iPhone 7+ Reboot Loop

Hi everyone,

I left my phone plugged in before I went to sleep last night and woke up this morning to a reboot loop that just won't stop. So far, I tried to force restarting the phone and doing a restore and update using my MacBook. It downloaded the update and started restoring my phone. After it was completed, a pop-up appeared saying to keep the phone connected to my computer until it restarts. I waited and the Apple logo shows and the loading bar. After a minute, the loading bar loads a little bit and the phone shuts down again and back to the Apple logo and loading bar again. It just keeps repeating and repeating. Please help.

Thank you!
