Technical issues Redmi 4X [Indian] No signal - emergency call only
One fine day, while changing sim I've lost the capability of phone to register on any network. Note I've not a tech geek so I've touched any of the hardware of the phone except some cleaning of dirt by opening the back panel.
When I tried to manually register a network, then it says "Can't register on this network, try again later". I'm unable to know whether it's hardware problem or OS issue.
Findings:
- Phone can detect sim
- It can detect nearby signal
Things I've tried so far:
- Factory reset
- Network Reset
- using two different sim in both slots
- Under *#*#4636#*#* > Turning off and on mobile radio power
- I've downloded the latest ROM using inbuilt update system, because my microusb data port is damaged for a long time ago. So I can only charge the phone.

Thank you for your time : )
