Hi. Please let me know if you are online and I will try a walk you through some troubleshooting here http://livechat.satechhelp.co.za/ Otherwise:
- You will likely have a corrupt firmware
- And/or damage IMEI requiring a repair
- If you are still under warranty, then you may need to contact your retailer
- While there exist a DIY fix for a damaged IMEI, a full firmware reload may need you to depend on service centers.
