If you have root access. Try apps like XPOSED Imei Changer Just open app and select Set Orignal if it doesnt show your orignal imei just type the imei you have written and tap apply.
Try using SP Flash tools. It's for mtk devices like yours. You will need the correct drivers. Look this up on XDA, there is a fair amount of risk involved. You MAY BRICK THE PHONE. I have a Canvas Knight,and the same problem occurred with me too. I finally gave up and chose an unrooted phone.
