 Posted: Sat Jan 24, 2009 11:44 am Post subject: Which M33 boot module loads the Recovery menu |
 |
|
| iirc in the OE firmwares, recovery was loaded from the rtc.prx (systemctrl150). im pretty sure that this module applied the majority of the firmware patches before launching into the higher kernel. now that the ipl has been hacked and the firmware patches of m33 are applied from the custom ipl, does rtc.prx still load the m33 recovery, or is it loaded from the ipl. |

| Its loaded from recovery.prx. The ipl is just cpu instuctions, so it wont just load from the ipl. The OE source code show's that its load from recovery.prx . |

Yes sir, just CPU instructions. :)
vodkkaa, from the IPL. |

Nah! Those really are opcodes!! It's just a coincidence that they seem like they form words related to PSP modules. ;) :D |

You're a CPU instuction. |

so the recovery.prx is loaded and if RTrigger is not being held it continues on with the boot process. i want to knwo which module contains the instructions to launch recovery.prx when rtrigger is being held.
and how come the recovery.prx cannot be replaced with another prx. im guessing the recovery is launched using sctrlKernelLoadExec so if i put another prx in the place of recovery.prx, shouldnt it execute. i tested it with 5.02 GEN by taking the M33 recovery and copying to my flash0 in place of the GEN recovery and the M33 recovery successfully lauches when R is held, But if i take the GEN recovery and put it in place of the M33 recovery on an m33 install, the recovery doesnt boot. does DA sign his modules or something |

No, but GEN does "something" ;). Try to decrypt the recovery.prx from GEN with PRXDecrypter, you'll see.
Dump The IPL from your NAND. The rest will become clear. |

but M33 recovery works on GEN, but GEN recovery doesnt work on M33. I want to know what module gives the recovery menu instructions to boot. One of the modules must contain
| Code: | if (pad.Buttons & PSP_CTRL_RTRIGGER)
{
struct SceKernelLoadExecParam param;
memset(¶m, 0, sizeof(param));
param.size = sizeof(param);
param.key = "updater";
sceKernelLoadExec(RECOVERY, ¶m);
}
else
{
sceKernelExitVSHVSH(NULL);
} |
which one is it. im going out to dinner now, but when i get back ill take a closer look into the gen modules. |

| Listen to what the people are saying. There is a small check in the IPL for R Trigger and it launches recovery if found. |

recovery is loaded by ipl, there is no loadexec. custom Ipl detects key by using the sony syscon driver embedded in main.bin, and if R is found, it changes the load of the pspbt file by one contained in the custom ipl. This special pspbtcnf file has vsh module and some other unneeded module removed, and recovery and usb modules added. |

thanks. that is what i asked in the op. but how come i can switch the GEN recovery with the m33 recovery, but no the m33 recovery with the gen recovery. |

he probably encrypts it so that it doesn't work.
Of course once I have realized this, don't expect nothing from me (including vlf, popstation) to work on gen from now on:) Let this thread to be a prove of who started incompatibilities. |

@vodkkaa
recovery.prx can be replaced with with another user mode module. You will also have a big lump of free space (almost 45MiB) on the Slim for your module when booted in recovery mode.
From this you can further load kernel modules. Even VLF works in recovery mode. |

now it all makes sense to me. i thought you were checking the modules loaded but really it is gen who has encrypted their modules. thanks |
