Uh, you need to redirect people to the corruption-free downgraders. The regular downgraders mess up some of the IdStorage keys on TA-082/86 PSPs. This can lead to problems with the USB, WLAN, brightness, and battery. The original 2.71 downgrader is the worst offender of them all, modifying 9 keys when only one needs to be changed (and hence having nearly every problem known).
2.71 corruption-free downgrader:

2.80 corruption-free downgrader:

3.03 corruption-free downgrader:

and for those unfortunate enough to have run the original downgraders, I made an app to help fix the keys.

Maybe one of the mods can see about getting these files posted here along with guides to use them so that we don't have to refer people to MaxConsole.
