GSM-Forum - Final solution: i8700 not retail.

Hello all,

I'm having some problems with my SAMSUNG OMNIA 7 device. After spending many hours on xda dev and others specialistic sites i didn't find an answer to my questions:
1. Is possible to flash a not retail device?
2. What exacly means a "not retail"? I bought it from **** seller, he said that it was a demo phone
3. What means mojobld?

Ok now i can tell You what i know...

OS version: 6541.WM7_7.0_Ship(mojobld).20100817-1435
Firmware: 2424.10.8.8
Hardware: 3.15.0.4
Bootloader version: 4.8.2.7
Chip SOC version: 0.36.2.0

ZUNE doesn't see my phone as it should
It says that my phone is update
The Device_Update_Support_Tool_for_OMNIA7_KC3_Ver1.2 gives me an error, it says that this device is not supported
When i'm trying to do a hard nodo update it doesn't work (switching off internet connection) - it shows - system is update
I havnig all usb drivers from Samsung
I have also installed a Windows Phone SDK
I downloaded a many roms from internet. I was using many different versions of WP7 downloader. It never works as it should:
"binary error..."
"not retail device..."
and the last one (when using modified version 7.41):
Detect COM3 Port
[Channel 0] Confirm Model Name
[Channel 0] FLASH UNLOCK
[Channel 0] FLASH UNLOCK Success!!!
[Channel 0] Send Partition Table
[Channel 0] Partition Table is correct
[Channel 0] Erase MIBIB Region
[Channel 0] Write MIBIB Data

and then it stops on MIBIB Downloading... 90%

when I'm trying to use a DFT Rainbow it gives me:

[Error Description]:

[Info]: USBWorkDMLI_SAM.cpp (206)

The download mode works OK, there is no problem with booting into it.

I really don't know what to do. Please help

PS. Oh and it looks like typical i8700. There is no a prototype motherboard. It has a serial number, imei and other information under battery cover.
