Am really glad to let all the samsung users in the house to know that finally, there is a way of changing the imeiof their stubborn samsung devices easily and for free without the need of odin, chimera tool, octopus box which costs a few box and only accessible mostly by mobile phone engineers. And the method iss easy, straight and you can get it done by yourself in minutes without the need of any techy around.

Pls Kindly note that imei changing is considered illegal in some countries. So i will not be held responsible for anything you do with this nor for any damage you do to your phone while carrying out the processes listed here. As this post is only for educational purpose.
