My player looks like this
Player
except mine has 1GB capacity
The first problem I experienced was the constant freezing while playing. It even freezes while I browse through the folders. After some time, it's now a blue screen. I can connect it to my computer and I can browse through it. I made no firmware changes to it. The only thing that happened to it was being dropped more than once. I hope someone could help me figure this out.
Edit: After leaving it plugged in, it recharged properly. The weird thing is that it's fine again. Now I'm confused.
