How to boot into LG Aristo 2 TWRP Recovery:

b) Hold the volume key and power key at the same time.

c) When the LG logo appears, let go of the power key (while still holding the volume down key) and then click and hold the power key once again.

d)You will be prompted to LG Aristo 2's stock recovery mode asking you if you are sure you would like to delete ur phone.

e) Go to the option "yes" and enter.

f) It will then warn you that can remove all data from your phone.

g) Go to the option "yes" and enter.

You will be in TWRP after this.

TWRP Mode:

9) In TWRP go to "Wipe > Format Data" and then type "yes" and confirm it. (Do not hit reboot, click back a few time and hit reboot > recovery)

10) In TWRP go to "Install > Select Storage" and select your SD Card. Then look for where you placed the "magisk" zip file. Install it.

Your phone is now rooted.

On TWRP menu: Reboot.

Restore your phone if you created an LG backup of your important files (like lets say contacts or applications).

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

If any mistakes were made and you phone becomes locked, here is how to go into download mode to repair your LG Aristo 2 into its default stock rom. Credit to [MENTION=2651082]tecknight[/MENTION]: https://xdaforums.com/showpost.php?p=76837800&postcount=4

2) connect usb to Lg Aristo 2 phone (without connecting the usb into the PC or laptop)

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

What root means: In terms of PC language, Root means the superuser that has privileges to Add, Modify, and or Delete any kind of system files without prevention. Pretty much, it's like the actual Administrator account on a PC. Natively, whenever we buy a phone, it is as if to say, we are only using a guest account. Since the android OS is basically a Linux based computer (correct me if i am wrong) we can do anything we like... You want iOS emoji's on an android? A custom boot animation? Having root privileges allows you to go beyond your guest user restrictions because you then become the Admin.

Explaining the function of the provided Magisk app: It allows root privileges for programs intended for rooted phones.

There are other popular programs alternative of Magisk app, such as the SuperSU app: http://www.mediafire.com/file/2dljobq6yw93w76/UPDATE-SuperSU-v2.82-20170528234214.zip

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

After being officially done setting up your rooted phone, make sure you disable OEM Unlock to avoid seeing the caution message before every boot.

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

How to backup your phone.

Also, using ADB, backup your phone.

Windows:

Click and drag ADB file onto command prompt and paste " backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "

Linux:

Open terminal and type " adb backup -apk -shared -all -f "C:\Users\UserName\Desktop\backupfilename.ab" "

Update: For those who are encountering "Now unlock your phone and confirm operation" when typing the latter code, there is an alternative and much more easier and safer way to backup your phone.

Boot into TWRP and click on "backup" and then select what you would like to back up and then swipe to confirm the operation.
