Hi, after updating UMI Z to Android 7.1.1 mobile data 4g/3g/2g is not working in my phone.I tried dialing *#06* to check IMEI number but I am not getting any IMEI number instead am getting error from operator as "dialled number is not valid".
I am from India and mobile operator is AIRTEL INDIA.
Please help
Perform factory reset after update.
Also go to settings - about phone - status - sim status and check IMEI numbers. If you have 111111 or 22222 you need restore IMEI numbers with SN writer http://community.umidigi.com/thread-1375-1-1.html
