So the phone was dropped and smashed, I replaced the screen, all seemed to be working fine but couldn’t be further from the truth! No phone signal, can’t turn WiFi on and Bluetooth just spinning unable to initialise…any help please??
Normally, a screen replacement shouldn’t have you interacting with the Cellular/WiFi/BT antennas. did you follow this guide? I would encourage you to go through this guide and double check your work. You may have accidentally nicked an antenna or dislodged a connector along the way. there are also several antenna specific guides here if you want to see what elements are involved.
