Water damaged iPhone X 4013 error

Hi Guys,

I have an iphone x with severe water damage. I can turn the iphone on and put it in recovery mode. I tried to restore it with Itunes, but i get an 4013 error. I searched alot on google and found out that error 4013 could turn op while restoring by water damage in the FaceID / earpiece connector. I tried disconnecting al flex cables including the FaceID one, still wont restore in Itunes. I disconnected the cameras and all other cables but the Iphone still cant restore. Does anyone know what i can try next? I can solder by myself but solder the motherboard is to next-level for me. Any tips?

Thanks.
