PSP Multiple Firmware Hack

PSP

Well, it’s always been a dream for PSP hackers to somehow have full control over the firmware. It’s been possible indirectly using Firmware Loaders like the ones made by MPH or SXT. But it’s still emulation. And the available resources for actually trying hacks are pretty less since most of the memory is used up by the PSP’s actual firmware.

Well, not any more. A guy called 0okm has been able to use an external 32MB Samsung NAND chip to boot firmware. Can’t figure out what I’m saying ? Well, for starters, how about being able to boot your PSP using an external source ? Yep, it might just be possible. But, it comes at a big risk. So it’s still one of those “Do not try this thing at home” situations for most of us.

0okm has been kind enough to provide a few pics and some technical info, including the schematics for the external NAND interface.

Here are his observations of the hack on different firmwares:

  • 1st PSP w/ FW 1.00
  • 2nd PSP w/ FW 1.00 update to 1.50
  • 3rd PSP w/ FW 2.50 Multi Firmware Mod 50% success – External FW 2.50, 2.60
  • 4th PSP w/ FW 1.51 Multi Firmware Mod 100% success – External FW 1.50, 2.50, 2.60
  • 5th PSP w/ FW 2.50 Multi Firmware Mod 50% success – External FW 2.50, 2.60
  • 6th PSP w/ FW 2.01 Multi Firmware Mod 100% success – External FW 1.50, 2.50, 2.60

If you’re overwhelmed by all this info, don’t worry. In simple words, what this means is that the future of PSP hacking is looking bright. There could be hardware hacks resulting from this in the future, but right now, it’s all speculative. And folks, do not even think of trying this at home.
