Alexandr272733Sadly, Nothing else will help you. Only solution is to replace the motherboard
Wi-Fi not working, just won't turn on
Tried all the options, flashed, rolled back the firmware, formatted, nothing helped
The nearest service center is in another country, 900 km from me. What should I do?
WiFi not working
Alexandr272733If the phone is under warranty, I suggest you to go for replace the motherboard. Incase the warranty is over, you may need to speak with Asus officials or send mails to them for a free replacement as what I did in my case.
is it worth changing the motherboard at all, maybe soon the same problems will arise with it
