I installed Noble ROM in my SM J200G. After installing it, I was not unable to connect to LTE which I was before. My stock rom, when rooted, used to connect to LTE without any error. My carrier is Airtel (India). What should I do to connect to LTE? I have correct internet pack which allows 4g/3g.
In my phone settings, the data mode it LTE/WCDMA auto mode.
