PS3 LV2 Kernel Peek / Poke Patched, Backup Managers and CFW!

Sponsored Links
205w ago - Update: This method ended up failing because the LV2 address range is protected by Sony on PS3 with Firmware v3.55, so Netkas and flukes1 are now working on a patch for LV1 instead.

Today Netkas and flukes1 have successfully managed to patch the PS3 lv2_kernel in v3.55 Firmware to allow peek and poke syscalls, meaning PlayStation 3 backup managers and Custom Firmware (CFW) will also be able to make use of them!

Download: PS3 3.55 LV2 Kernel Patched with Peek/Poke / [Register or Login to view links] / 3.55 Peek-n-Poke Patcher GUI and 3.55 Peek-n-Poke Patcher GUI v2 by [Register or Login to view links]

From the ReadMe file:Patch to add peek and poke syscalls to PS3 firmware v3.55 by flukes1 and netkas (irc.efnet.net #ps3test)

To create the patched PS3UPDAT.PUP:

1. Use bspatch to apply PS3UPDAT.PUP.bsdiff to Sony's official 3.55 PUP, which is available from their website.
2. Run this from command line: "bspatch PS3UPDAT.PUP PS3UPDAT-NEW.PUP PS3UPDAT.PUP.bsdiff"
2. Ensure that the md5sum of the resulting PS3UPDAT.PUP is: 337831fac6a9b05074f73710c4bb7c86

Simply install the patched PS3UPDAT.PUP onto your PS3, then install geohot's jailbreak.

Our PUP can be installed over any firmware version, including 3.55-geohot. If you install over 3.55-geohot, you must reinstall geohot's jailbreak afterwards.

For developers: peek is syscall 6, poke is syscall 7 (same as PL3 dev payload)

I don't care of getting bricked for now so i don't know if it is dangerous or impossible to downgrade.

this is what I meant by using Kakaroto's CFW.

I'm not expert, not saying that I could do it myself, but maybe someone could edit Geohots update to remove the crap he's put in it?

Easier said than done, obviously - but so much easier

i don't think it will work on this way.. we have to know the way of the psgroove payload.

remember the first release was without BDEMU support so the BM doesnt work. what make the payload in the first point its patch the HV so let injekt mem pach without the HV patch you cant injekt anythink into RAM. and ther is the point they have look for not make a peek and poke first is patch the HV to inject MEM patches then they can put a peek and poke.

and then the BM not will work because of not enable BDemu support.

there is more then peek and poke to make on the kernel but i don't know if the HV patch is in mem or not.

just wondering if someone tried installing this but instead of installing Egohot's CFW, install Kakaroto's CFW, I would but I'm still on 3.41 Rebug and want to stay until this is all worked out as there still is no downgrade from 3.55.
