Well, rooting your phone should be easy... Kingroot application for Android will do the trick.. To get it just go on your browser and google 'Kingroot apk free download' find it and download... Make sure you go to settings, go to 'Security' and turn on "Unknown Sources" to allow installing apps from other sources apart from Google play store. Once installed tap the root button and make sure you have internet connection. It should reboot... Afterwards...go to Google Play Store now and download "Root Checker"...open it use it to see if you have rooted your phone successfully...it should show a green symbol if your phone is rooted... If it's not rooted,
meaning King root failed, it will tell you it couldn't root your device. Though I am using an Infinix hot note x551 upgraded to lollipop.. The new software security prevented kingroot from working on my phone so I found a solution to that by going into my settings.. Scrolling down to "About Phone" tapping 'Build number' 6 to 10 times I think, to see a pop up message "You are now a developer" went back to settings page... Opened "Developers options" looked for "OEM unlocking" ..switched it on... Went back to settings page... Opened security... Went to "Device administrators" u should see Kingroot listed along with Android device manager... Just turn everything you see there on.. Then go back and scroll down to look for "apps with usage access" turn everything on too.. Now go back to settings page... Find and open "Accessibility" turn on Kingroot. You should see it there... Now leave settings... Go to Kingroot application and try to root again... Should reboot and work this time around... Then open Root Checker and check if phone is now truly rooted...

This should be what your phone should look like while successfully rooting... And what your phone should look like after rooting is confirmed by kingroot

Nice one I should try it
