Okay...

Found the ROM on the HP site (SP23661) followed the set up instructions from your link.

Got the Ipaq into SERIAL mode

Connected it to the cradle

Ran the UpgradeUT.exe

It couldnt identify it - "error 116 Ipaq Identification Error" OR after performing a normal reset says "error 101 connection error"
Is there any way of directly addressing the Ipaq once it's in SERIAL mode - perhaps directly installing the "NK_Wisr111_00WWE_NBT.nbf" ROM image?

Did you get it into the Parrot bootloader mode?

Erm... I got it into the SERIAL/USB mode if thats what you mean. I pressed the on/off, button 2 and reset.

But the exe did not find the Ipaq

I've found a copy of MTTY but dont know what to do with it

Okay - we have some progress, the MTTY rom installer will map the device memory! But when I try to use the LNB command it tells me (in odd english) "this application only deal with absolutely image file". So what to do now, I do not know.

HHHHEEEEELLLLPPPPPP

You can find a ROM on the internet somewhere that isn't an EXE. However, if you look around your computer, you should find the one extracted from the .exe file and copy it over manually. Don't ask me how you go about doing that, though...
