How can I reset my Misfit Vapor X when it won't even boot after an automatic update?

Okay, so I bought a Misfit Vapor X. It was brand new, and worked for about an hour when it updated itself. Now, it won't boot and goes into a boot loop when I try. It will buzz, then show the Misfit logo for about ten seconds, and repeat the process. I pressed the main button and the bottom button and got the watch to go into the recovery screen. From there, I can choose: - **START** - **Shipping Mode** - **Restart bootloader** - **Recovery mode** - **Power Off** **START** goes into the boot loop **Shipping Mode** gives me a screen of red letters that show this: SHIPPING MODE PPG Fail or Timeout! LED1 3216, LED2 3832 IR 9003 **Recovery Mode** goes back into the boot loop **Power Off** doesn't, and instead goes to the boot loop. I googled the above cryptic message without any useful result. I can't get ADB to see the watch (I'm not an expert, so I may not be doing that right...)
