PSP V2.0 to v1.5 Downgrade guide

[Cooe14]

there is supposed to be a 2.6-1.5 downgrader

No there isn't and if you do see one it's a fake.
And hrdb268 what FW do you have?

i need help. when i go to the game part, it says corrupted data. i dont know what to do. any help would be great. thanks

[Cooe14]

If you have everything set correctly your supposed to go to photo not game. But if you have already done that (your psp says 1.0 FW when you check it) then put the 1.5 Eboot in this folder-
PSP\GAME\UPDATE.

[hanr]

Yeah i'm starting over again and its at the black screen with the white letters. How long do i wait?

[Cooe14]

Till the memory stick light goes off i think then it will either turn it's self off or you will have to hard reset it (hold the power button up for about 15 sec or take the battery out.) then wait about 30 secs before turning your psp back on. Then go to system settings and see if it says you have a 1.00 psp (it's not really it's just tricked to think that so you can update to 1.50) then launch the update.

alright everyone thanks. just one more thing before i go, i know im annoying, where can i find the 1.5 update? tahnks for all the help. esp cooe14

[Cooe14]

Right here 1.5 Eboot Your Welcome
(the update will fail at 99% it's supposed to do that then it will reset itself and walla you have a 1.5 psp.)

[hanr]

im never going away. same problem. how do i update? please bare with me.

[Cooe14]

Does your psp say that it's a 1.0 psp? If it does put then make a folder inside your GAME folder called UPDATE and put the eboot in there then run it on the psp.

[hanr]

yeah i put it in the update folder. it says version 1.0. i go to game go to memory stick and then it says corrupted data.
