iPhone 7 plus not recognized and no wifi

I got one iPhone 7 plus with unknown history that won't turn on. Phone was draining 0.0 amps so I open it , didn't see any signs of previous opening. Checked battery and charging port and with new charging port phone back to life but found other issues.

Phone can charge battery but pc can't recognize phone.

Tried different iPhone 7 plus on the same pc and all good , then tried this logic board in the housing of the good one and again “usb device not recognized”. Tried dfu and restore mode but with same outcome.

Phone can now boot but I'm stuck in activation screen , when I come to connect to wifi I can't see any network and only other way is connect phone to iTunes.

My last idea was automatic activation with different iPhone but that didn't work either , when I bring different iPhone close to this nothing happens.

Need some new ideas what to do next , usually I will try to replace tristar ic but this phone seems like have other issue.
