How to root Lenovo B A016a40 I am trying to root my Lenovo B A2016a40 but I absolutely cannot find a working method. I have tried several apps (desktop and android) such as KingoRoot, Framaroot and so on, but nothing has worked so far.

Here are some specs of my phone as a screenshot:

I have found this way:
(https://www.kingoapp.com/root-tutorials/how-to-root-android-6.0-marshmallow.htm) but I am not sure if this can be applied to my phone or not and I am scared to brick it.

Can anyone help? Thanks a lot!
I am recommending you to use kingo-root application because this app are very great for rooting devices and it won't put your device in brick if this app failed during root it automatically close itself and notified you.
Final is your decision and you are responsible for your work!!

Have a great day!!!!!!
