ok here is how u do it... dl pbp unpacker and extract from the 2.0 eboot and 2.01 eboot into diffrent folders... the open a hex editor and compare the diffrent data.psar (couse there is were all the firmware files is) now here is were the problem is.. it's only the first few lines that match and the rest is diffrence now.. that is beacuse there is an diffrent encryption in 2.01 so this was a good thought if it weren't for that stupid encryption that sony uses that is diffrent from f/w to f/w
