PSPCipher: A PRX Decryptor can crack 0x2e5e10f0

    Source: http://bbs.a9vg.com/read.php?tid=1486475

    It's a completely rewritten prx decryptor based on 6.20 mesg_led_02g.prx.
    Right now there is only a POC version, but it already can decrypt 0x2e5e10f0, the key tag which pspdecrypt.prx failed to handle with. It also means you can decrypt PBOOT.PBP (game patch) since many patches use 0x2e5e10f0 to encrypt themselves.

    Usage:
    Use unpack-pbp to unpack a PBOOT.BIN.
    Rename DATA.PBP to EBOOT.BIN and move to ms0:/enc/.
    Run PSPCipher, the EBOOT.BIN will be decrypted.
    Replace original ISO with new EBOOT.BIN and PARAM.SFO. If you use Prometheus module then EBOOT.OLD instead.

    Right now, God Eater 1.01 patch and Idol Master SP patch are tested.

from mercyfull:

Install LPB Update v2.05 (EU version) on any CFW:
1) Extract DATA.PSP from PBOOT.PBP and rename it to EBOOT.BIN;
2) Copy EBOOT.BIN to "ms0:\ENC\";
3) Run PSPCipher and decrypt EBOOT.BIN;
4) Patch decrypted EBOOT.BIN with EDecrypt, press square (one version check);
5) Replace original EBOOT.BIN from LBP.ISO with decrypted and patched EBOOT.BIN from update file;
6) Create "UCES01264" in "ms0:\PSP\GAME\";
7) Copy dlc0003.arc dlc0005.arc and patch.arc from update to "UCES01264" folder;
8) Copy generated LBP.ISO (with decrypted and patched EBOOT.BIN) to memstick;
9) Run the game and enjoy update installation

0) DON'T DELETE corrupted data after succesful installation!
