How to change Qualcomm based android device IMEI

I believe some Qualcomm Device users are finding it difficult to change their Android device IMEI. If any of the old method did not work for your device, here is another perfect working method. The method has been tested to work on Xiaomi redmi 1s, MTNSmart S720 and Samsung Ace 4. It may not work on all Samsung devices, but you might be lucky.

Note: Changing of IMEI is illegal in some countries, and I will not be held responsible for any consequences that befall the changer.
Don't forget to write down your original IMEI number and keep it safe. Also, backup your original IMEI incase anything goes wrong, you can easily revert back.
