---

Any boday tell me how to backup HD rom from device?Use backuptools can not backup.

Thanks yr help!

I use the spb backup software. works great.

With the backup tools mentioned above you can't extract the rom at all. There you need some specialized tools. Click here in order to get more details.

Here's how to do it - most tutorials miss important bits of information, so I'll post a detailed instruction here.

1. Download itsutils and copy them to a folder (in my case it's C:\itsutils)

2. Fire up the Windows command line window - Start, Run, cmd

3. Go to the itsutils folder by typing

cd c:\itsutils

4. View available partitions (not necessary, you can skip this step) with this command:

itsutils -l

You should get something like

457.50M (0x1c980000) FLASHDR
|           3.12M (0x31f000) Part00
|           4.25M (0x440000) Part01
|         126.38M (0x7e60000) Part02
|         323.75M (0x143c0000) Part03
  7.42G (0x1db000000) DSK7:
|           7.42G (0x1dac00000) Part00
STRG handles:
handle efea74fe  7.42G (0x1dac00000)
handle 4fd70f46323.75M (0x143c0000)
handle 2fe261f6126.38M (0x7e60000)
handle 6fe261d2  4.25M (0x440000)
handle 4fe26002  3.12M (0x31f000)
disk efea74fe

5. Check partition sizes (you can do this instead of the previous step):

c:\itsutils>pdocread -w -d FLASHDR -b 0x800 -p Part00 -t

You'll get

real nr of sectors: 1598  -   3.12Mbyte, 0x31f000

Repeat for other partitions:

c:\itsutils>pdocread -w -d FLASHDR -b 0x800 -p Part01 -t
real nr of sectors: 2176  -   4.25Mbyte, 0x440000
c:\itsutils>pdocread -w -d FLASHDR -b 0x800 -p Part02 -t
real nr of sectors: 64704  - 126.38Mbyte, 0x7e60000
c:\itsutils>pdocread -w -d FLASHDR -b 0x800 -p Part03 -t
real nr of sectors: 165760  - 323.75Mbyte, 0x143c0000

6. Dump the ROM now - you'll get it in parts. Make sure the sizes (bold) match the ones you got in the previous step!

pdocread -w -d FLASHDR -b 0x800 -p Part00 0 0x31f000 Part00.raw

pdocread -w -d FLASHDR -b 0x800 -p Part01 0 0x440000 Part01.raw

pdocread -w -d FLASHDR -b 0x800 -p Part02 0 0x7e60000 Part02.raw

pdocread -w -d FLASHDR -b 0x800 -p Part03 0 0x143c0000 Part03.raw

7. Put the parts in an archive and post here - that's it.

Many thanks for this usefull infos!

How can I make a flashable file from this 4 raw files?
(Sorry for this question, I'm not so expert in this theme.)

is this procedure all done on the handset or does it have to be connected via activesync?

via activesync

thanks for tha quick reply mate,
much appreciated,

To make a flashable ROM out of these files you'll need a kitchen.

BTW, I think that extracting the fourth part is not necessary, but this needs to be confirmed by someone more knowledgeable.

In general, I think instructions about such stuff should be in a sticky post in this forum, I find it strange that people ask users to upload their ROMs without explaining how to do it.
