It sounds like this might have been linux. The linux on the iPAQ has a tendency to not restart properly after a shutdown like that.
Performing a hard reset (which is what you do when you put the pen in the hole, not a soft reset) while holding down the speaker button is
designed to bring up the bootloader.

I'll assume you already realise that NK_Mac18700GER.nbr is the German version of WinCE...
It sounds like you forgot to remove the Parrot bootloader . Not removing the Parrot section of the WinCE image (the next 256K of the image
after the first 32 bytes have been removed) and flashing starting at 0x40000 would offset all the WinCE code. I understand that WinCE has its
addresses hard-coded so that is probably why it is not working.
Follow the instructions on:
http://www.handhelds.org/z/wiki/Restoring%20Windows%20CE%20from%20the%20Compaq%20iPAQ%20Update
Then, if you want to remove the bootloader, do "load bootloader" and send parrot.bin. This will restore your iPAQ to the state that it would
have been in if WinCE had been factory-loaded.
You will need a copy of dd.exe (unless you have linux...). If you can't find one, email me back and I will send you one.
Good luck.
