PSP V2.0 to v1.5 Downgrade guide

[jackleone]

where is the overflow.tiff file?

[moomoomoomoo]

I've noticed a question that people keep asking that never gets answered, and now I have the same problem.

I updated to 2.00, but all I got when I go to the photo viewer is I see the overflow.tif as a Corrupted Data.

Ack! Do I have a misbehaved version of 2.00? Is my PSP just weird? (I downgraded to 1.50 from 2.6 "successfully" but all homebrews were giving me a white with colored bubbles PSP starting screen then freezing. I figured I'd upgrade to 2 then downgrade to 1.5, see if that fixed it.)

bleh. Any ideas?

Ok... I've ran into some trouble with the MPH downgrader...

I have placed all of the files into the correct locations "index.dat and h.bin into the root directory, overflow.tif into ms0:\PSP\PHOTO, 1.5 eboot in ms0:\PSP\GAME\UPDATE)...

what happens is, when I push X on the memory stick below the photo icon, the PSP just locks up, freezes, and shuts off. when I reboot, it's still at v2.0... Please help

Nothing to say? Nobody has ever encountered this problem before?

EDIT: NVM, already got help from QJ.net. Thanks for all your help

I have a V2.01 instead of V2.0. Does this procedure works for 2.01 too? Does anyone downgrade a v2.01 before?

for 2.01 u need to upgrade to 2.5 or 2.6 and use the 2.5/2.6 downgrader at www.psp-hacks.com u also need the eloader(super bock) and GTA:LCS(unpatched) for this to even work so before u upgrade make sure u have the unpatched GTA:LCS

I have double checked Everything the guide has advised, and i have correctly done everything(to my knowlage), but when i try to get the 1.5 ver update, the message "Update not required, you have version 2.00" pops up. any solutions? Post or email me at [email protected] Thanks!

u need to go into photo first to run the downgrader then u run the update when u make sure the downgrader has "tricked" ur psp into thinkin its at 1.0(which its supposed to do) and when u run the update it only goes to 99% then u get an error THIS IS NORMAL just wait like 15 secs after the error message pops up then hard restart ur psp(by holdin the power button for 10 secs) and then turn back on and ur at 1.5

The problem is when i go into pictures, it freezes the SECOND i hit "x" and i dont get to scroll down to the picture. There is the option "digital camera Photos" and it freezes on that insted of the correct spot. also i cannot restart the psp, it auto restarts and there is no jumbled lettering on the side when it does.

try putting another image in your psp that starts with a letter before O, such as A-N. It worked for me, and I got that tip from PSPUpdates, not here, where nobody is.
