Can the motherboard on the Razer phone be fixed?

I think my Razer phone's motherboard had a short. The top speaker, camera flash, and GPS have stopped working as a result. Can this motherboard be fixed by some Microsoldering? I can't find any place capable of doing that.

Is it possible to replace the motherboard instead? I read that Razer does not provide provide shops with replacement parts.

I emailed Razer to find a solution and they said they can only sell me a new refurbished phone for the same price as a brand new Razer phone, and they're still asking me to send them my current phone too. I politely told them to go F themselves.
