I just purchased a used Iriver H320, and after finally getting rockbox installed and a few files transferred, I'm having problems. The battery doesn't stay charged for more than about half an hour, and after charging it for the last time, I was playing a file and it stopped, and it won't shut off. Nothing happens when I plug it into the USB port either. I want to have it looked at, but since I bought it used, and installed Rockbox and am running the European firmware I have no idea where to send it. Can anyone help?
