Bluetooth + Remote issues

My flex box was working just fine up until a week ago now. It won't connect to ANY Bluetooth devices suddenly. No devices show up on the list to try unpairing/repairing and the discover section only has a loading symbol that never moves no matter how long I wait. It's completely blank under the Bluetooth menu settings. I've tried a system refresh more than once, unplugging and replugging both hdmi and the power cord, no other devices were on or connected to said devices, the Bluetooth devices have a full charge and are in pairing mode.. none of the supposed fixes have worked, so I'm unsure what to do. 

While not the biggest deal because everything else works on it, i'm up late at night so I usually connect my headphones to not disturb anyone else in the house and use my sound bar during the day which neither will connect to or show up suddenly. 

Also, the remote is.. kind of broken. The down button and back buttons are pushed in, probably from being used a lot and being old so I have to push hard to get them to even register.. 

This all being said, is there a way I can get it replaced or, since the boxes are discontinued do I need the new xumo one?
