PSP


The excitement keeps on coming this week, with the release of firmware 3.00, the emergence of flashing applications for firmware 2.80, and rumors that Dark_Alex is on the brink of releasing 2.71 SE-C and his Hen D loader.

For PSP developers at least, the excitement keeps on coming with this release from Jas0nuk from our forums that allows you to extract PSP system software v3.00 firmware files. This Psardumper modification allows you to extract (not decrypt) files from 3.00. Just place the 3.00 DATA.PSAR into the root of your memory stick, and use PBP Extractor to get it (Can read PSAR files up to 18mb, 3.00 PSAR is 16.7mb).

We will state again, this Psardumper modification does not decrypt the encrypted firmware 3.00 files (instead it skips them), and therefore will not allow you to emulate it using DevHook or something like it.

However, what it does allow developers to do is take a sneak peak into firmware 3.00 and learn more about how it works. Here's a few things that Jas0nuk has found out about firmware 3.00 by using this mod:
  • No more ./vsh/resource/1.bmp, 2.bmp, 3.bmp (etc.). Instead, there's now just a 1-12.bmp which is grey. The firmware probably applies a colour overlay onto this.
  • audiocodec_260.prx and mpegbase_260.prx
  • Audio/video codecs from 2.60..?
  • Just 1 certificate in "./data/cert" folder
This application proves that although firmware 3.00 is quite solid in security terms, it isn't uncrackable! Jas0nuk would like to say thanks to Dark_AleX for Psardumper mod, and zshadow for the buffer fix. Remember to report any findings you have using this to the psardumper 3.00 mod release thread!

Awesome.

Hopefully someone CAN decrypt the files and emulate them on 2.8 or lower.

No life

People have lives, gazil. Don't blame the update for being 2-12 hours late, who really cares. OMG you found out about 3.0 first, please go update now and enjoy it's goodness (lawl 2.71 ftw)

decrypted

hopfully someone can decrypt this so dark_alex can add the features (like the .prx's and stuff) to 2.71 SE...that would be sick

Eventually........

Someone will crack it, especially considering the depth of knowledge gained from manipulating all of the other high number firmwares. The fact is, it will be cracked sooner or later.

PRX encryption is completely new

I'm trying to see what kind of encryption the PRX now use and so far what i found is not good: the encryption does not ressemble at any known encryption method i seen so far. will take a long time to crack. I dont know if this can be made into a custom fw because the lack of memory on psp's flash. (flash0) P.S. Expect 2.71 SE-C this week

Custom Firmware for 3.00

Just a suggestion (not requesting it or anything), perhaps a special edition 3.00 could be made for Devhook since there is not enough since there is not enough space in flash0 but there is a sufficient amount of space on the ms. Not sure if it would work because SE firmwares use two kernals. Oh, and good luck decrypting 3.00!
