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.

sony’s psp says its a virus on purpose to scare people so they don’t try to upgrade. i checked the files one more time with multiple virus scans and they are clean. the downgrade worked perfectly for me. i had 1.52 and had upgraded to 2.0 then i downgraded back to 1.5 and no problems what so ever. i infact used the files from this site, but i read instructions on other sites just to make sure this site was right. dont be tricked by Sony’s propaganda donwgrade your psp.!!!

kvega2 says
Hi,
I’ve already done the downgrade from 2.0 to 1.5. The UMD Emulator has been working fine. One day I decided that I wanted to upgrade back to 2.0 to play Madden 2006, the upgrade is not working. when I click on the PSP update 2.0 it brings me to a screen and there is no text on the screen. I only see an ‘X’ on the bottom of the screen so then I hit the X button and it bring me to another screen that also has NO Text. I only see an ‘X’ and a ‘O’ on the bottom of the screen.
HELP!! I’m stuck with 1.5. I can’t seem to upgrade back to 2.0
Any suggestions
anonomous says

blacky says
i have a psp 2.01 firmware what can i do to run homebrew or anything else im new to all this and whats the best memory to have at the moment thanks
Trevor says
**Please Note - I have the Japan Version of the PSP which uses circle to proceed instead of cross**
OK - I had the same problem, ie blank screen on the updater when going form F1.5 - F2.0
When on each blank screen as they appear press down on the directional pad a few times (5-10) and then press right on the directional pad, on the 4th blank screen you should then get a scroll bar - press down on the directional pad until you get to the bottom. Then press *RIGHT* again then circle. You will then see the install bar - still with no text. Once it has completed their will be another blank screen, hit circle - your psp will restart with a blue screen telling you it needs to restart and apply default settings.
Once it restarts go to thru the setup and your done - BACK TO F2.0.
