Dark_Alex has released yet another breakthrough in the quest of PSP firmware supremacy! He has just released his 2.7X PRXDecrypter application, which does exactly what it sounds like. It can decrypt PSP firmwares that previously couldn't be decrypted such as 2.7. Dark_Alex has only tested it on 2.71m, but the test came out successful, so you can bet on it working for firmwares 2.6 and 2.70.

Just like Dark_Alex's other programs 2 PSPs are needed, a 1.5 PSP and a PSP running firmware 2.6. Here's the instructions on how to use it:

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 memory stick
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, restart the PSP.

You'll now have the decrypted firmware in a new created folder: /FD

So, what does this mean for homebrew? Well, it could lead to an exploit being found in firmware 2.7 if there is one present. I am in no way saying that there is one or this will lead to homebrew on 2.7 so please do not jump to conclusions. It could also lead to 1.5 users being able to launch firmwares 2.6 and 2.7/2.71 on DevHook;

Man and I thought at this point in the PSP homebrew scene that it could not get much better but to me it seems as if the homebrew scene is only getting stronger every da with new prime releases of emulators and many great homebrew applications for the PSP. I can't wait to find out when we can emulate firmware 2.71 using firmware 1.0! Also great work on this NEO GEO emulator its coming along great and I am playing ever release with smiles hoping for more compatability. I wish you the best of luck on your work!

I think its getting stronger bi the minute also. And with ZX downgrading. MOOOAAAAAAAAAAAHHHHHHHHHAAAAAAHAHAHA
Imagine the possibilities.
&with NJ awesome updates and thrive for perfection.

Yes, My hopes for the 2.71 decryption is that it can be implemented into killer apps like DevHook to allow the PSP to emulate 2.71 similar to how it now emulates 2.50. That way, 1.50 users could have the best of both worlds without a MOD CHIP or Custom BIOS/Firmware.

But about NJ, my god! Is this guy a machine or what? This and Neo CDZ are premium quality emulators. Thanks to NJ!
