PS3 (Doubt) Is there an known reason why it's not possible to do flash patching for 3.56+ PS3 Models?

That's the question

Because we don't know how to do it. After 3.56, Sony fixed that flaw that we can access lower hardware levels. @zecoxao and many PS3 scene devs tried many things over years and they cannot find any hardware and software flaws for usable for exploiting and accessing lower levels than LV2. Also finding LV2 exploit required many years and progressive hardwork. At least we can run homebrews on 3.55+ consoles. @zecoxao still tries but i am not sure he can find anything or not. Still i am grateful for PS3 scene devs that they managed develop exploits and homebrews for uncommon architecture.

sony changed the boot loader and fixed the encryption error.

Consoles manufactured before fw 3.56/3.60 had a flaw in the encryption keys, s#ny generated and used keys that were vulnerable and "easily" broken, consequently devs were able to work them out and defeat the supposedly secure boot process, thus allowing the use of CFWs.

The encryption keys they used after that are a lot more difficult to break, bruteforcing them is out of the question and so far nobody has been able to find an exploit in the first stages of the boot process that could allow us to create CFWs on post 3.56 consoles.

There are still ongoing efforts by a handful of devs to hack that new boot process but for the time being there's no guarantee those efforts will yield the results and data required to finally allow CFWs on all 3xxx/4xxx consoles.
