Whew... Sorry for the lack of posts. I have been house sitting for a few days and besides that, I have been lazy.
Anyways to the good news!! The group MPH has released a WORKING PSP downgrader. I have verified and tried this myself and yes, it DOES work. I feel sorry to the people who donated to WAB and PSP-DEV for a product that was never released (and may not have even existed, we may never know).
I have tested the install by loading up the NesterJ emulator and it loads up just fine. It has also been reported that you can update back to firmware 2.0 if you want to (I have not tested this myself). Which will come in handy since apps are starting to come out for the 2.0 exploit.
Score: +1 for hackers. Sony: -1
Steps to use the MPH downgrader:
- Create an UPDATE folder in the /PSP/GAME/ folder of your memory stick
- Copy EBOOT.PBP (update 1.50) in /PSP/GAME/UPDATE folder
- Unpack MPHDowngrader.zip
- Copy overflow.tif in your PSP/PHOTO/ folder of your memory stick
(make sure you have changed your background to frame_buffer.png as explained in the toc2rta exploit.)
- Copy h.bin in root of your memory stick
- Copy index.dat in root of your memory stick
- Plug the AC adaptor
- Goto the photos and find the added image. You will see garbage, wait 30 seconds and reset the psp.
- Goto game on memory card, load 1.5 update and let install.
- At 99% it gives an error, reboot. You get some screen, it reboots.
- Done!
