[Q] error into downloading mode (Samsung Galaxy s duos 2 "GT-S7582") topic

Hello

I have a phone type : Samsung Galaxy S Duos 2 "GT-S7582"

My Device looks like a Locked, I can not control device settings
Such as: i can't transfer of files from the phone memory to the memory card, watch RAM and closing programs, update the system via Wi-Fi, access to factory Reset, access to the download mode.

The biggest problem, the computer can identify device, but Keys program can not identify device, and connect the device to the computer tells me, knowing that he is connected to the computer.

I experience all the solutions in over the site, I did not find a solution to this problem !!
When I use "volume up button + Home button + power button" to into Factory reset
i see "Factory Mode" But for TESTING not for reset the phone

"( Image for clarification )"


I said to myself, maybe I need to restore factory settings, but unfortunately this is not a solution to the problem, because i work to restore factory settings through the device settings and did not solve the problem.

So I've downloaded the Rom official of the device from the site "SamMobile"
and I've downloaded "Odin Program" For the installation of the device rum
And When i want to enter "downloading mode" so I could not.
The program Odin does not recognize the device because of not being able to access "Downloading Mode" like Keys program even though The computer recognizes the device and I can access files across computer.
