Well I was trying to jailbreak my touch using winpwn and 1.1.4 firmware. it got to the point where it rebooted, but instead of rebooting the screen just went blank. I did not unplug it or anything. I waited for about 5 minutes and nothing happened. Now, itunes doesn't recognize it, neither does my computer, it will not turn on, it will not force restart, it won't do anything. I have tried all suggested methods i have found online but it will not respond to anything.... is there anything i can do ?
