How to change imei of MTK phones

Change Android IMEI with Mobile Uncle Tool..(Tweaking).

Tweaks are any small modifications intended to improve a system.
Lets Start:
Download the Mobile Uncle App from play store Here

Install, Open it up and go to Engineering Mode
Select Engineer Mode [MTK]



Swipe to the right and select CDS Information
Select Radio Information.
Phone 1 represents sim 1 and Phone 2 sim 2. So Tap Phone 2, you will see a command line like this=>AT+
 
Now just add this line to it EGMR=1,10,"15 digit Imei No you generated" and hit SEND AT COMMAND. E.g If you are to change that of sim 1 the command should look exactly like this AT+EGMR=1,7"imei No generated"

While Sim 2 should be AT+EGMR=1,10"imei No generated"
And you are done. Reboot your phone and check the imei using *#06#
