Direttamente da ps3news una nuova notizia riguardo i payload trueblue e cobra.

Il coder Shadoxi ci da un aggiornamento per quanto diguarda il dump del payload dei dongle sopracitati.
vediamo le dichiarazioni:

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_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 !

mi piacciono soprattutto le ultime 2 righe :)
implementare le funzioni combra e trueblue in un cfw 3,55 che sia sarebbe molto utile..
ormai come da mesi sempre in attesa..

have a nice day ;)
