.08.21.
Dump here pdocread -l return and the content of itsutils.log file in the root folder of your Pocket PC.

Oki

probably a little late response, but you can try removing the '-w' flag which makes pdocread use the disk API to access the device (this must be used in the Hermes becuase it doesn't have an m-systems disc-on-chip), but on other devices without the '-w' you can dump directly from the TFFS partition.

[jester_b84]

Thanks for the help guys, I've updated to the latest version of itsutils, unfortunately I am having the same problems. If anyone is interested, I have posted the dump of what's going on:

First, I issue a pdocread -l command:

Then, I issue a pdocread -w command:


C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -w -d MSFlash -p Part00 -t
real nr of sectors: 1 - 512.00byte (0x200)

C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -w -d MSFlash -p Part01 -t
real nr of sectors: 1 - 512.00byte (0x200)

C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -w -d MSFlash -p Part02 -t
real nr of sectors: 1 - 512.00byte (0x200)

and then, a pdocread without "-w"


C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -d MSFlash -p Part00 -t
real nr of sectors: 1 - 512.00byte (0x200)

C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -d MSFlash -p Part01 -t
real nr of sectors: 1 - 512.00byte (0x200)

C:\Documents and Settings\User\Desktop\itsutilsbin>pdocread -d MSFlash -p Part02 -t
real nr of sectors: 1 - 512.00byte (0x200)

It seems it still is not detecting the partitions...
I have also attached the itsutils.log file if anyone is interested.

By the way, there are some differences in the size of TFFS as I sent my device in for repair and they changed the motherboard (more RAM, less ROM for some reason).

--------

EDIT: If it makes any difference, it seems pdocread can detect TFFS correctly


E:\work\itsutilsbin>pdocread -d TFFS -p Part00 -t
real nr of sectors: 153946 - 75.17Mbyte (0x4b2b400)

E:\work\itsutilsbin>pdocread -w -d TFFS -p Part00 -t
real nr of sectors: 153908 - 75.15Mbyte (0x4b26800)

but fail to detect MSFlash and the storage cards (DSK1 and DSK2) correctly


E:\work\itsutilsbin>pdocread -w -d DSK1 -p Part00 -t
ERROR: ITLogDiskInfo - The device is not ready for use.

ERROR: ITTFFSGetInfo - The device is not ready for use.

WARNING: using default 512 bytes for sectorsize

E:\work\itsutilsbin>pdocread -d DSK1 -p Part00 -t

ERROR: ITTFFSGetInfo - The device is not ready for use.

WARNING: using default 512 bytes for sectorsize

Hmm...so only TFFS is detected correctly, all others fail.

From your itsutils.log:

STOREINFO dev='MSFlash' store='MSFLASH for STRATAFLASH' nsect=2dd9 bpsect=1000 free=0 maxpartsize=0

It means the block size is 0x1000 (4096 bytes).
So you need to add a parameter "-b 0x1000", that is:

pdocread -w -d MSFlash -p Part02 -b 0x1000 -t

I' have the same error!.. i'll try pdocread and i'll post log
here there is my 3d http://forum.xda-developers.com/showthread.php?t=393371&page=2

[L3D'83]

i change the version of itsutils now is 2006 08 21 and the log is that

[chuckbert]

ok, i almost expected something like this...

STOREINFO dev='MSFLASH' store='External Storage' nsect=fc00 bpsect=800 free=0 maxpartsize=0

this is the same like on my daxian!

try this:

pdocread -w -d MSFLASH -p Part02 -b 0x800 -t

i bet it´ll work for you!

[L3D'83]

yes i think that .. i tyed and it WORK!!! ..
ok Now i dump the :
Part00
Part01
Part02
Part03

i extract part02 and i see all wm6 files eith this procedure:

C:\ROM>prepare_imgfs.exe Part02.raw -nosplit

C:\ROM>C:\ROM>viewimgfs.exe imgfs_raw_data.bin

C:\ROM>buildimgfs.exe


:D
but ... i'd like to see the versionf of my chinese Elf , the radio version and the other information..

because i want to update the rom beacuse the signal of the line is very low (vodafone) some one can help me ? :

[satru]

deleted all
