PSP exploits: 3k 5.50 - 6.xx+...

Post by Blade »

I've seen many posts on other forums -n- stuff about exploits on 6.20. there is a psardumper that decrypts the firmware, could this be of use on psp 3k? i managed to decrypt 6.20 using psp 1000 5.00 m33, but idk if it will do any good for 3k... there are also claims for 6.20 exploits that are said not to be released by some devs on other forums...

If you can find an exploit in the 6.20 firmware for psp 1k or 2k, it will work on the 3k and go. The firmware is the same (except for some hardware drivers).

Yes, there are some people who have already got exploits, and, as you might have seen in a recent video, a working homebews enabler. My guess is that they will not release it until they get another backdoor into the firmware - finding other user or kernel mode exploits, getting the aes256cbc keys for KIRK, etc - as they would not want Sony to lock them out in a subsequent firmware update... :)

since i have decrypted the 6.20 firmware and have its security certificate, do You think it would be possible to change the code within its files and maybe access the kernel when i run it on my psp? or even a spoofed "upgrade", like implying code from the GEN or M-33 updates?

Security Certificates? O_O

Last time I checked, there was that netfront browser which needed that mega CERT file. :D

:P

does anyone think the decrypted fw could be modded in any way, to execute unsigned code?
