  • After making sure that your devices is found now we are going to unlock bootloader but you have to note that after unlocking bootloader all the userdata on phone will be erased so yo better take a backup of all your personal important data. If you are ready to proceed then type the following command “fastboot oem unlock” and after that you have to respond to your phone since it will ask you wether you want to unlock bootloader whereby you will loose your warrant and if you ready to proceed just press volume up button and wait for phone to restart and start erasing all your data and to complete boot up
  • Again boot your j8 to fastboot, after extracting the TWRP you will find inside the folder file named RECOVERY so copy it and paste inside the folder of your fastboot tool and again run command prompts and this time type the following commands “fastboot flash image recovery.img” and hit enter. Now wait few seconds for the flashing process to complete then type “fastboot reboot” and your phone shall reboot to normal
  • Now copy the SUPERSU you downloaded and paste it to your phone internal storage or sd card and insert it on your phone and power off the set
  • Boot your phone to recovery by pressing volume up and power button together and when you see logo on screen release power button and keep holding volume up button and you will be taken to recovery as how the image shows down

  • Click on install and scroll where you put SUPERSU and click it
  • Installation will take short time and after successful installation you will be prompted and now click on reboot then click system
  • Now you have successful gain root access to your tecno boom j8 and the next step is to fix invalid imei. If you were just looking for rooting solution then yuo ready to go
  • After gaining root now we are going to repair imei through ADB connection but not all tools have ADB method of imei repair and even those which support others failed, you will decide which tool to use
  • Connect your phone while powered on and make sure usb debug is on and mtp is selected as connection method
