There's lots of info.
It's not a matter of breaking the OFW, it's a matter of getting a PS3 that hasn't been hacked that verifies the signature of a signed firmware.
Any CFW will not have a signature from Sony so it won't install.
The signature isn't in the firmware, only a public key that verifies it is signed by who it says it is.
The signing key can't be calculated with the public key used to verify it is what it says it is.
So, not possible to install.
We have signing keys for firmware up to 3.55 because Sony made a mistake that has since been fixed - PERMANENTLY.
This is why we can install CFW on a 3.55 PS3, because we have the signing key that it will accept and can trick the PS3 into thinking it is a genuine Sony firmware. After this firmware version, the signing key changed and we - EVEN NOW - cannot calculate it.
We can decrypt the firmware, but a console on OFW is still locked and expects the signing present that we don't - and never will have.
There is NO hope so don't go further with this, it's based on basic cryptography principles created over 20 years ago that to this day have not been broken. If you're interested in satisfying your doubt instead of accepting my answer, look up the term "private public key encryption" on google. Please search first in future because this has been the most asked question in the past 2 months or so.
