Here's what happened. My phone (running Slimbean 4.3) was plugged into my computer and I was going to drag and drop some music into it when the computer froze and then disconnected the phone. Phone also went black and now can't power on. No boot screen, and can't even get into download or recovery mode. Tried to use a different battery, doesn't work. Connecting it to the computer it, the computer makes a quick 3 note sound as if you disconnected something from a USB port. I think this is good bye for my almost 2 and a half year old Hercules?
