Samsung stuck in a adb update mode

A

AC Question

My Samsung s6 installed an update overnight. When I went to unlock it this morning it wasn't registering my password. It just wasn't bringing the keyboard up. An error appeared saying the Samsung keyboard had stopped working. So I researched how to do a factory reset but when I got to the bios options screen I saw an adb update option so I chose that. Big mistake. It wanted me to send the package I want to apply but I don't know how or what?
I'd appreciate any help you can give. I don't want to do a factory reset and lose everything but that's a better option than having a broken phone :(
