Stuck on boot loop for iPhone 6+ :(

My iPhone is up to date. This morning, I went on Facebook and saw a post about changing your date to January 1, 1970 and it will make your boot logo rainbow. I was curious to try it, so I did. Set my date then rebooted. No rainbow, but I found out my iPhone was stuck in a boot loop. I tried everything from letting it charge and hard resets. Whenever I connect to iTunes it says update and restore, and I've already installed the newest update so I installed the update, and when the files were extracting the restore my phone it said there was an error. Any ideas? I've tried everything.
