PSP-3000 hardware hacked with the old switcheroo

When you can’t beat ’em, change ’em. Some hackers from the Philippines did something ludicrous with their PSP-3000, switching its CPU with the PSP Slim’s. The result is that the PSP Brite/Slim hybrid is able to run homebrew that’s compatible with the Slim. Check out the full article for videos of the hack.

When you can’t beat ’em, change ’em. Some hackers from the Philippines did something ludicrous with their PSP-3000, switching its CPU with the PSP Slim’s. The result is that the PSP Brite/Slim hybrid is able to run homebrew that’s compatible with the Slim.

The drawback is that the old CPU doesn’t seem to be able to support the PSP-3000’s screen, so the hacker, Royginald, had to use a PC monitor. It kinda defeats the purpose of the PSP Brite since it’s selling point is the screen (despite all the “features” it comes along with), but at least he got it to work.

One explanation Royginald offered for the LDC screen not working was that the pinouts for the different models are different. Note that sound doesn’t work either. The system was updated to CFW 5.00 M33 before he started taking the hardware apart. Here are the vids to see how Royginald did it, in chronological order:

Royginald explains his reasons for doing the hack in his forum post (semi-translated):

1. To know if the PSP3000 can run ISOs
2. To learn more if $0ny did a GREAT alteration to prevent homebrew to run.
3. To identify more info in this new revision using HB apps (like PSP Ident)
4. To know if HB scene is Doomed for good (which is not ) on the PSP3000 (They can’t stop us all hehehe)

And some theories he proposed for the LCD not working:

1. Well as DA say theres an encryption from the new FW just for the new LCD.
2. Maybe if i can update this blindly new firmware installation will correct such lost files ..more like reinstalling Windows on a new CPU/Mobo PC style.
3. As of now even the Version3 CPU cannot be read by any Apps…that’s why there’s no way to back up its full nand image to read  .
4. Maybe a BSOD will fix this “glitch”
5. CPU from previous PSP running on a New Mobo simply says its really hackable! it’s only a matter of ipl / flashing .Who has the balls to run apps if you know that you cannot even Unbrick your PSP?!!
6. .With Pandorizable CPU i can run ALL Software Experiments on this UNPANDORIZABLE PSP. (try to brick Version3?? how’re you gonna bring it back to life?? hehehe)

Royginald says that the next step is to find ways to reflash the CPU on the PSP-3000’s motherboard:

It’ll install the files needed for the display “issue”, read the entire nand(for backup)…find ways to run DC7 at XMB,(PSP3k is pandora battery-proof)…Or if DA can read the entire nand of PSP3kCPU then write it on my PSP2kCPU ..patch some files for the M33.

Hopefully the Frankenstein experiment will help in fully hacking the PSP-3000.
