I have a Slim running 4.01 m33-2. Whenever I turn off Crisis Core (completely off - not sleep) I hear the UMD drive grinding for no apparent reason (theres no UMD in it, I'm playing an iso backup from the mem card) and I have to hold the power button up for about 6-7 seconds before the grinding stops. I was running 3.90 m33 with the same issue and i upgraded to 4.01 m33 thinking it'd fix it, but it didn't. Anyone know a good solution for this?
It might be your psp, do you have the UMD Mode set to M33? As in, No UMD Mode? because my brother has a slim psp, and hasn't experienced that problem... so I don't know what to tell you other than check to see if you have No UMD enabled...
I've tried No-UMD m33 driver as well as Sony Np9660 No UMD
I also just found out that flOw is doing the same thing...
[edit]
if I try the Normal UMD required mode and turn off the PSP while playing Crisis Core then I can stop the drive from spinning but the power light remains on until I hold the power button for 6-7 seconds...
this sucks, I hope I didn't semi-brick this thing with the pandora battery I made..
i personally don't think there's any bricking involved in your problem, i've messed with psp flashing big time and so far there's not even ONE psp i've not been able to bring back to life with pandora battery (home made too) and well pandora only messes with your software while you might be having a hardware driver... anyway you can never be sure of things like that, just try flashing your psp once again, and check if your umd drive also grinds with other games, if it doesn't, then the problem would just be the game conflicting with something in your psp which wouldn't be a big problem at all..
by the way, your psp isn't off UNLESS you keep the power button up until the green light goes off, when you just push it up and release it, the psp goes into "stand-by" mode, meaning, your psp is still running and your game is still on but the psp's just not using much battery power...
