+Rep for being a scouser
Please…Correct me if im wrong.
flukes1 has patched Lv2 but is afraid to put it public, so he gives us the tools to do so ourselves.
Hoping that one of us has the smarts to figure it out and the balls to put it public and take the risk?
The following user thanked stocko for this useful post:

So today I’m releasing three tools which open the PS3’s hypervisor (lv1) and GameOS (lv2) to full read/write access from packaged userland applications. These tools can be used to create and test lv1/lv2 patches in RAM, which negates the risk of bricking your PS3 by flashing it with an incorrectly patched lv1 or lv2 binary. You can also use the tools to create a patched lv1 or lv2 binary, if you wish, although I suggest thoroughly testing your patches in-memory first.
Three tools are being made available today:
resign_self.py. This allows you to automatically replace any segment within a self and re-sign the self so the signatures and hashes are all valid again. Similar to makeself, but it is more suited towards patching lv1 and lv2 (and has been tested for this purpose).
insert_lv1_lv2.py. This is just a convenience script I made to take a modified, re-signed lv1.self and lv2_kernel.self, and automatically create a PUP which is identical to an original PUP except for those two files.
lv1dumper. This is an application which runs on the PS3 that you can compile and package using PSL1GHT and geohot’s tools. After running it, lv1 will be mapped at 0×8000000014000000 with read/write access, and you will be able to poke lv2 without the system shutting down. It disables the new lv2 memory hashing feature Sony added to 3.55 (probably to stop future USB jailbreaks).
