65w 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.

No offense, cfwprophet, but did you actually have a working example or just a theory? I don't doubt your ability, but you have to realize the whole DEX+coredump idea is over the heads of most readers here (non-developers).
It should come as no surprise then that Duplex is seen as heroes for providing patches that remove TB DRM. If you wanted the credit, you needed to provide a working example that the average reader can use.
This is good news. I just got one cause it was free but now I can tear it apart and see what I can do with it. Also i will be able to run another firmware, so that kicks butt. Good news but on the hand what I they don't release any more eboots, so I closing I hope he found a way to make all eboots work. Thanks
