Accidental Update 4.41

Hi,

I had just setup Netflix to work on the PS3 (from Australia) and left it for my wife to enjoy whilst we had a sneaky boys trip in Melbourne for the footy.

Got back, and whilst I was away she had updated the PS3 to OFW4.41 as it said to - black screen, etc. but I have now sorted that.

Is their anyway to downgrade (without flasher), or install 4.40 Rogero back on the PS3?

Cheers,
MP
