Hi @JoshCarlos, sorry to hear about your phone.

Based on the troubleshooting you have already done it does sound like it's related to hardware and not software, there is however a few things left to check.

Is it enough to just activate Wi-Fi and the phone turns off or do you have to connect to a Wi-Fi network before it turns off? Since it didn't happen when you were at the store, have you had the chance to try a few different Wi-Fi networks (preferably both 2.4 GHz and 5 GHz). For example, your network at home is 5 GHz and the one in the store where the phone didn't shut down is 2.4 GHz.

How long does it take for the phone to shut down after Wi-Fi has been activated or after you connect to a Wi-Fi network? If you restored any backup or installed the applications you previously had installed on your phone after the software repair, try rebooting your phone in safe mode and turn Wi-Fi on (connect to a Wi-Fi network). That way we can see if a third party application is the cause of the phone shutting down.

Let me know if that helps!
