SanDisk 16GB USB drive red light keeps flashing. Please help

Hi If anyone could give me some suggestions on what I can do to repair this usb drive that will be awesome. I have pulled the casing apart and tried to resolder the terminals with the plug is thinking that is that problem. All it does is flash red not reconinsing anything on the computer.

Thank you

I think this one is already bricked. Even if you still have the warranty, it cannot be replaced since it was open. Sorry but this is what I think.
