Redmi Pro No Network

[knex666]

Dear Community,

I have a big problem with my Redmi Pro.
I have absolutly no connection to the network provicer.
First I try to explain how it came.
I have a micro Sim of provider a and another micro sim of provider b.
It was running great with the sim of provider a but I wanted to insert the sim of provider b.
After I done so I wondered why I have no connection. Setting back the sim of provider a in, and I wondered why I have no connection too.
both sim cards work in other phones (nexus 5) I have no idea.
I flashed the developer fastboot rom in hope to solve it but nothing happend.
there are workarounds for other mobiles by flashing NON-HLOS.bin but in the fastboot of the Redmi Pro there is no NON-HLOS.bin.
The Baseband is correct and he recognizes the sim card but says "No Service"
I hope you can help out

ADB:

Have you checked if the bands used by your provider are supported by this phone ? I had similar problem with 4G only provider but it's working fine with 3G in my country.

Hey sguerrini97,

thanks for your reply. The problem occured as I chaned the SIM Card. Before I was able to connect to 3G without a problem.
Putting in the old same SIM Card I am not able to get a connection anyway. Baseband shout be ok for 3G. (4G 800mhz is not supported) Is there another option to reset the settings as to flash rom etc? Maybe on MTK Mode or EFS Partition?

Thanks!

if you have root try to clean all the data on the root/nvdata/

Thank you very much for helping. Just before I´ll clear /nvdata what is the mission of this folder - will I lose my IMEI etc? It would be no problem to restore it but I would like to know what I´ll do ;-) and I didnt find any helpful information on the net.
So thank you! I´ll give you an update.
