PS4 4.55 Kernel Dumper help?

[stooged]

i have been trying to workout how to dump the kernel to try and find the system version offset to enable vr like we did with the offset provided by xvortex on 4.05.

so i have tried to port the 4.05 kernel dumper to 4.55 and i think i have it all working good.

here is the 4.55 port 455-KernelDumper.zip

here is the dumped data from it 455_dump.zip

i dont know if the dump 100% correct too.

i am still having trouble trying to workout the offset calculation.

this value 0x4370000 should be 4.55 which is located at 0x7E42CA in the 4.55 kernel dump

but i cannot workout how to get those to work in this format that @XVortex posted for 4.05

*(uint32_t *)(kernel_base + 0x?????) = 0x5050001;

the offset in 4.05 was 0x1344618 and when i look in the 4.05 kernel dump at that offset i cant find the value for 4.05(0x4050000) its just 00000000.

im a noob at this kind of stuff but i am trying to learn so if anyone has an idea of what i am doing wrong some insight would be awesome.

EDIT

I feel I should clarify that I know how to poke at the specified offset using

*(uint32_t *)(kernel_base + 0x1344618) = 0x5050001;

its working out the correct offset to poke at that I am having problems with because the offset I get from the dump is not the same as the location I need to poke at in the memory.

@stooged isn't vr enabled on 4.55 by default as per this post?

@PS4 Guru
Most payloads you have to change hardcoded values to locations in the memory etc to suit 4.55 from 4.05 because they move around when the firmware is updated/modified.

@mschumacher69
Vr firmware 2.50 works on 4.55 but 3.10+ needs 5.00+.
Thats why i am trying to get the enable vr from 4.05 working on 4.55 because my vr is 3.10

Ohhhh gotcha.

Looks like offset 0x7E42CA for 4.55 that contains 0x4370000 not FW version, cos if you take a look in to dump 4.05 offset 0x7BA4AA the same value.

@stooged thanks m8 for the heads up.

 

[stooged]

never mind I worked it out, I realized my error was my head lol not remembering these values are stored backwards in hex.

I feel like a right stooge now LOL
