I am searching for an answer to this question myself!
I tried the method described in this forum (using Bootloader, mtty, "s2d", ...), but after reinstalling the backup, the radio and protocol version remained unchanged!!! So I guess that this method does NOT save the radio and protocol ROM. It does save the ext ROM, though.

Can anybody provide a map of the magicians memory?? At which address is the radio stack? Can someone post a list of the Bootloader V1.00 commands?

Thanks!

Here you can find more information:

When using the bootloader:
Typing "d2s" saves the whole WinCE ROM and the extROM to the SD-Card.

As far as I figured out, the Radio-ROM is located at 0x60000000, although I did not try to restore the image over another radio version yet. But I made a backup of the first 3MB of a MDAc (with 1.11.00 radio) starting at 60000000 to an SD-Card and compared the contents to the 1.11.00 Radio_.nbf file, and to me it looks like I am right.

So I would make a full backup like this:
- Enter the bootloader
- connect device to PC with USB cable
- Start the mtty-program on your pc
- insert SD-Card (>=128MB)
- type "d2s 80000000 04000000" to backup OS, extROM and device version + type information (be careful when loading ROM to a different MDAc!) (or type only "d2s" to leave out device info)
- type "d2s 60000000 00300000 sd a" to append the Radio ROM to the Image on SD-Card
- now you have a complete backup on your SD-Card.

There are different ways to make memdumps of the device. I chose the one using the Bootloader.

I cannot (at the moment) give you a guarantee that the described method really works. But I am quite sure. You could try to backup only the Radio to the SD-Card using "d2s 60000000 00300000" (without the "sd a"), then upgrade the Radio to 1.11.00 using an official update, and afterwards restoring your old Radio ROM from the SD-Card.
If that works, the complete backup should also work, cause I already copied a ROM from one MDA to another this way ("d2s").
