Finally, in related PlayStation 3 hacking news pink1 has made available an R2R+Edat tool followed by a R2R+edat v1.0.1 update with details below, as follows:

Here is a tool I put together. It's pretty much rap2rif, rif2rap and an edat fix tool for C00 type demos. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

This is a small update to R2R+edat, it fixes edats being a byte short & should speed up pkg2edat a lot by only decrypting the first 5MB instead of the whole pkg. Put your act.dat & idps in the data folder and you're ready for rap2rif & rif2rap. To fix C00 type demos input a .pkg from a C00 demo or the PARAM.SFO and it will output the fixed .edat.

Finally, in related PS3 EDAT news from BuC (aka BuC-ShoTz 1-2013) comes some old EDAT SRC Codes as follows: going through old stuff on my pc, for learning purposes i suppose.

basically a payload like the one used in the 3.41 jailbreak (hermes) is loaded into stack overflow when the ps3 tries to read this the payload is loaded into memory and you get unsigned code execution. but the problem is that ps3 is using the stack and it copies something to it instead of reading first.

so the payload which has been loaded there is being over written before it has been read and is deleted so if you could somehow make the ps3 read from stack or load the payload just before the stack gets read the payload would be loaded and you have a new jailbreak.

i'm understanding it a bit more. the higher the lvl, the more security breaches needed because it'll allow it to be more open?

Generally, assuming that there is already a user mode exploit (think an exploit in a game), using this exploit will allow you to elevate permission to kernel level. The simplest way to think about it is the PSP exploits, and how multiple exploits were needed. Generally, of course!

if that was to me, it doesn't make sense.

eh, whatever. i know it's not exactly for me, i was just wondering the possibilities but i'm guessing it's not something easily explained in a sentence or two in laymen terms.

You don't need a lv1 exploit, it can glitch HTAB..
