Downgrade PSP v2.0 to v1.5 - September 27, 2005
After a long awaited time, the a PSP downgrader is finally available! This will allow all PSP owners who have upgraded their PSP to v2.0 to downgrade all the way back to v1.5. (this version will allow using homebrew applications) Also if you have v1.51 or v1.52, you will need to upgrade up to v2.0 and then you will be able to downgrade. If you do downgrade from v2.0 you will always be able to bring back v2.0 by doing the standard update procedure once again.
To downgrade do the following: (read entire post first! notes @ bottom)
- Create the X://PSP/GAME/UPDATE directory if it doesn’t exisit.
- Copy EBOOT.PBP (v1.50) into X://PSP/GAME/UPDATE folder.
- Unzip the PSPdowngrade.zip package and open the folder.
- Copy overflow.tif into X://PSP/PHOTO/ folder.
- Then copy h.bin into the root folder. (X://h.bin)
- Finally copy index.dat into root folder as well (X://index.dat)
- Make sure your AC adaptor is connected.
- In your PSP enter the Photos section, which will launch a little app.
- You will need to wait ~30 seconds and then restart your PSP.
- Then finally Game Menu and launch the v1.5 updater (downgrade).
- Follow instructions and then at 99% an error should popup.
- Thats normal so just restart the PSP and it should show an error.
- Now restart the unit one more time and the PSP should be ready.
Notes: Make sure there are no other Photos other than the overflow image present in the photos folder during this “downgrade” procedure. To restart hold the power button for about 10 seconds once it is off wait 10 seconds and turn it back on. All credit goes to MPH for creating this hack to downgrade PSPs. Please do not use this for illegal purposes (piracy), but use it to use legal homebrew apps and opensource type games. The PSPdowngrade.zip will inculde all of the files required to downgrade your PSP.

CDvd says
^^^ if you got to 2.5 i think it might be a little 2 far for right now, but if you just wait a few wks or so they will surely have an downgrader that will allow downgrading to 1.5.

If you don’t know how to program or if you have trouble adjusting your computer settings for proper performance, dont try to do this, you’ll just get stuck and pissed cause your psp wont work anymore. 8^D

Hello everyone, (admin here)
First of all lets help each other out instead of trying insult each other. For this to work you will need a USB cable and you will need a memory stick with enough storage place to place the files give to you above. Open the PSP Drive in my computer and open the “PSP” folder then open the “Game” folder now create an “Update” folder inside that. Once you do so place the EBOOT.PBP file into that newly created folder. After you do so go back to your PSP Drive and open the “PSP” folder then open the “PHOTO” folder. Then copy the overflow.tif which was also included in the .zip file into the PHOTO folder. For the last step copy the “index.dat” and “h.bin” into the root folder of your device. This means it will be sitting beside, not inside, the PSP folder that appears when you open that drive. When you are complete with the setup continue with the instructions provided above and you should be able to downgrade your unit.

P.S i have many games in iso which i have ripped from umd’s onto my computer so if ny1 wants e-mail me at h_abdoola786@yahoo.com. shup
STEVE says
i have version 2.01, it wont let me create or copy the update folder. can some1 help a broda out pls???
sahas says
sculpture, you are not suppost to edit the .tiff file. it is suppose to show it as corrupt. if you edit it then the hack will not work! and the .tiff hack to downgrade can only be used from 2.0 -> 1.5. Also it isn’t a very smart thing to advertize that you are distributing games illegally. :)
STEVE, If you have 2.01 you currently have no way to downgrade your unit! There should be some alternative son so be patient.
P.S. you may not need to downgrade at all soon !!! This is because the psp hack group has figured out a method to play homebrew on both 2.01 and 2.50! Keep checking http://www.skattertech.com for updates!
DAVE says
MY COMP SAYS THIS IS A VIRUS
Neon says
Crap!! Every time I try to copy overflow.tif to my PSP it says that the file has a virus called PSP.Brick. But alot of sites say its harmless. HELPY!
