After flashing my BV6800 pro, everything works fine, including data over mobile network. My problem begins when I try to make or receive phone calls, the phone immediately desconect from the mobile network, with the signal indicator on the status bar, going to zero immediately and returning soon after I stop the tentative call. I noticed that after flashing, the imei were missing, but I already fixed that following instructions I found here. Also, the phone model and SN becoming missing on the about the phone section on Android. How can I fix this? I flashed the phone with the latest US version rom from the link available in another topic. Anyone can help me, please?

Thank you for your quick reply.
In the meantime, I flashed the phone again with the EU ROM and it works for some time, then it loses voice and data connection and needs to be restarted.
What isthe most suitable ROM to use in Brazil, EU or US? Is the FCT the same for both?

The phone now, can make and receive calls, however it keeps losing connection/signal. It usually happen after a long time connected to WiFi. I'm still awaiting for instructions on how to adjust the FCT back to 10, as it was lost during Flashing. Anyone knows how to do it?

I just do not have that .ini file for the BV6800 to import and download to the phone. Can you please provide a copy? Thank you!
