iphone 7 Stuck in DFU mode

My iPhone 7 just went off when I was using it and a black screen with a white wheel came on. after that it just went off. I tried using itunes to update and restore but when it gets to the restoring phase, it gives an error code 2009. i have tried using an original iphone cable and all but still. I tried hard resetting by pressing the power button and volume down button together but still. when i plug the phone in, I can feel it getting warm and my pc gives me a notification that I have inserted it but still nothing. can someone please help me?
