working IMEI number (you should know how/where to get that by now)
First, we install the phone drivers. I noticed i could not get the phone to auto install its driver so i simply downloaded pdanet (google it) for android and installed it. Pdanet has compatible drivers for android phones. and Secondly, enable USB DEBUGGING under "Developer options" on your Android.
iRoot, Formerly Vroot, is a free one click Android root tool designed by XINYI Network. It has both PC and Android version but for Infinix Zero, PC version is required.
1. Install iroot on PC and launch the application
2. Connect phone using USB to PC
3. Click on "Connect device"
4. Click "Root"
wait for few minutes while rooting takes place. phone will re-booth 2-3 times, just relax and BOOM! Rooting done!!!
IMEI changing procedure:
1. Install the mtk droid tools and wait till button below turns yellow.
2. click "root/backup/recovery" and back up your phone
3. Go back and click "ROOT", it will ask you to use superSu already installed on your phone, confirm and wait for it to finish.
4. Click on IMEI/NVRAM, both imei's will be shown, just replace the one you wish with the blackberry imei and reboot your phone. Congratulations, your INFINIX ZERO has been successfully rooted.
Less i forget, you will notice that the superSu installed is in Chinese. Simply uninstall it and replace with Chainfire SuperSu or any other from playstore. Check root status with Root checker.
Insert glo sim and configure as usual.
