Z3x select g550t click read cert and wait until it say error damaged security
Dont reboot phone
And then go to settings u will see your besband
If you dont see your bassband if it is still unknown bassband repeat read cert operation even if it say security damaged untill unknown bassband fixed
And still dont reboot phone
Then go to repair tab and only click patch cert

And voilaaaaa your network fully operational
Hit thankyou button
