Replacing iPhone 6 home button ribbon cable (error 53)

Recently while replacing my iPhone 6 screen, I ripped the bottom connector of the home button ribbon cable at the bottom of the LCD heat shield. I proceeded to buy a replacement LCD shield with a built in ribbon cable, and installed it. It instantly went into an infinite loop of the apple boot logo and a flashing red screen. I immediately took it off and installed the original shield with the ripped connector and the phone went back to working fine minus the home button which obviously doesn't work. The phone is running iOS 10. I have a few questions:

1. Will updating the phone in this current state (with a disconnected/ripped home button cable) brick the phone with an error 53?

2. Will replacing the cable with a better quality ribbon cable or LCD shield make the phone work or will this result in an error 53?

3. If this does work, will updating the phone with the new cable/shield result in an error 53?
