Hello ..

I have a Lenovo A390, initially was normal ..
Finally I try to upgrade to a custom rom .. but after I upgraded, and the data signal is lost ..
I tried a few ROM again, but still ..
Finally I try to restore to Stock ROM official from Lenovo, but the problem has not been resolved .. The menu Mobile Network Settings can not be accessed .. The menu is only greyed out .. can not be selected or tapped ..
I have 2 SIM on Phone but can not be accessed
But I still can see the contacts and SMS from the SIM card..
What should I do:???

I also do not have a backup of previous ROM ..

please help ..

Thank you ..
