Says its charging but its not!

Hi,
You just keep it plugged into the computer (in usb 2.0) until it says "Fully Charged", and then take it out and then see what happens.
Hope this Helped!

First make sure the hold switch is flipped off. If that doesn't work, see the troubleshooting guide here

instalation usb YP-K3

on the back you'll see a reset botton get a thin needle and press it.

Firmware upgrade:

Well personally i think you're done. You can always try bringing it back to the store and tell them it won't turn on. But don't tell them how you unplugged it because then they might say it's broke due to improper handleing and they won't giv you a new one.

how do you get pictures on the device?

well have had my k3 die on me once, pressed reset on the back and it worked again (this in the it doing nothing anymore case) as for the cgarging thing try it on another computer, when I charge my k3 at work it charges all day but I don';t get a full battery, at home I charge it for bout 2 to 4 hours to get full battery. I think it has something to do with ho many things u have connected to ur usb ports or how much output ur computer gives to ur usb, maybe it goes to like a lower voltage to preserve electricity, no idea how to change this but unplug unneccecary things.

Its due to your battery failure! Get it repaired at nearest service station

Maybe you have a USB 1.1 on your computer. YP K3 will charge much faster on USB 2
