NOTICE this app is good as released tools for signing, decrypting ,etc.. If there is something what this external tool missing then its too bad and we need some new one it is tested with 3.41 fw and most of the games work, 3.55 is different story and it is good as tool from g... call package_finalize.exe.
i have confirmation that eboots from my apps workign just fine on 3.55 but not sure too.
Also once you ftp files over your PS3 make sure you folder is the exact the same as you selected from Mod tool. Game Folder name is not GameID!
