2.00 -> 1.5 Downgrader Tutorial
BEFORE STARTING, DOWNLOAD THIS FILE: (It's a safe file) http://www.megaupload.com/?d=9QCKJB31 **If the file has expired, please PM me and let me know
Step 1. Plug a USB cable on the top of your PlayStation Portable, Click on the USB Connection icon on your PlayStation Portable and it will bring you to a new screen. Click on "Open folders to view files".
Step 2. Now, go into your X:/PSP/PHOTO folder and delete everything that is it there. Now there should be a .PNG picture format called frame_buffer that you've downloaded earlier in Step 1, take frame_buffer and drag it into your X:/PSP/PHOTO. NOTE: There should be nothing in the X:/PSP/PHOTO folder except for the frame_buffer.PNG
Step 3. Now use your PlayStation Portable and make the frame_buffer.PNG picture as your background. To do that, go to photo on your PlayStation Portable main menu screen, and click X and view the picture, now click triangle and set it as your wallpaper.
Step 4. Repeat Step 2.
Step 5. Go to your X:/PSP/PHOTO folder and delete the frame_buffer.PNG picture that's in there. (Now you should have nothing in your X:/PSP/PHOTO folder, but still keep your wallpaper for your PlayStation Portable as the frame_buffer.PNG)
Step 6. From the file that you downloaded, there should be 2 files in the "Goes In Root File" folder called h and index. Drag the 2 files h and index into your Memory Stick root file. (That's the place that is beside your main PSP folder. X:/drag the 2 files in here.)
Step 7. Also, in the file that you downloaded contains another file in the photo folder called overflow. Take the overflow file and drag it into your X:/PSP/PHOTO. NOTE: Nothing should be in your X:/PSP/PHOTO folder now except for the overflow file.
Step 8. Now, with your PlayStation Portable, go to your photo icon which is located on the main menu screen of your PlayStation Portable. Click X on the photo icon, and now you should be at a black screen with numbers (this is normal) . Count to about 30-40 seconds and if your PlayStation Portable did not turn off, then manually, you should turn it off by holding the power button up until your PlayStation Portable turns off. NOTE: If your PlayStation Portable turns off right when you clicked on the photo icon, then I'm afraid to say, but your PlayStation Portable is bricked. If it didn't you've managed it and past through the bricking part.
Step 9. Repeat Step 2.
Step 10. You are now left with only 1 folder in the file that you downloaded at the beginning. The file is PSP/GAME/UPDATE/EBOOT. Take the UPDATE folder and drag it into your X:/PSP/GAME folder. (Make sure you have the AC adapter charger plugged into your PlayStation Portable so that it's charging and is at lease sitting at a level 2 battery power.
Step 11. Launch the EBOOT file on your PlayStation Portable main menu screen by going to game/memory stick. After a successful launch, you will go through the same process as if you were upgrading.
Step 12. The last and final step! The percent will go, but will stop at 99% and will give you an error screen, this is normal.
Turn off your PlayStation Portable and turn it back on. When you have turned it on, a blue screen will appear, just click O and your all set!
