Hello 11.00!

AYO-

The next step is to dump an unpatched version. I should be able to finish this by tomorrow. All knowledge I got from reversing 9.0 is really useful when writing a kernel payload.

[ultimaweapon]

There are two additional syscalls on 11.00.

[VocalFan]

Though a lot of 11.00 games easily get backported to 9.00, so the last 2 might not be too important

Seems like there are some memory integrity checking in the PS4 called something like veri. If I patch the kernel without https://github.com/TheOfficialFloW/PPPwn/blob/master/stage1/stage1.c#L115 the kernel will panic within minutes after patching. Let's hope this checking is done only on the read-only memory.

[ultimaweapon]

Seems like veri check the other things too. I still got a panic even if I restore all kernel patches.

[ultimaweapon]

Seems like it is not possible to have execute permission on kernel_map with vm_map_protect. Never thought getting an unpatched kernel is a complicated task like this.

[ultimaweapon]

Seems like I need to call vm_map_protect two times with set_max set to 1 for the first call and 0 on a second call.

[ultimaweapon]

Still crashed. No idea what wrong here. Maybe I should give up on unpatched kernel.

[ultimaweapon]

It crashes in vm_map_protect somehow.

[SuchAFuriousDeath]

Maybe you should. at least for a while.

[ultimaweapon]

At least I got one with the patches that does not effect with Obliteration development.
