Hello @EndLess,

Can you guide for the Redmi Note 4G - Dior? The QCOM Variant to be specific.
As dumb as I am I managed to corrupt the EFS/NVRAM or the IMEI Information without taking a backup.

Any help with this regards is appreciated a lot.

Thanks a lot.

I'm having the problem today with my 3g version.

Just flash the sMiui rom to solve all this problem.. Shortcut ways.. There's always a shortcut but we never dare to try.. I did and it's working..

Sharing is caring.. Cheers!
