- Make sure usb debugging is enabled in your developer options menu, your bootloader is unlocked and your critical partitions are unlocked. For instructions, visit https://developer.razer.com/razer-phone-dev-tools/general-instructions/?_ga=2.111753092.1097369801.1578321896-2010083175.1573219083?_ga=2.111753092.1097369801.1578321896-2010083175.1573219083

- Download and extract platform-tools to your desktop (for adb and fastboot functions) here http://https://developer.android.com/studio/releases/platform-tools

- Download the current release on Razers website here http://https://s3.amazonaws.com/cheryl-factory-images/cheryl-p-release-7083-user-full.zip or for a list of releases https://developer.razer.com/razer-phone-dev-tools/factory-images/. Unzip, and copy the boot.img to your phones internal storage.

-Download and install Magisk Manager on your device. https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

-open Magisk Manager, and select install, and when prompted, select "select and patch a file". Choose the boot.img you put in your internal storage.

-Once patching is finished (the patched image will be in the same location as the original image), move the patched boot.img from your phone to your platform-tools folder (will be labeled "magisk_patched.img").

-right-click within the platform-tools folder and select "open powershell window here" or "open cmd prompt here".
-IF USING CMD:
Code:
adb reboot bootloader
-IF USING POWERSHELL:
Code:
./adb reboot bootloader
. Your device should restart and boot into the bootloader.

-next, flash the patched boot image to BOTH slots,
-IF USING CMD:
Code:
fastboot flash boot_a magisk_patched.img
and then
Code:
fastboot flash boot_b magisk_patched.img
-IF USING POWERSHELL:
Code:
./fastboot flash boot_a magisk_patched.img
and then
Code:
./fastboot flash boot_b magisk_patched.img
-Finally, restart your device and verify Magisk is installed via the Magisk Manager app, and that WiFi is working.

NOTE Keep the original boot.img because it can be flashed the same way to revert to stock.

Thanks for this, I had been waiting on a method to root the latest update and this looks like it. Will try it when I get a chance.

I changed the properties of the android device in device manager as bdizthebiz user said.

Hi, thanks for your guide but before I attempt I am on the November 2019 Security Patch (Android 9), does this matter or do you not know? Sorry if it's a silly question.
