Hi Everyone! My Samsung Galaxy S went dead after the battery died, and then I left it off for two days. I plugged it in, fully charged the battery and now it turns on, and just after it shows the glowing S as part of the start up, the screen goes black. The arrow and menu buttons at the bottom are lit up so I know it's on and working, but it won't load up for use. I've taken out the battery and put it back in. When I hold down the vol button, power botton, and middle button on the front lower screen, it goes to a screen that says "Downloading...Don't turn off target!" WHAT IS WRONG and how do I fix this?
