Team Rebug : LV2 Loader

[Newserator]

La team Rebug release LV2 Loader, une application s'adressant aux développeurs pour tester en live un Lv2_kernel.self modifié.

Cette application fonctionne sur custom 3.15, 3.41 et 3.55 Retail ou Debug avec patch peek and poke lv2 et lv1 mmap. Elle fonctionne en patchant des secteurs du lv2 puis en redémarrant celui-ci sans redémarrer le Lv1.

Utilisation :

- Copiez votre lv2_kernel.self modifié à la racine du dev_flash avec MultiMAN ou en FTP

- Installez lv2_loader.pkg

- Démarrez LV2 Loader depuis le Xmb

- La Ps3 devrait faire un bip puis redémarré, l'absence de bip signifie que cela n'a pas marché

F.A.Q:

Q: Can LV2 Loader boot DEX lv2_kernel.self?

A: YES. It will require your PS3 to be QA flagged. Don’t be fooled though. Just because you can boot the DEX lv2 kernel does not mean it will magically function like a DEX. For that to happen it will require more patching but this certainly makes the road easier to figuring it out.

Q: Can LV2 Loader boot lv2_kernel.self from a higher firmware?

A: In testing, booting a 3.56 lv2 kernel resigned for 3.55 worked without any problems. Keep in mind that amongst other things, the ps3 is still using the lower firmware’s appldr so there is no real advantage to doing this at the moment.

Q: Can this brick my PS3?

A: NO, NO, NO. The whole point of LV2 Loader is to prevent this from happening during your development of lv2 patches.

Q: Isn’t the offset for the lv2 boot path the same for all PS3?

A: NO. In testing on five different PS3 we came across seven dramaticly different offsets. Infact one of the PS3 at one stage or another in testing used four of the same offsets as the others and has now returned to the original offset from when we started.

Q: How do I reboot the PS3 without rebooting lv1 hypervisor?

A: Using glevend’s Reboot app will let you reboot the PS3 and maintain the modified lv2 boot path. As a bonus for REBUG users when changing modes with Rebug Selector the PS3 will reboot from the new path as well.

Q: As a user of REBUG firmware, if I boot the DEX lv2 kernel does that mean I am running DEX firmware on a retail PS3?

A: YES. REBUG uses the entire DEX firmware apart from 3 or 4 sprx (to allow QA flag support mainly) and uses the CEX lv2_kernel.self. Booting the DEX lv2_kernel.self will in effect, complete the set.

Credit and Thanks:

As always to graf and glevend for the hypervisor work. Big thanks to Dean for the handy memory mapping tip and adding support for LV2 Loader into multiMAN at the last minute.

Merci à the-green pour l'information.
