I was running CM10 and decided I liked the stock ROM better so I went to flash back to the stock and when it started, my phone randomly powered down and wouldn't start back up. I can't get it to show any indication of life, charge, be recognized by my computer. The only thing I've been able to do so far is if I plug it into my computer with the battery pulled, it will show a red indication light but when I go to boot into download, the light will go out and it will make a disconnect noise. If anyone can help, please do.
