HT-EM 45 firmware 1011 please help

[him099]

I just purchased Samsung's HT-EM45 surround sound system. Its running 1011 firmware which is infected.Im trying to downgrade firmware, Ive tried the DNS trick(which has worked like a charm in the past) but the upgrade wont take on this new HT-EM45. I can download the file just fine, but when i hit update, it reverts itself to 1011. Please help
