Hey all..

Hope you can help me with a problem I have when I´m trying to downgrade my PSP from version 2.0 to 1.5..

I´m doing following:

1. Download the MPH Downgrader. Also download the 1.50 Upgrade Eboot.
DONE!!!

Downgrader via: [URL]http://www.chez.com/mph/[/URL]
Eboot via: [URL]http://shockzone.free.fr/PSP/Tool/EBOOT_1.50.zip[/URL]

2. Extract the MPH Downgrader archive. Connect the PSP using a USB cable.

DONE!!!

3. Place the following files here:


- ms0:\PSP\PHOTO\overflow.tif
- ms0:\h.bin
- ms0:\index.dat
- ms0:\PSP\GAME\UPDATE\EBOOT.PBP

DONE!!!

4. Exit USB. Turn on the PSP (if it isn't) and go to PHOTO.

DONE!!!

5. Scroll down to overflow.tif. It should crash and show a screen full of random characters/numbers/whatev. THIS IS PERFECTLY SAFE AND NORMAL it is NOT BRICKED.

DONE!!!

6. Wait a few seconds. Reboot by turning off and on again (it may take longer than usual.)

DONE!!!

7. Inset the AC adapter and go to GAMES, then MEMORY STICK and run the "1.50 System Update"

NOT DONE!!!

When I´m trying to open eboot.bbp file my PSP says that the data is corrupted???

Why does it do that?? And what can I do to fix it??

Please help. Thanks.
