PSP random button pressing

so the PSP is pressing buttons randomly in games.when i get in a game it just scrolls up and down and enters and leaves menus and when i finally get to a gameplay scene it works normally.help.i have custom firmware 5.50 U3R-2 and i accidentally installed a “patch” for cfw 5.50 GEN-A can you please be of any help i need the PSP to work as i dont have money for a new one.i have tried formatting flash1 and reinstalling the firmware(i didn’t downgrade u i just re-ran the updater)and nothing worked help please
Answer #1
is the game “rockband: unplugged” ? because i had the same problem while choosing in some menus. so, when it started moving by itself i just held the anolog stick down for a few seconds and then it works nicely again.
Answer #2
actually the game is resistance retribution but i will try out that trick thanks i guess and people keep this post alive i need a solution
Answer #3
Go back to 5.00 M33
Answer #4
umm how?
Answer #5
um…what i would do is downgrade back to official firmware and then install 5.00M33 cfw
Answer #6
so i gotta get a pandora battery and a magic memory stick right?and what would cause such immature behavior from my PSP i didn’t drop it in like half a year so i’m wondering could it be because i installed a patch on the wrong firmware or what?
P.S. your method didn’t work
Answer #7
If messing with the firmware fails, take it apart and clean out the contacts etc.
You’d be surprised how easy it is to fully take apart and rebuild a PSP (Well, a PSP-1000)
Answer #8
mine is a PSP-2004 and i’ve watched some videos all you gotta do is take the seal off where the battery is and unscrew and its done
Answer #9
It’s easy, but nowhere near that easy.
Answer #10
well it’s not that easy but it’s a walk in the park
Answer #11
umm if your psp already has CFW then all you have to do is just get the update and install it. So for you just get the 5.00m33 update and go to games and run the installer.
Answer #12
5.00 m33 i can’t install because it says i already have a later version and i do(5.50 UR32)so what should i do ? should i just wait until a new update is released because i’ve got the newest
P.S. i did took the PSP apart i took of the faceplate and it all worked normally but when i enter Resistance or LocoRoco the button pressing continues but i don’t press anything
P.S.2. i tried running a UMD game and everything was ok also i tried running PSX game with pops and everything was fine so i guess its just the PSP games and some homebrew also was acting strangely
