Summary of the SD card ROM backup/update method

---

While a lot has been written, the following should provide an easy-to-follow guide:

Preparation:
1. A torch (read on and you will know why)
2. 256M SD card
3. Download ntrw.exe, romupdate.exe, hexedfull.exe from the ftp of this forum to c:\ and install hex editor
4. Download the appropriate ROM file (hereafter referred to as "newrom.nb1").
5. Cancel USB in ActiveSync
6. Use Sprite Backup to backup your ppc

Backup original ROM:
1. Put pocket pc into the boot loader mode (hold both on/off and camera buttons at the same time while resetting).
2. Insert empty SD card.
3. Connect pocket pc to pc through USB.
4. Run romupdate.exe on pc.
5. Select “\\.\WCEUSBSH001” in port settings. In the popup windows, enter “d2s” and press enter.
6. Don’t get panic to see the pocket pc screen goes dark. Use your torch and you will see the download percentage. Wait until it reaches 100% and shows “CheckSum is OK!”.
7. Insert SD card into card reader of the pc. Ignore the “format SD card” message and click “No”.
8. Run “command” to go into DOS prompt and change to root directory (cd c:\). Enter “ntrw read oldrom.nb1 s:” where s is the drive of your SD card.
9. Ignore the “Data error <cyclic redundancy check>” message. You should save another copy of this important rom file “oldrom.nb1”.

Change header of newrom.nb1:
1. Right click on oldrom.nb1 to open hex editor. Copy the first 416 bytes.
2. Open the downloaded newrom.nb1 file and overwrite the first 416 bytes with those of the old rom.
3. Save the edited newrom.nb1. You may save another copy of this important file.
4. Go to the command prompt and enter “ntrw write newrom.nb1 s:” to write it to the SD card. Ignore the error message “The parameter is incorrect”.

Update the ROM:
1. Insert SD card into pocket pc and put it to boot loader mode again (on/off + camera + reset). Use you torch to check the dark screen.
2. When it shows “Press Power to flash”, press the on/off button. Wait until it reaches 100% and ignore the message “Download Fail - CheckSum Fail”
3. Soft reset your pocket pc.
4. You may have to reinstall your software, unless you are familiar with the advanced features of Sprite Backup.

Ask you a question.
Does it backup 3 parts of rom (OS rom, extended rom and Radio rom)?

I am trying to backup my old Qtek Rom so I can install an update. I follow the steps to perfection..

The file created by ntrw is 999Mb big and at the end of the file I get an error stating that "parameters are incorrect"

Does this mean that the backup was not done successfully?

Why is the file so large?

Thanks for your help

ntrw get image SD card. Use SD card 256 Mb.

SD Card update problem

---

Hi I used ntrw.exe to backup my original rom to an SD card. It all went ok and I was able to clear the SD, write the rom back on the SD and put it in my M500. Normally I got a menu to press the power button to flash the rom to my phone, but now whatever I do I can't get the menu back. I won't get the option "Press power button" to flash. What I also see is that somethimes when I put the SD back in my laptop it is totaly empty. Normaly it would ask me if I want to format the SD because it can't be read. Can anybody help??

Thanks!

Dear All,

this is my first time to this site.

Could you please send me the download links for the files that are necessary (or the files themeselves) to backup the ROM (ntrw.exe, romupdate.exe, hexedfull.exe )

Thanks a million.
Will

i found this http://www.ccoo.net/MDAFlash/ntrw.exe

Thank you for this wonderful guide !!!

I am trying to backup my I-Mate JAM's ROM with a 256 MB SD card. However I have a similiar problem where when the ntrw.exe completed with the same "parameters are incorrect" error. The created ROM image is about 247,040 KB.

Is this correct? I did make sure the SD card is empty before the backup process (by deleteing everyfile on it), or should I use some proper method to ensure the SD card is actually completely empty?

Thanks in advance for any help!

Mine came up with that every time, but worked ok. I am trying to do the Anasky ROM update to my magician, and the backup i made of the original rom was fine to restore, even though i got that error.
