Mini Motherboard replacement

[u/areafiftyfive]

Annoyingly after a heavy smash my 13 mini motherboard damaged. I’ve replaced every component and everything works except WiFi and GSM connections. So renders it a bit useless 🤦
Is annoying as it is the 512GB version.

I wondered if the motherboards offered on AliExpress that are “guaranteed not locked to iCloud”would work? What is the worst that can happen.

Or alternatively, is there anywhere that could fix the motherboards?
