Flash a non Retail Omnia 7

hi

omnia 7,when i putt in download mode,appears on the screen ,a phone a a pc,nothing write,like download mode.

Hello guys, this is my first post on xda dev so...I want to say hello;-)

I know that this topic is old but nobody resolved the problem.

Just about few days ago I also purchased a Samsung Omnia 7 and when I'am trying to flash it appears: This is not a retail Device :/ or something like that. I thing that You know what I mean.

Is there any way to have a Mango Refresh 7.5 on this phone? The DFT doesn't work, it gives me a USB error USBWorkDMLI_SAM.cpp (206), but i have alredy installed all useful drivers:-/

The Downloader gives me a info - non retail device or Flash Lock [0].

I have to say that i like this phone, but it is unuseful without a 7.5. Can You help me guys?

Here are some informations about software:
