True Blue (TB) and Cobra PS3 JB2 DRM Dongle Payloads WIP

131w 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 [Register or Login to view links] 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_insert_htab_entry
  • lv1_undocumented_function_114
  • lv1_undocumented_function_115
  • lv1_allocate_device_dma_region
  • lv1_map_device_dma_region
  • lv1_net_start_tx_dma
  • lv1_net_control
  • lv1_panic (shutdown ps3 when TB is unplugged)

This payload do some HVCALL:

  • lv1_insert_htab_entry (map lv1)
  • lv1_allocate_device_dma_region (?)
  • lv1_map_device_dma_region (?)
  • lv1_net_start_tx_dma (?)
  • lv1_net_control (?)
  • 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
  • Start ps3peektest

If Peek Result is equal to 10 and true blue light is green -> work.

Here are the dumped files from fifa 12:

[Register or Login to view links]

-dumpedboot.bin -> decrypt EBOOT.bin fifa 953 ko (original eboot 68 ko)
-dumpedboot1.bin -> decrypt fifazf.elf 25 mo (original self 35 mo)

It work fine, just let it to dump all memory (until hdd led is off)

we have to increase size of dump uint64_t sizeelf = 25*1024*1024 ; -> uint64_t sizeelf = 35*1024*1024 ;

Again, I have the 2 files. What do I do now? They aren't the eboot as they are both too small. Does this just dump memory or decrypt the eboot? I dont understand what its supposed to do and why its so good?

BTW Here are the dumped files from TC Ghost Recon Future Soldier.

woah, this is great! wondering if it would be possible to make this a fself so it runs on debug 4.20 then you could boot a game and get a .elf

So I used this and dumped 2 files from Ghost Recon FS. Now what?

They aren't near the size of the eboot.bin so what are they good for?
