When I try to connect the phone, I pressed Volume Down + Power Button just like you said, but it is not vibrating until I release the button. Then again it does not detect my phone. And the phone continue to show the spinning gear. What should I do? And here's my phone cycle when I connect it into a PC. Vibrate, Nokia sign, gear sign, blank screen, vibrate, Nokia sign, gear sign, blank screen, and so on. And here's a thing I should mention. If I try to hard reset it manually using the button combo, it does not show the exclamation mark. I pressed the volume down and connect my phone to a charger. But it shows no exclamation mark! Just showing Nokia, and then black blank screen, and then Nokia again, and black blank screen and so on.
