Version 0.2.7:

  • Added local NP license handling.
  • Added option to override klicensee.
  • Added option to disable section skipping (in SELF generation).

Regarding the PS3 SCETool Scripts (linked above): This is a nice little set of batch scripts that someone made to work along side SCETool.

Use the GETSELFINFO.bat to figure out what version your EBOOT (my copy of Resistance 3 was ver. 3.65) is which helped explain why some EBOOTs couldn't be modified. Don't forget to grab the Conent ID if you're changing the EBOOT from an update.

Finally, in related news keperfear has made a [Register or Login to view links] stating that you will need to have at least .Net 3.0 Framework installed to use it.

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..
