PSP downgrade v2.0 to 1.5
all files on www.pspupdates.com
Welcome to 1.50, PSP firmware 2.0 users! MPH has created a WORKING downgrader from PSP firmware 2.0 to firmware 1.50. This takes advantage of the toc2rta exploit and allows for the full downgrade of firmware 2.0 to firmware 1.50. I have tried this myself and have successfully downgraded from firmware 2.0 to firmware 1.50.
Although this has been tried and found working, this does not mean there is no risk involved so use at your own risk.
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
What you do next is go into the Photo Menu on the PSP and it will show some jumbled text, which is normal. Wait about 30 seconds and then restart your PSP.
From there you will now have a new file in your PSP’s root directory called ms0:/index.dat.bak. In the next step you will go to you Game Menu, Then Memory Stick, and then Launch “PSP Update ver 1.50.”
It will then ask you to downgrade and lead you along to installing. Here is where I got scared. It installed to 99% then errored. This is OK. Restart your PSP and reboot it. It will come up with another error which is OK as well. Restart it again and you will have PSP firmware version 1.50. Enjoy, and welcome to the world of legal homebrew, not piracy.

Was reading about this earlier tonight on the web.Good news for those people with 1.52 and 2.0 fw I guess...
I'm happy with my 1.50 firmware at the minute though!
Still hooked on Everybodies Golf and no plans to part ex it for something different as yet...

Only 2.0 but you could of course roll back and forwards depending on whether you wanted to browse the web or run illegal copies and of course the great homebrew offerings.

you can get a web browser for 1.5 from www.pspupdates.com
I upgraded when 2.0 first came out but the web browser I found to be just a toy that I didn't use.

If you downgrade to 1.5 is it safe to upgrade to 2 again? Is the downgrade to 1.5 a proper downgrade to the original 1.5 firmware or has it been played with and not the true 1.5 firmware?
Has there been any reports of it turning psp's into bricks? Has anyone found a way of recovering the PSP if the downgrade fails for some reason mid downgrade?
Want to try this but at the same time dont want to end up throwing £180 down the toilet.
