First we start with the imei analyser. The imei is a very delicate number so you can't just randomly generate numbers and tweak 'em you have to first analyse it. This is how we do that; Let me use the infinix hot note example again. First we get the identifying number of the phone we want to change to. "358429063" the first nine digits of an imei number are the legit numbers the rest can be tweaked but do not change the first nine digits. After getting the first nine, you randomly add any 5 numbers. So we have 14 digits now. "35842906312345" remaining one more number. This last number is called the "check digit" so it cannot be randomly added. If you do, you'll end up having a bogus imei number that doesn't work. Now open your Imei Analyser and input the 14 numbers we have gotten into the box provided. And click analyse. It will analyze it and give you the complete imei number including the check digit. Your imei should have changed *#06# to check. Note :- I strongly advice you copy your phones original imei before changing
