Also, i think all should be signed with the lowest key revision (01) and 3.40 fw, that should work in 3.41 and 3.55 ps3 cfw version, no need to choose if will work in all versions i think. If all is made for 3.40 will work in both 3.41 and 3.55.
aldostools, how can i uninstall your tools, because it has added your tools as default program to bin/sprx etc files and maybe other things but i don't want them, and i didn't found the program on the uninstall menu of windows
There were some keys posted that had extra folders with other keys (and extras):
mkbs folder, passphrase folder, unlisted_appldr folder -- with lots of numbered subfolders 3-38(skipping some numbers)
each containing a set of ctype-integer, curve-integer, erk-integer, riv-integer (where integer corresponds to the folder number), and more folders labeled nonr and unkinteger. http://www.ps3devwiki.com/files/devtools/ps3keys/
