PSP Multiple Firmware Hack |
Ó

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 slim 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.

I will love to have that mod on my PSP
it's the only way to keep homebrew alive ( cheap too ) so far , since most homebrew users are considering of getting another PSP for the new features and games .
uhm beside there are also retards who cant do anything by themselves ,but crying so f|_|cking loud
ha ha ha , not everybody are the same lol
PS: PSPHACKS are the ones who giving bs stuff that brick your PSP , not here ,you idiots ( they have some superFirmware flying around there , you should try it instead of bs-tting here)

And say you have FW 2.5, will you be able to boot up 1.5 or just the same or higher version?

Wait a minute, couldnt this mean a downgrader? Like if you can copy the flash to another chip, then couldnt you copy the 1.5 to a chip and put it on a PSP that is supposed to be 2.7 or w/e and then have it boot normally?
Reply
Multi-firmwares!! That means a 2.7 and a 1.5, on the same PSP hahah yes!!
////Wants a mod-chip....

It should be able to run what ever firmware you want unless there's traces of the firmware somwhere else than in the flash...
I still think my Idea was great, I mean, isn't there enough space under the battery to cut up a hole and put a socket in there? Custom-made of course. I've got to try this one!
Anyways, risking not to be able of play anything on the PSP is worth it if it works... And yes, I have a 2.5 that I'm starting to hate (the FW, not the PSP itself)

e.g. for psp 3, only 2.5 fw worked on the external nand chip.
here is what he says
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

FYI: The "32MB Samsung NAND flash chip" he used is just a memory stick!! (I may be wrong, but I'm probably not, since it's the exact same size and shape.)

yeah, just imagine fw1.5 with all it's perks and then a flick of a switch and it's ps1 emulator and fully functional web browser.

As for space restraints, I've come up with a pretty nice idea: The UMD drive. If you place the newest firmware on your actual PSP, and 1.5 on your 'external' NAND chip, you wouldn't need to use the UMD drive when playing homebrew.
Most ppl would ask "But wouldn't it have to stay in the UMD drive then?". Well, UMDs are round near the bottom, but your UMD drive slot is square (or rectangular), you could solder your wires to the MoBo, then the wires to a connector at, say, the bottom left corner of the UMD slot (so it wouldn't get in the way of an actual UMD). Place all the components in a rectangular box the size of the UMD, with the other end of the connector. When you want 1.5, pop in the 1.5 NAND flash "UMD" and off you go!
Lol, if anyone actually makes one using my method, give me a discount OK? lol, or better yet, you could send me one for free hahah XD

Does anyone have a link to a site selling these things?
I don't see why 0okm should have all the fun!
All i can say is let's get the soldering irons out and start burning holes in our psp's!

but the 32mb is out of production
I hope that a 64mb will fit in the psp

what you could do, is somebody could develop a Homebrew Loader UMD, made by Sony themselves Maybe!!!!!
Ever thought of that idea.....Let me explain.........
this UMD could Scan your Memory Stick Duo for any Homebrew on there, if it finds any, it would display those on Main Menu, for you to Select it, Press X to Run,( Just like the Eloader from Fanjita )
Simple as that.......
Its name could be SWAP MAGIC UMD.......
hows that sound..........

that would run Homebrew, just like they decided not
to allow on the last updates!!! ---actually I know nothing
about computers =)---
