My Diamond just got all screwed up

Out of commission for an hour or so.
S2U2 was only showing on the left hand of the screen and only bits of it. I could not get the Diamond to do anything. Soft resetting didn't help at all.
Diamond was locked and could not unlock it.
I finally plugged the charger in and the Diamond was back to normal.
I then deleted v1.62 but I don't know if that is the cause of these issues.
Btw, I was still having locking issues after soft resets even with v1.62

I don't know what is going on and what is causing all of these issues.
Btw, I had 19mb of storage memory (not internal storage) left and then I cleared cookies with ClearTemp and now I have 30mb!
