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


Sponsored Links
183w 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)

Props to mastag22, lastExile, Killer_In - our testers with balls of steel.

Enjoy!

No, Sony just started using checks for people peek'ing/poke'ing and it's not working anymore. So yes you can peek/poke with this pup, but it will just freeze the ps3 when the ps3 realizes you're trying to mess with it.

if that were true there would be a backup manager for every firmware from 2.85 to 3.41 and there's not. the jailbreak payload does more work than people want to give it credit for.

I think 3.55 has a different syscall table than 3.41 and the previous BM's used the address value from the payloads to know where to redirect the games, so the devs need to update their BM's to work with the new address of 3.55.

It asks to connect a mini-usb adapter from the controller to usb port on the ps3 but for anyone asking how to install peek poke cfw from 3.55 or geohot's jb cfw just go into recovery mode with peek poke cfw and install from there. Then just install geohot's from the xmb. I can confirm that open manager will freeze everytime you try to run it and multiman works but will not launch any game you decide to rip to the hdd.

Whether you choose to launch directly from multiman or launch from the xmb with a blu ray game inside, nothing ripped to the hdd will launch (for now). Backup manager 1.1 wont even install so unless its updated to run on 3.55 don't even bother with it.
