a great deal of knowledge that you don't possess but you have to learn somewhere. Try downloading the 150 poc source code, so you can understand how the firmare is altered to load plugins and execute no-kxploit eboots and hide corrupt icons . 150 also mplements a recovery menu.

Look for how he implements the patches and if the source code is beyond you then you need to learn c (in depth).

another thing you could do is write a couple of small kernel prx's then reverse them with prxtool. examining the c source and asm side by side to try and understand whats going on

another thing how, for example did he get the arguments to vshman,prx? think about it and it should become obvious

remember until the slim came out all cfw were based on 150. the information might seem obsolete but it could be used to write an upto date phat cfw firmware

btw decryting a firmware (probably with the new psardumper thats floating about) makes you a hacker-tool user, not a hacker
