Root Guide

** Root will void the warranty and disable OTA updates **

boot.img patch method

I don't recommend updating the firmware OTA before rooting. There is a chance you will update your phone to a firmware that hasn't been released yet on the ASUS website. New updates are released OTA first and then about a week or two later they are posted on the ASUS website. If by chance you updated the firmware OTA and the firmware isn't on the ASUS website, you'll have to wait for the firmware to be posted before you can root.

If already rooted and updating firmware skip to 5b

1. Make a folder called ROG Phone to store all files needed

2. Download the following to the ROG Phone folder

-- Unlock Tool, aka Unlock Device App

---- https://dlcdnets.asus.com/pub/ASUS/..._SIGNED_UnlockTool_9.1.0.7_180912_fulldpi.apk

-- Latest Firmware - Under Firmware click on See All Downloads | Look at version number, not dates

---- Match SKU/Region - Example: WW->WW, CN->CN, JP->JP

------ Settings > System > About phone > Software information

-------- https://www.asus.com/us/Phone/ROG-Phone/HelpDesk_BIOS/

-- Minimal ADB and Fastboot - Portable

---- https://devsjournal.com/download-minimal-adb-fastboot-tool.html

-- Payload Dumper

---- Attatched image_extrator.zip script

-- Python

---- https://www.python.org/downloads/

-- Magisk Manager

---- https://github.com/topjohnwu/Magisk/releases

3. Unlock bootloader

-- Connect the phone to the PC via the side port on your phone

-- Select USB File Transfer on the phone; If problems connecting, update drivers on the PC

-- Copy the Unlock Tool to your phone's Downloads folder

-- This voids the warranty and disables OTA updates

-- This will force a factory reset, so backup your data

-- Use File Manager (in ASUS folder) on your phone to run the Unlock Tool from the Downloads folder

-- If asked for Pin select "Use your Google account" in white text (can't see) below the Pin request

---- Pin request YouTube: https://www.youtube.com/watch?v=aPKAEGptfas

4. Enable Developer on the phone

-- Settings > System > About phone > Software information

---- Tap "Build number" 7 times

5. Update phone to latest downloadable firmware

-- 5a

-- Open the ROG Phone folder and enable view file extensions

---- File > Change folder and search options > Click View tab > Uncheck Hide extensions for known file types > Click OK

-- Unzip Minimal ADB and Fastboot - Portable file

-- 5b

-- Copy the firmware to the Minimal ADB and Fastboot folder and rename firmware.zip

-- Turn on USB debugging

---- Settings > System > Developer options

------ Enable "USB debugging"

-- Connect the phone to the PC via the side port on your phone

-- Select USB debugging on your phone.

-- From the Minimal ADB and Fastboot folder run cmd-here.exe

-- From the command prompt (black window) type the following:

adb devices

-- To check the connection

adb reboot recovery

-- Select ADB on phone

adb sideload firmware.zip

-- Check that your phone was updated to the latest firmware

---- Settings > System > About phone > Software information

If by chance

adb sideload

doesn't work, try copying the firmware to the root directory (folder) on the phone and then reboot to install. Don't change the name of the firmware while using this method and you can't skip updates. So if there are two updates out from your current version, you'll have to install both.

6. Extract the boot.img file from the firmware using Payload Dumper

-- Use the attached image extractor script

---- Requires Python; Look at readme.txt

7. Patch boot.img using Magisk Manager

** Make sure that boot.img is from the same firmware version that is on the phone **

-- Turn off USB debugging

---- Settings > System > Developer options

------ Disable "USB debugging"

-- Connect the phone to the PC via the side port on your phone

-- Select USB File Transfer on the phone

-- Copy Magisk Manager and boot.img to your phone's Downloads folder

-- Use File Manager (in ASUS folder) on your phone to run Magisk Manager from the Downloads folder

---- Magisk Manager requires access to the Internet via wifi or mobile network

-- More Information

---- https://www.google.com/search?q=How...Methods)&ie=utf-8&oe=utf-8&client=firefox-b-1

------ Look at Method 2

-- Copy patched_boot.img from the phone's Downloads folder to the Minimal ADB and Fastboot folder

8. Flash patched_boot.img

** Make sure that patched_boot.img is from the same firmware version that is on the phone **

-- Put phone into fastboot mode

---- While the phone is off, hold down volume up and power buttons

-- Connect the phone to the PC via the side port on your phone

-- From the Minimal ADB and Fastboot folder run cmd-here.exe

-- From the command prompt (black window) type the following:

fastboot devices

-- To check the connection

fastboot flash boot patched_boot.img

fastboot reboot

Some users couldn't get a connection to a PC via a PC's Type-C USB port and had to use a Type-C to Type-A USB cable.

If by chance something went wrong and your phone locks up on boot, this raw WW firmware install will get you back up and going (so far it has worked for everyone). This can also be used to relock the bootloader, but it will not restore OTA updates.
