To quote: Today is a special day. This marks an important release. You are now able to dump metldr from a simple pkg install, instead of using linux resources. That's right, thanks to CMX, this awesome bundle allows you to dump metldr without going through red ribbons and debians!
Flatz, for the original root key dumper source.
Joon and Mike, for the tests.
CMX (he made it all possible)
(The build script is ready to use, but i was too lazy to upload the modified pkg source in the first link )
Finally, from haxxxen to quote: Since it is easy to port it in a few minutes, i have made now a pkg from erk/met dumper for fws 4.21, 4.46, 4.65, 4.70, 4.75, 4.76, 4.78 (cex or dex)
Btw, you only need 5 symbols, so you can leave and remove the rest: toc, extend_kstack, copy_to_user, memset, memcpy. further it is only syscall table and those 2 gameos lpar thingies needed.
On another note, you should remove/comment new_poke install, since it can mess up with cobra mode. disabled, the dumpers work fine regardless of running cobra or not.
The lv1 patches can be done dynamically with search patterns and only htab and spe patch is needed, since the others are enabled by default (at least on rebug 4.21)
