You all will agree with me that an android phone without root access is not realy a complete android device..lols. I know some will say rooting is not necessary but trust me, it is very necessary to root your android phone because with root access, you can do whatever you want to do with your android device. Without wasting any time, lets quickly go ahead in rooting our Tecno Boom J7 and also change its IMEI to enjoy Glo 3gb Bis subscription.


  • Kingroot application. You can download from here
  • Working internet connection or wifi but it woun’t take more than 10mb.
  • A little patience.


  1. Go to phone Settings >> Security >> Unknown Sources and check it. It enables your phone to install apps not downloaded or downloadable from google playstore.
  2. Install the downloaded King Root Application to your device
  3. Lunch Kingroot application after installation. Tap the blue button at the bottom to start rooting. 
  4. Wait for the process to complete 100%.
NOTE: If your phone reboot before completing the process, its simply because of poor internet connection. So, restart your device and the rooting process again.
  5.  When the rooting process is complete, Kingroot Application will give you a success message.
  6.  Reboot your device and a new app called King User should be installed on your device.
To confirm if your Tecno Boom J has been rooted, go to playstore and download “Root checker” to verify.
