Ooops! Sorry !
Dear oneplus please train your employees and evaluate your trainings....
I hope you are clear that we will not get VoLTE update as OnePlus x hardware is not compatible.
I got the second IMEI number from Google dashboard now the only thing is how to write second IMEI.
I will try your above method and let you know if...
They flashed Oxygen OS 2.1.X in my phone through remote support and one IMEI was recovered.
May be that flashing recovered EFS partition.
I am using oneplus x with Oxygen OS 3.1.3 and jio is working fine in my phone.
I have lost one IMEI Number in my oneplus x after bad flashing.
I don't have EFS backup with me and I don't know what the second IMEI...
No you don't need to change OS version. It will work in any OS. But make sure to select the network to LTE mode.
you have messed up with your modem files,
Try to find the lte band used in your country and select that if it works.
I am also facing this issue...
I have installed 3.1.2 and didn'tfind any bugs till now.
I am using 3.1.2 community build,
So is it okay to flash this ROM directly via recovery mode?
I have updated to 3.1.1 and sometimes while uploading when i select files app is being closed.
Does anyone else is facing this issue?
