This a mod of the prxdecrypt sample of the pspsdk to be run on 2.60 and to decrypt 2.60/2.70/2.71
It's more or less the same i released about a week ago, but this time the decryption works
(it has only be tested in decrypting 2.71, but it would probably succeed in decrypting 2.70/2.60)
The program has 2 parts, one that must be executed in 1.50 and other that must be executed in 2.60.
1.50 part
- Copy __SCE__psar_dump2 and %__SCE__psar_dump2 to /PSP/GAME/ in the memory stick.
- Get the DATA.PSAR of the EBOOT.PBP of the update you want to decrypt (2.71 for example)
and put it in the root of your ms.
- Start the program.
This is simply a psardump (PSpPet) mod that will dump the firmware ENCRYPTED to /F0 and with the correct paths.
2.60 part
- Be sure you have the F0 folder with the ENCRYPTED dump obtained in the 1.50 part.
- Copy prxdecrypt27X to /PSP/GAME/ and start the program with the eLoader.
- The memory stick will flash for some time. When it finishes to flash, resstart the PSP.
You'll now have the decrypted firmware in a new created folder: /FD
TODO: decompress reboot.bin. It's decrypted but not decompressed.
the commpression of the reboot.bin has now changed. It doesn't seem to be gzip anymore
Signature/Avatar nuking: none (can be changed in your profile)
