I bought a Cobra ODE when they first came out hoping it would work as reported. Always work no matter the firmware version so I could keep my PS3 up to date after a friend updated it and ruined my jailbreak! I was on 4.5 when it was installed and it works great. I think I updated it once maybe twice with patches they put out for the ODE. It's now been a year or more and I spent a lot of it ignoring my ps3 but it seems we are up to 4.7. Luckily I looked it up before updating to be sure and I saw on the Cobra site they were no longer supporting some of the Fat's and mines a CECHA01. Now even out side of that I read it's more complicated to update any ps3 to even 4.66. So I need to know what I've missed, what's a DMC... do I need one, can I even use one with my PS3 and or can anyone tell me a way I can get Netflix to ignore PSN because the new updated Netflix app it doesn't work with the Router block/proxy method and really it's the only reason I want to update because I don't game online. I don't need PSN I just need a PS3 that works with my ODE because thats the main reason/way I use it. I'm just hopping I can use it for netflix again to!
