Hi, I have plugged my Galaxy S2 into my pc for the first time to update the firmware and it recommend I should backup my phone first. While doing so, the USB cable somehow managed to unplug and which stopped the process in the middle. I tried plugging my phone back in again but it wouldn't recognize my phone. I have a Galaxy S2 and I'm using Win7. I've tried to reinstall everything but unfortunately it did not work. Can someone explain how can I resolve this issue?
