BBQ10 motherboards

I have bbq10 snq100-1. That micro usb broke, tried to fix myself long story short I burnt that motherboard. I got an RFN81Uw motherboard but I don't know what model of bbq10 it's for. I though it was for snq100-1 but when I looked it up, it was for snq100-3 :( is this true.

The LED constantly flashes red with the battery and on charger or even without the battery and on charger...

I guess what I'm asking is there any way of resurrecting my bbq10 snq100-1 phone?
