Finally, from zadow28: LV1 Dump for PS3 FW 4.21 released! Now this wasn't easy, but after some days I managed to dump the lv2. I have managed to dump the lv1 also, and that is more important. Made two links since this isn't something sony likes. Regards.
Here is the lv2_dump from 4.21 (linked above). Sycall table was found at offset 0x346390.

No its not for patching the kernel, but it would help getting there. This is an dump from the kernel and lv2 functions. So in an way its the lv2 kernel decrypted.remember the one we cant decrypt yet.
Together with the sycall table you would now see where the correct syscalls would be on ofw 4.21. Therefore exploiting it. Also here (above) is an lv2 dumper for cfw 4.21 i converted.. usb in the right slot. regards to the orgiginal creator. not sure who it is.
