Backup Windows CE on HP hx4700 PDA

Table of Contents

Objective

I "needed" (wanted) to backup the original Windows CE found on my hx4700 PDA before:

Not to search again, the procedure is described in this document.

Prerequisites

Here is what you need:

How to backup Windows CE

Do a backup using the HP provided application and put the backup file in a "safe" place because at the end of this procedure the iPAQ will perform a hard-reset.

Insert the SD card in the PDA.

Warning

Any content found on the SD card will be lost after executing this procedure!

Launch the HTC bootloader by holding Contacts + iTask + Reset until the "HP" logo is displayed in the middle of the iPAQ's screen.
On top of the iPAQ's screen should be displayed the string "serial".

Note

The screen is NOT backlit.

Connect the iPAQ's cradle to a Fedora Core 6 computer and put the iPAQ on the cradle.
Now on top of the iPAQ's screen should be displayed the string "usb" and, on the PC, should appear the /dev/ttyUSB0 device.
Configure minicom to use:

and start minicom.
You should get the USB> prompt.
Enter the bootloader's password: 
USB> password BOOTLOADER
and start the backup: 
USB> d2s
The d2s, or "Device to Storage", dumps the entire content of the PDA's flash to the SD card.

After the d2s completes successfully (you should have a message saying that) remove the PDA from the cradle, extract the SD card and press PDA's reset button.
The PDA will perform a hard-reset and returns to factory defaults.

Save the content of SD card

If you have a card reader connect it to the Fedora Core 6 PC and insert the SD card in it.
Presumming the SD card /dev/sdb execute: 

dd if=/dev/sdb of=wince-backup.image bs=130M count=1
to backup the SD card's content to the wince-backup.image file.
