HT-E4500 custom firmware?

[buckguy22]

I just bought a HT-E4500 the other day, which has the B-FIRHT7WWC firmware on it. I was pretty bummed to find out that it has Cinavia with it. I've read up on a few things, and did the DNS trick to download the old firmware, but no luck in disabling Cinavia. I was reading about decrypting the firmware on the wiki, and disabling it that way, but I'm not 100% sure how that works. Anyone have any experience with this firmware at all? Mainly all I want it to get rid of Cinavia if possible.

I need downgrade the firmware of this model to remove cinavis, please add this model in your server, thanks
