Rooting infinix note 4 x572 (oreo 8.1)

[Android Central Question]

Hello,
i bought this phone a week ago, it came with android nougat and it updated to oreo 8.1, i tried rooting it with android apps like kingroot with no luck, tried some one-click pc rooting apps with no luck either, made a quick search and found that a good way is use magisk manager, but i can't seem to be able to extract "boot.img" from my device using an app called "miracle box", it simply doesn't connect to the phone despite successfully installing the mtk vcom usb drivers for windows 10 x64..
please help, thanks

Install TWRP. Then install Magisk with TWRP. Finally, when you're back in Android, install Magisk Manager. See topjonwu's explanation of how to install it.

(Then I suggest that you install the Magisk Charge Switch module and set it to 80 40, to get the nest life from your battery.)
