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.

thank you for answering! now I have this problem lv1.self (info in attachments)

I can make new (os core) to fit "update_file" with your lv1 decrypted files have tried to to use the script but I could not get the script to work (said it will work)

Dump lv1 embedded elfs Script

I did this script quickly to exctract the embedded files within lv1. This script doesn't use the file table, is ugly, but works... anyone feel free to improve it --PsiCoLeO 16:11, 22 May 2011 (CDT)

How to use it

Save the script in a file named

dump_lv1_embedded_files.sh

give it execute permissions

chmod +x dump_lv1_embedded_files.sh

feed it with decrypted lv1.self
