Sr-5000HD

Hi folks,
I got new Receiver SR-5000HD.
In the shop they told me its very good receiver but when I got back home, I see that this receiver has no company name or site where we can update it!!!!
I couldnt restore it back

how I can update it to new firmware?

Also this receiver has internet. For what I can use it?
Is this to open scrambled channels?

Best regards.

Flashing problem

Thanks for ur valuable Support.
Actually I was upgrading the receiver from a file I got from here
( BlackBar777_F012_1011_me-b_1t_sr5K-7K_wifi_yt.abs ).
Everything went fine.
I got different name for the receiver but everything went fine.
I looked more deeply over this useful forum, I found this file: 5000HD_wifi_yt11112012

I tried to upgrade using this file then receiver hanged for almost 5 min's.
I switched OFF then ON but its not starting at all

Is there a way to drop the software into the flash through serial Port?

What could be the easiest way to get it back to life?

Thanks and regards,
Rabih.
