HT-E6750W Firmware downgrade/patch

[GTK]

Hey,
Got my HT-E6750W, and my goal is to get rid of cinavia.
I Tried the DNS trick and all i got was "There are no new updates for you at the moment"
Model Code: HT-E6730Series_SQ
Software version : HTB-E55000MAB-2006.1

According to Samsung my latest official Firmware version is
SWU_B-FIRHT7MAC_002010_I03_ES000KS000RS000_130430
(This is not my version but a newer one, I'm on version 2006 and this is version 2010).

Update:
New Firmware released by Samsung
SWU_B-FIRHT7MAC_002011_I03_ES000KS000RS000_130614

Any way i can downgrade/patch the firmware so i can to the exeDSP patch?
Should i update first to the latest Samsung Firmware version?

Thanks.

I think B-FIRHT7MAC is not supported. Only firmwares listed here are supported. No requests for new firmwares accepted. Sorry. This is experimental feature and it works now "as is".
