The phone sees the SIM card in the second slot, although there is not even a second slot?

Question

Android

After installing the firmware, the phone thinks that I insert the SIM card into the second slot, but there is no second slot in my phone at all. I have no connection and cannot bind IMEI, because there is no SIM card selection window. What file can be responsible for sim cards?

Answer 1

Everything turned out to be simple, you just need to delete nwram (data / nwram) and after rebooting it will load a clean version.

Answer 2

Have you installed the firmware for your phone? I doubt.

Answer 3

The Chinese are such inventors ^_^
