Video Name: How to root Android using Magisk Manager & stock boot.img

Channel : Hovatek

------------------------------------------------------------

REQUIREMENTS :

(0) Unlocked Bootloader

To unlock bootloader in Lava X81 by Fastboot mode use the command

fastboot oem unlock	#unlock bootloader via fastboot mode

{{{{{ NOTE: Unlocking bootloader in Lava X81 will erase all the user data. So please take a backup before unlocking bootloader. }}}}}

(1) 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

(2) Download Latest Magisk Manager {Currently 7.3.0 (220)}

(3) Active internet connection on your Android device

(4) A windows 10 Laptop

---------------------------------------------------------

INSTRUCTIONS :

Step 1: Patching the stock boot.img

1. Install Magisk Manager 7.3.0 (220) APK on your android device.

2. Copy the stock boot.img of Lava X81 to your phone's internal storage or SD card whereever you want (Internal Storege\Dowloads is the better option)

3. Launch Magisk Manager app and check for latest updates. After the updates you will see that Magisk Manager is up to date.

4. Then, Select (Magisk is not installed. Latest 19.3 (19300)) Install > (Install Magisk) Install > Select and Patch a File >

5. Navigate to the location of the stock boot.img you copied earlier on (select Dowloads option or in my case, I used ES File Explorer File Manager), then Select it

6. Magisk Manager should begin downloading the magisk zip file for our arm64-v8a Device platform.

7. Once download is complete, MagiskManager will automatically patch the boot file and store it under

/storage/emulated/0/Download/magisk_patched.img

(Then I renamed it as "patched_boot.img" for our convenience)

Step 2: Flashing the patched boot.img

Among a variety of options to flash, I preferred Fastboot method

(0) Connect your Lava X81 one or two times to the PC (for preinstalling drivers)

(1) Boot your Lava X81 into fastboot mode.

(2) Open platform-tools_r28.0.1-windows.zip file

(3) Simultaneously press Keyboard's Shift key and Right click on the mouse, to open PowerShell window

(4) On the PowerShell use the following codes to flash:

Starting from phone's normal usb debugging mode,

adb devices	#Ensures your phone connectivity in ADB (Android Debug Interface) mode via USB Debugging

adb reboot-bootloader	#Reboot your phone to Fastboot Mode from ADB

fastboot devices	#Ensures your phone connectivity in Fastboot mode

fastboot getvar unlocked	#To check whether the bootloader is unlocked or not. It should be unlocked to proceed further steps

fastboot flash boot patched_boot.img	#Flash the Magisk Patched Boot image file in Fastboot Mode

fastboot reboot	#Reboot to the system from exiting Fastboot Mode​

(5) Congrats and check with a Root checker app for root status. While checking for root status itself pop out for root permission.
