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


Sponsored Links
135w 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:

Download: [Register or Login to view links] (2.84 MB) / [Register or Login to view links] (2.84 MB - Mirror) / [Register or Login to view links] (2.84 MB - Mirror) / [Register or Login to view links] (172.19 MB)

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.

the thing here is that they didn't tell anything about the dongle itself, maybe they already pawned the dongle's security chip (ATMEL that is) and they didn't tell it publicly so once TB released something new (security or algo or something), DUPLEX, N0DRM or whatever can do the same to piss off the TB makers again and again.

As always, if TB makers decided to do it all over again with new hardware to support their new security system, a lot of existing TB users will be pissed off for sure.

It seems to me so. They'll pull out new TB CFW v3, new dongle payload, change DRM algo so all new games will still require TB.

They won't quit the scene so easily.

friends, i don't understand. is it the END for TB, or they going to upgrade the cracking (lets say, i don't know to play a 4.2V games) and come back again to the scene?

i'm very confused on what happened to them and why they are very quiet...

Well it looks like I was better off not getting the dongle after all.
