If you have a MediaTek chipset based smartphone, this software is going to be a boon for your damaged device. In the market, most of the smartphones are either using Qualcomm or MediaTek chipset.
Like I said, It may not work for all Qualcomm devices most especially Samsung that has dual sim click on modules, make sure IMEI changer is ticked then click on imei changer to launch the app =>Generate your blackberry imei and input it in the space provided and click apply =>Reboot your device and dial *#06# to check your new imei.
