Below are the changes, as follows:

Version 1.20 Changelog:

  • made minor alterations to code.
  • now after entering title id it asks for the games title then automatically adds it to the param.sfo.
  • added support for creating a ps2 classic dex ISO.BIN.ENC.

Version 1.21 Changelog: Hey guys here is v1.21 test version i have released which has been tested on windows 8 x86 and x64 also windows vista x64 so hopefully it will work for everyone. also i have changed the logo for one created by brakk3n so let me know what you think i have also altered quite a bit of code for example now instead of keep extracting the files if it detects the folders it wont extract them again. also if a file doesn't exist its gonna use it will unzip it so hopefully this will not only increase the speed but reduce errors. i have also added support for resigning game updates that contain self files but i cannot test it since i'm on 4.30.2 and it would most likely work on it.. especially if its resigning to lower CFW so that will need testing, so let me know if this works for you thanks.

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..

Following up on his PS3 SCETool update and PS3 Dump_Rootkey code, today Sony PlayStation 3 hacker Naehrwert has posted some details on exploiting the PlayStation 3 lv2_kernel and has made available a sample 3.41 implementation below.

To quote from his blog: Exploiting (?) lv2

A long while ago KaKaRoTo pointed me to a stack overflow he found while reversing lv2_kernel. But there are two problems:

1. The vulnerability is in a protected syscall (the SELF calling it got to have the 0x40... control flags set). So you’d first need to find a suitable usermode exploit (don’t ask us), that gives you code execution with the right privileges.

2. The payload data is copied to lv2 heap first and the function will do a free call on it before the payload has any chance to get executed. This might not sound like a problem but it looks like lv2′s heap implementation will overwrite the free’ed space with 0xABADCAFE and thus destroy the payload.

Here (pastie.org/4755699) is my sample implementation for 3.41 lv2_kernel (although the vulnerability should be present in all versions of lv2 up to the latest firmware), maybe someone of you will find a way to overcome problem (2.) and can get something nice out of it because right now it’s only good to crash lv2.

From Mathieulh (via pastebin.com/naxXkv3M):

The footer signature is still not checked upon npdrm self files execution as of 4.21.

Because kakaroto says something that doesn't make it true. Basically he found a check in 3.55 that was not even called and assumed they used it in 3.60+.

Of course they do whitelist npdrm now so even if the footer isn't checked you cannot run your own npdrm selfs signed with keyset lower than 0x0D making the whole debate rather pointless. Aditional checks are now performed on the actual file format as well such as the segment counter flag that needs to be set to 0x01 except for the very last segment.

Finally, from KDSBest (via twitlonger.com/show/jcmh80): Since naehrwert posted an lv2 exploit I will do so too . The stack pointer points to lv2 and if we do a syscall, the syscall saves register to the stack HAHA.

Btw. It just crashes the console for now, since I totally overwrite dump the lv2 or some memory addresses I don't know. Feel free to try around, adjust the address of the stackpointer and so on. If you managed to get the panic payload executed. Tell me!!! ^^

I didn't managed to make it work on 4.21 so I just did on 4.20

The last versions of scetool work fine also without zlib1.dll, I tested them myself.
