  IMPORTANT:What we are going to do next is that we are going to Edit this file to Put the desired IMEI Number in the File

  Our work is to replace those numbers with the IMEI of your own device.
• Now Run the "IMEI Converter.exe" and Convert the IMEI that you had written from the back of the device to Hex

  08 8A 76 15 02 82 19 52 55
  
  and Replace it with the IMEI generated from the IMEI Converter.exe for the IMEI for Sim1
  NOTE: MAKE SURE THE PROPER SEQUNCE AND SPACING IS MAINTAINED
  
  To replace the Numbers Just Click on the Number and Type the new Number
  
• Now Find the following sequence of hex numbers for SIM 2
  
  08 8A 76 15 02 82 19 52 51
  
  
  And replace it with the IMEI generated by the IMEI Converter for the IMEI for Sim2
• Now save the file and Exit UltraEdit
• Now again Run the Minimal ADB and Fastboot and execute the following commands in the sequence
  
  1. adb shell
