Xiaomi Mi5 Basic


In case you got under Settings–>About phone Imei Null

Then probably the /nvram folder got corrupted (nvram is where imei baseband are stored )

Set manually your Imei back

Open your dialer and dial *#*#3646633#*#*

  • (That should open Enegineering Mode MTK )

Now go Connectivity–> CDS information–> Radio information

Phone 1
At “AT+” type in:

AT +EGMR=1,7,"your_IMEI"

Click on “SEND AT” button below

For the secondary SIM tap Phone 2 and type this command

AT +EGMR=1,10,”your_IMEI”

Click on “SEND AT COMMAND” button below a second time
Reboot phone

In case your Engineering Mode doesn’t show a CDS Information option get the engnering mode apk form an older rom or Flash an older rom, and follow the steps.

What actually happened to me was

I messed up **/nvdata** partition (nvdata contains IMIEI, Baseband, WiFi and Bluetooth mac addresses)

This is something that usually doesn’t happen.

With a corrupted /nvadat partition your smartphone may lose it’s IMEI , baseband both (Wifi, Bluethoot mac address), causing your smarphne to not recognize your sim.

There are many possible scenarios, mine was:

  • Imei: null
  • BaseBand: unknown

What i did was delete the /nvdata folder after a few seconds all started working again


not work


same thing :(


i don’t even have CDS Information


When your phone is in normal state with everything functioning install Root explorer and navigate to the below location >ROOT>DATA>NVRAM>MD>NVRAM>NVD_IMEI>MP0B_001
Select it and edit and delete any data there and paste new imei and save it . That’s it it works without reboot also

It worked for me


Are u kidding me??


didn’t work For me and it’s will not work because it’s doesn’t exist
