I've tried all those troubleshooting tips including factory data reset but sadly "No Service" status re-appears. And here I am, started over again.

You can also try to replace your sim cards with the new sim card from providers, generally it helps

which android version you are using? If you are using android 8, then please upgrade to Android 9. if on android 9 it gets same then, there may be sim card slot reader issue, for this then only asus service can provide you the solution.

Even I am facing the same problems as mentioned by jorel since the update (I have the same phone model as jorel) and am also finding an abnormally long charging time and excessive heating of the device while charging since the update . I have tried all the above solutions given by Christine too but have not found it fruitful. Please help
