Try another usb dongle. Patching does not influence to upgrade/downgrade function.

Yes jusso - operation downgrade 2005 to 2004.1 succesfully end .
But how do upgrade 2004.1 to 3001.1 ?

I see. To be on very latest firmware you have to install two firmwares.
Step1( T-CHL7DEUC 3000.2) and after that step2 (T-CHL7DEUC 3001.1).

I see. To be on very latest firmware you have to install two steps firmwares. Step1 and step2.

Are you sure it will give him Ifficial firmware ?

[juusso]

Yes, exactly that one

[wlodarek1]

Thank you all for your help .
I install STEP1 and then STEP2 section of firmware and instalation ended succesfull
But 1 remained a problem ; tv have not a internet connection .
When I select "@internet tv" I see only response ;

service not supported

Why is it like that

[juusso]

Samsung stopped to support B/C series tvs with old fashion internet@tv. I guess.
