66w ago - Following up on the previous True Blue (TB) PS3 JailBreak 2 (JB2) DRM-infected dongle news comes a WIP update from Shadoxi on dumping and decrypting the TB and Cobra payloads below, as follows:
I have figured out where the payload is located of the TB and Cobra dongles. You can find it at offset @360000 in lv2_kernel and 7f0000 in PS3 memory. According to the PS3 Developer Wiki (ps3devwiki.com/index.php/ReDRM_/_Piracy_dongles) the LV2 dump payload at 0x7f0000 has also been decrypted @ LV2 dump 0x7f0000 (pastebin.com/3VG76HQs)
Drag and drop payload in IDA and load it in Binary file mode, Processor type PPC.Press "C" to convert in ASM code.
First of all you need to edit the header of lv2_kernel.self (from CFW TrueBlue) at offset 0x1D, replace 36 1A 00 by 4C FC F0. And decrypt it with unself tool from fail0verflow. Open lv2_kernel.elf with IDA Pro (in binary file mode), go to offset 360000 and press "C" to convert to asm code.
TrueBlue use some HVCALL:
lv1_panic (shutdown ps3 when TB is unplugged)
This payload do some HVCALL:
lv1_insert_htab_entry (map lv1)
lv1_panic (shutdown ps3 when TrueBlue dongle is unplugged)
lv1_undocumented_function_114 (map lv1)
lv1_undocumented_function_115 (unmap lv1)
We needed to dump lv2 and lv1 memory when the dongle is plugged in, so I created a modified TB CFW with peek and poke syscall. It works fine !
Finally, from the MFW_TrueBLue.zip ReadMe file: Warning this mfw can brick your dongle !!!
First install PS3PEEKTEST.pkg
Install MFW TrueBlue firmware in recovery mode
If Peek Result is equal to 10 and true blue light is green -> work.

say thank you you for everything they done in scene and be glad you get what you get, that makes me so mad, do i have any other siders in this, i know many if so give me a like this cheers, and stop pissing groups off especially the top of the top unreal, no brains whatsoever.
oh and this ans this and all 4.11 + games gee willackers, support me on this contributors or higher give us a like this to so that we are united in this view do not ask stupidly unreal, i am vecked.
Do you mean duplex and tb are the same people or e3 also? interesting. never thought about that but it makes sense. at least its free anyway now. thats the way it should always been.
i wonder if you can somehow mod deans eboot fix to include tb games. that would rock! also cfwprophet, i for one of many many members here at ps3news have great respect for you and your team and the work and knowledge you have. thanks and please don't let a few tools ruin it for us all.
i wish i could be in your underground scene bro.. LOL i'm not at all computer smart though so i'm of little use to the scene. but i love it all the same.
Why i say that: because i investigate in it a long time ago. If you don't trust duplex and me, that they don't use coredump is when you decrypt DUPLEX EBOOT the last section is present (in coredump there are no the last section).
I think they got others keys (3.60+) or someone in their team have reversed drm eboot.
