What a pity! Please, more details...

I'm run the hpRUU.exe from dir TMOBILERST.zip with changed iPAQROM.nbf. After detecting my PDA, program say:
"Incorrect device SKU! Update cannot continue.
Current information about you iPAQ Pocket PC:
Model ID: HP iPAQ h6340
ROM Version: 1.11.10 ENG
Language: English
This upgrade is for:
Model ID: HP iPAQ h631x
ROM Version: 1.0.6.8
Language: English"

It's a sad truth...

For dmc874: Dave, I'm find this resolve many time ago. Give me hope...
