You can only return it to the service center in order to get a new motherboard.

Hi @idpromotor,
You should contact your local Asus Service Center.
I will also send you a Pm with some follow up questions, please check your inbox 😉

My phone too suddenly switched off and now neither WiFi nor hotspot is turning on... I did everything but nothing is happening...
Replacing the motherboard is not the solution by going to service center. Its the software issue.
What should I do. Pls help me
