I tried to root my Galaxy s2 Sprint. I turned my phone off and went to downloading mode, then I turned the odin and connected my phone to pc. After it, i hit start and nothing happened except saying "do not turn off the target." So I waited an hour and nothing happened or downloaded. SO i though theres so glitch in odin so i unplugged it and turned it off. Then tried to turn it on but it didn't. The screen is black on the blue light on. I tried to go back to downloading mode but it didn't respond. Now I can't turn it on or charge. When I stated to root my battery was full.
