If the computer detects that the phone is connected, you can try to repair the software using the Xperia Companion app

(If your device cannot be detected or started, or is a Smartwatch 3, then check the box with this information before you get started.)

if the SD/SIM card is defect in any way, that sure will affect the phone, try the 2 mins restart without them, press and hold on both the volume up and power keys, for 2 whole minutes.
