3.52 m33-4 settings resetting on their own
Hello all. I'm having a spot of trouble with my PSP. I was running 3.52 m33-2 for a while, and decided I would like to check out 3.71 m33. I went through the whole process of updating to 3.52 m33-4, then upgraded to 3.71 m33, but after a couple days, decided I wasn't so thrilled with it, so I used the downgrader that was made specifically for 3.71 m33, to go back to 1.50 (there was an official one floating around qj's front page a couple days ago). Afterwards, I went back up to 3.52 m33, then updated to 3.52 m33-4. Then the trouble started.
Now, for some reason, my settings (such as CPU speed) return to default every time I set my wallpaper on the XMB to a picture, and whenever I change the settings in the recovery menu back to the way I want them, the wallpaper disappears and is replaced by a black background screen on the XMB.
I'm wondering if maybe this is an issue with the internal flash, but I wanted to check with you guys, the experts, before doing anything I may regret later. Any help and advice on how to fix this issue would be welcome. Thank you.
