One us a bigger text two read the multiple identical posts for a solution .
The basic answer is to restore your backed up EFS folder as that is the first step .
Second try factory reset or flash stock firmware .
Fails then its a service centre repair .

hi friends
i have a trouble while updating my xcover2 from jellybean to MIUI v5 BETA 3.1
everything is working accept network.it shows No service while inserting sim CARD.plz solve my problem.
Maybe you lost IMEI , call *#06# if your IMEI doesn't show up try to downgrade old version in order to try to restore IMEI or write IMEI with OCTOPUS , you can search how to use without card on the internet .
I'm using kenzo from two years.
Recently I flashed miui9 official beta ROM.after that next day I can't get even 2g speed (around 80-90kbps). I tried lot of roms,patches, even flashed the modem via adb method and flashed latest firmwares, and I also downgraded to the older miui versions ? but nothing worked. I used my sim card in my friend's mobile (yeah kenzo) and he got perfect speed.
So ,if there any possible solutions please let me know and kindly help me.

When I tried to repair the EFS partition, my imei gone!!..
But fortunately irepaired it.
In the Qcn repair method I successfully got 4g+ ,but the speed is not the good...and unstable.. however I can't get the real 4g speed.
Thanks for your reply.
My device is Redmi Note 3 MTK, it was stolen 4/5 month ago, then i locked it via mi account. About one week ago I found it.
So, I unlocked it and found it's imei, mac address everything is unavailable.
As far I think they tried to delete imei or they mistakenly delete it because of bad flash. And nvram is erased.
I reset the imei via SN writer tool, had original imei from device box.
now every info is restored. But still I can't connect to network though mobile is detecting the sim. I can connect to wifi, only no mobile network. Tried custom rom and official rom etc.
How to solve this, please help.
Thanks.
Maybe u did report it to your telco provider (stolen phone) and they've blacklisted the imei?

Flashing firmwares shouldn't change a IMEI you need to check and make sure what ever IMEI is on your device passes cert of check and or isn't blacklisted
If imei change to 00000 and can't connect to network, means u lost it. Hope u had backup EFS.
