How to downgrade a psp from a 2.00 firmware to a 1.5 firmware


Download the downgrader Here


Download the Toc2rta exploit(dont use the h.bin that comes with this) Here

Download the 1.5 EBOOT Here


Now that you have everything you need to unzip everything. You will probably want to use Win Rar.

After you have unziped everything connect your psp to your computer using USB.
Go to My Computer and then Removable Disk. This is the psp.
Go to the psp folder and then go to the PHOTO folder inside that.
Put the picture from the Toc2rta exploit into the PSP/PHOTO folder.
Now exit USB mode and make that picture your psp's background.
Go back to USB mode and go to My Computer and then Removable Disk.



The first place you see is the root of the memory stick. Now go to the MPH Downgrader Folder you downloaded.
Stay in the root of your memory stick don't go into the psp folder yet. Put h.bin and index.bat in the root
of the memory stick.



OK, now go to your psp folder and then go into the PHOTO folder inside that.
Put the Overflow.tif from the MPH Downgrader folder in that folder.
Now go back to just the PSP folder and then go to the GAME folder and
make a folder in that called UPDATE. Put the 1.5 EBOOT that you downloaded in
that folder.


Now that you have everything setup, it is time to downgrade.
Get out of USB Mode and go to PHOTOS.
Keep going down until the screen turns black with letters and numbers on it.
Wait about 30 seconds and then hold the power button until it turns off.
turn the psp back on and go to system settings and it should say you have a
1.00 version system software.


Next go to th e GAME sction, then scroll down to Memory stick and click on it.
Find UPDATE 1.5 and click on it,it should then start giving you a 1.5 version.
At 99% it will show an error. Just hold the power button until the psp
turns off. All you have left is to turn on the psp and a screen will pop
up. Hold O and you are done. You will have a brand new 1.5 system.
If you want a free Video Ipod click .Here and follow the directions. If you want to trade
referals please PM me
