From afiser on the PS3 Keys posted above: This is as simple as putting the bootldr keys (what you all call the lv0 keys released last week) in the scetool data/keys file and running scetool.exe -d lv0 lv0.elf

From zadow28: Found some interesting, when debugging lv1.elf from 4.31:

Only shows when debugging.. well thats where i'm at so far regards.

Dumps/Debug off core_os/Devflash files. 4.++

Have done some experimenting. Found out that you can actuelly run the self/sprx (ppc)

From core_os, and Devflash.. from "official" debugger,and dump them. You have to set up an fake Param.sfo, so the debugger thinks its an executable.. but the result is quite amazing. You really get an better overview, since you can see al the files it communicates with.

I use Ida pro 64 PPC proccesser to analyze, the dump. Then use Kakarotos scrips analyze_sprx.idc. Set new TOC, when the script tell you and reanalyze.

The dump is 4mb packed but 250 mb unpacked. I'll give an more deeper, TUT when i have the time. Works on all files so far i tested PPC ones, so all expect the spu files. Tested vsh.self/mcore.self/psp_emu.self plus many more.

Well here is the dump, for BDVD.SELF: [Register or Login to view links]

Off course you can debug all the files, and the embedded spu before dumping.

That's not how It works buddy, you need a flasher to downgrade back to 3.55 before installing 3.55+ CFW. I thought being on the scene for years would be enough for you to understand that.

why cant we downgrade with the keys we have again?? no one said anything about that
I've already answer that a few times, so did a lot of people. 3.55+ OFWs have better checks that stops you from installing CFWs. Can we bypass that? Probably not.

For example, 3.55 OFW have MD5 = A, 3.55 Rogero CFW have MD5 = B and 3.55 Kmeaw CFW have MD5 = C, all of them have different MD5, thus the installer can see the difference between the FWs. That was just an example though, people already managed to break MD5 security, so they are going with a better hash algorithm. In short, we don't have the right keys.

The reason for me to believe we won't bypass that security is because even some not so recent algorithms, like, SHA-2, that has been published in 2001, still haven't been hacked yet and there are probably more people trying to hack It than the PS3.

XBINX Cyro: Already seen some people confirming it works, but unless this gets new features people may want to stick to Rogero as he seems to be the most trusted dev working on CFWs right now.
