Hi please share the below things so that I can help you better: 1. Your phone's current firmware version - Settings - About - Software Information 2. Kindly elaborate your issue, when you say that WiFi & Bluetooth isn't working what error or challenge are you facing 3. RMA no of your job sheet so that I can check the same with the service center.
