First of all, make sure that you’re running the latest version if iTunes. Then, just put your device in DFU mode and connect it to your computer/iTunes. It will download the latest iOS and install it for you. Good luck.

Hopefully you have a made a backup that you can use to then restore it back. The passcode will not be restored from the backup.
