How to change/restore IMEI no. on 

Android phone and tablet.

Many of you guys may be facing th eproblem of invalid IMEI number. So here I provide you the trick to change IMEI number.

In case IMEI number gets cahnged or you get an error saying IMEI number invalid then don't panic.

Now before doing this trick note down your original IMEI number given on the box.

On the box of Dual Sim handset you will fing two IMEI numbers.

!) Open the Dialer and type *#*#3646633#*#* and dial this number. Doing this you will enter the Engineering mide.

2) Then swipe left to connectivity. 

In the connectivity click CDS information.

And tap radio information and then tap phone 1.

3) Now enter the command AT+EGMR=1,7,THE-FIRST-IMEI-NUMBER

And press SEND AT COMMAND.

For the second SIM tap phone 2 in the radio information and then type this command

AT+EGMR=1,10,THE-SECOND-IMEI-NUMBER

and press SEND AT COMMAND.

NOTE :- If *#*#3646633#*#* does not work and if you are using a MediaTek powered handset you can download the utility called MTK Engineering Mode for free from Google Play, it will do the same.
