Maintenance Boot Mode Bixby button not working

[Android Central Question]

OK so I have a problem my S8 SM-G950U. My big speaker button is not working and I found out at the maintenance boot mode because I need to use the big speed button to make a choice to use her normal boot factory reset ECT so now I’m stuck with my phone on the Mainesville mode without able to make a choice is there anyway around the big TV button as being the inter-command on the screen

Unfortunately, nope. If the button is stuck or damaged, there's no way to change or select the boot options unless you have the phone repaired or plopped into a service station (certified repair shops should have one as some Best Buy stores do).
