I'm not sure if there's a hardware issue but my psp has been really acting up recently... Here's a quick list of issues: -Home button does not work, the screen brightness button functions as a home button (the 'do you want to quit the game' screen comes up when you press it) and also adjusts the screen brightness (weird I know -_-) -Web browser doesn't work at all when you enter it it just boots you back to the XMB... -Issues running demos and ISOs in 3.10 oe... metal gear solid wont boot for whatever reason, several demos off of pspfanboy also will not boot -files getting corrupted on the mem stick, lots and lots of corrupted saves which is annoying to say the least -wifi issues. Randomly disconnected during online play, downloads sometimes will freeze the psp or will fail randomly -various other issues. I've tried many many different firmware versions. 2.71 legit, 1.5, 2.71 se, 3.10 oe, 2.6 legit... all have similar random issues. Does anybody know how to do a complete flash format to rule out any possibility of a software issue?? I'd just like to isolate the issue. I'm thinking my PSP needs to be junked but if anybody has any opinions or suggestions it'd be appreciated. Thanks in Advance.
