Does motherboard from other country works?

Hi everyone,

I droped my phone once and naturaly it makes a very little rift.And when i forgot that rift, i wanted to wash my phone. You probably guess that now, it does not work anymore. I think there was a very little amount of water that gone inside. I just unmount it and i see where the water was. I think of order a new motherboard. Unlocked but it come from another country of mine. Can someone tell me if it will works ?

I just join a photo of the part thas recieved water.

I hope nothing else is broken.
