94w 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.

i have a true blue will do my best to get a dump for you to proceed where we were stuck for a long time but no it seems like we are going uphill again thanks shadoxi for starting this elf dumper , amazing work cheers triple thumbs up
Then we know the section headers start at 0x17EC228
Last section STRTAB:
ELF64 Section Headers:
Idx Name Type Flags Address Offset Size ES Align LK
029 0001 STRTAB --- 00000000 017EC0F7 0000012C 0000 00000001 000
So elf ends at 0x17EC0F7 + 0x12C. We add padding to 0x17EC228, and insert clean elf64 section headerd dump from original eboot.bin, right? Or does this dump ELF+section headers+some extra stuff we can cut off?
Anybody care to post a dumped elf (raw, with this tool) so i can look at it?
Following up on the previous update, today I am releasing my True Blue USB dongle PS3 ELF dumper which works with any PlayStation 3 Firmware greater than 3.56 to dump the encrypted TB EBOOT / ELF files once they are loaded.
Original 355 -> ok
True Blue CFW v2 -> ok
There are some bugs (size of dump ...) but it works. It's ELF dumper from memory and it work with True Blue cfw v2 and any 3.55 firmware because it doesn't use lv2 peek/poke.
Warning: It will not brick your ps3. But I am not responsible for any damage.
Enable dev_blind with multiman
copy libsysutil_np_trophy.sprx from /dev_blind/sys/external/external to dev_hdd0/ and rename it "orignal_libsysutil_np_trophy.sprx"
copy my modified "libsysutil_np_trophy.sprx" to /dev_blind/sys/external/
load a True blue game from multiman
run your game
wait few minutes (if you get black screen after 3 minutes reboot ps3)
go to ftp
in dev_hdd0/ there are your decrypted DUMPEDBOOT.bin
copy and rename it with another name.
Howto uninstall patch - Two ways:
You could uninstall this patch by replacing modified libsysutil_np_trophy.sprx by orginal libsysutil_np_trophy.sprx
Or update in recovery mode
Thanks to: Ps3dev
1 - Install TB ELF Dumper first as stated in its readme file.
2 - Start Multiman, it will make a dump of multiman eboots, so you must delete it first by browsing to dev_hdd0 then delete all DUMPEDEBOOT.BIN files you found there.
3 - Back to multiman game selection then select any TB game then launch it.
4 - Start the game from XMB then wait for some times until game start.
5 - Exit game now then start multiman again then browse to dev_hdd0 and now you must found a decrypted game dump.
From PlayStation 3 developer deank (via pastebin.com/avcM5iuU) comes a revision as follows:
write_message("Dumping ELF from RAM...\n");
uint64_t ptr= 0x00010000ULL; //ELF offset in RAM;
uint64_t sizeelf = 35*1024*1024; //Need a way to get size of ELF
