How to use Magisk Manager & boot.img to root Android

In this tutorial, we are going to show how one can root an android device by patching the stock boot.img using Magisk Manager. This comes in particularly handy for those on Lollipop and above where one-click-root apks like Kingroot don't work and would therefore require a custom recovery to root.

With this method, you won't be needing a one-click-root apk or custom recovery  (e.g Philz, CWM, TWRP etc) to root your device.

Requirements

• Stock boot.img for your phone model (its best its for your Build Number / Variant ) . You can extract from the stock rom / firmware of your device (you may check our collection at https://forum.hovatek.com/forum-89.html ) OR backup from your device using a hardware box e.g Miracle Box, CM2, Nck Box Pro etc
  
• Download Latest  Magisk Manager @ http://bit.ly/2ytLTLg
  
• Active internet connection on your Android device

Step 2: Flashing the patched boot.img

You have a variety of options to flash the patched boot.img depending on your chipset (e.g Mediatek MTK, Spreadtrum SPD, Qualcomm QLM etc ), the resources you have and your skills. Note that some flashing methods might require you to rename the file to boot.img

1. For those using MTK devices and have the specific scatter file for their device, you can flash the patched boot.img using SP flash tool or Miracle Box
   
2. For those using SPD devices and have the PAC file for their device, you can flash the patched boot.img using Research download tool by replacing the stock boot.img with your patched boot.img
