JasonUK has released a new version of his handy PRX decrypter, which is now compatible with firmwares 3.10 and 3.11. This is a mod of Psardumper and it can decrypt individual firmware modules from all known retail firmwares (1.00-3.11). It also works with all current game PRX's.
This is a note from him:
Quote:
Instructions:- Make a folder on your memory stick called "enc" and place your encrypted
PRXs there. Then run the app and press X to decrypt them.
- The encrypted files will be replaced with decrypted versions.
- The app can also extract reboot.bin from a 1.50 loadexec.prx or later.
- Just place a DECRYPTED 2.60 or later sysmem.prx in the "ms0:/enc" folder and name it as "sysmem_reboot.prx"
- Then place a DECRYPTED copy of loadexec.prx from the firmware you want reboot.bin for, and name it as "loadexec_reboot.prx".
- When these two files are detected, an option to obtain reboot.bin (by
pressing SQUARE) appears in the application.
Limitations:- It is impossible to decrypt *sigchecked* firmware files as they are entirely different from their unsigchecked counterparts. Just compare the two in a hex editor and you'll see what I mean. It might be possible to un-sigcheck these files if I bother to reverse the sigcheck process. But for now, it's not possible.
- Cannot decrypt game EBOOT.BIN files. You will get an "unknown tag C0CB167C" error. This is because they use a different encryption. I might add this for the next release.
- Cannot decrypt a few huge PRX files as they are encrypted with RLZ. I will fix this for the next release.
