I just had Chesh post my video in a closed thread so that people could realise that there isnt a solution yet.
Some one even watched it and asked...
as to which my reply was...
Have you tried just renaming 3.55 to 3.56? if it just compares names.
Trust me if it was as easy as these solutions we have been coming up with then we would of cracked it by now..
The .PUP files dont have the FW values like 3.56 stored in the file name.. to mod the actuall number value of the .PUP file you would need to open the .PUP file and modify the code inside to change the value. I have no idea how this is done and so therefore cant do that.
The other main reason you cant load up any FW lower than 3.56 is because sony added a new Key to the new FW. This eans that if the old FW does not have this new Key, the PS3 will know its not been signed by sony.

Conclusion: Wait for someone to bring out a CFW that actually works and not fake like all the you tube vids out there, and in the mean time stop complaining that there isn't a solution and just wait.
We all trust what we can see, but are always unsure if we cant see.
