DON'T DO THIS ON A RAZER PHONE 1 OR IT WILL BE OMEGA BRICKED! ONLY DO THIS ON A RAZER PHONE 2!



-----------------------------------------------------------------
Things that work and don't work:
-----------------------------------------------------------------

This section will update periodically as issues arise or fixes arise for said issues.

Note: Things that work: Bluetooth, all sensors, audio, 120hz (you need to go into the settings > Phh treble settings > Misc features > Force FPS > [email protected])

Things that probably work: Sim, LTE, SMS, etc.

Things that don't work for some reason: Magisk (root is available through superuser (the reason you would want magisk is for modules)), Games that have more complex audio/music such as: all of The Room games and Battle Chasers: Night War.

Remember, you can always flash back to stock if something doesn't work properly.

It would be great if someone could test: Phone things (text and calling)

-----------------------------------------------------------------
Important notes
-----------------------------------------------------------------

THIS IS ASSUMING YOU HAVE ALREADY UNLOCKED THE BOOTLOADER OF YOUR DEVICE AND HAVE GOTTEN A SERIAL NUMBER OUTPUT FROM CMD AFTER TYPING IN "fastboot devices" AND MAKE SURE YOU HAVE TYPED IN "fastboot flashing unlock" AND "fastboot flashing unlock-critical".

***NOTE: I AM NOT RESPONSIBLE FOR ANY HARD BRICKED DEVICES OR ANGRY PARENTS. PLEASE DO NOT COME BACK AT ME SAYING I AM STUPID AND BRICKED YOUR PHONE. YOU DECIDED TO DO THIS. PLEASE PROCEED WITH CAUTION AND DON'T SKIM***

ANOTHER IMPORTANT NOTE: The stock firmware is actually really good for unbricking devices. Razer made it easy to fix your bricked device. So basically, if you can get in to fastboot mode, (which you basically always can do) you can unbrick your device super easily.

AGAIN JUST PLEASE, MAKE SURE TO FOLLOW ALL THESE INSTRUCTIONS CAREFULLY AND DONT SKIM OR ELSE YOU MIGHT BREAK SOMETHING!!!

-----------------------------------------------------------------
Introduction
-----------------------------------------------------------------

This is a quick and easy guide for how to install Android 11 on the Razer Phone 2. I'm kind of a noob here myself but I did this and it worked flawlessly. (also if you do run into any issues PLEASE don't count on me for troubleshooting tips (I'm not that great at that))

-----------------------------------------------------------------
Pre-requisites/Downloads
-----------------------------------------------------------------

Get the factory firmware for your phone. It's a good failsafe in case of a bootloop or a bad case of the phone not booting up. Download it here: P-SMR6-RC001-RZR-201022 (latest build at the time of writing)

Extract this with 7zip or WinRar (or windows. You will need 7zip or WinRar for the rest of this)

First you need the actual GSI. Get this version: AOSP 11.0 v300.l. Your gonna want to get any of the system-roar-arm64-ab ones. If you are kind of a noob like me, you will probably want the one with the google apps or gapps (this one: system-roar-arm64-ab-gapps.img.xz) this one will give you Gmail, the google play store, google play services, etc.

Use 7zip or WinRar to extract this.

Your also gonna need the Trinity Kernel (v2). This gives you TWRP and I'm pretty sure you also need this to have the ability to boot up the phone (I may be wrong but it's required.)

use 7zip or WinRar to extract this.

You will also need this zip file made by the legendary arter97 I don't really know what it does but you need it. here is the download: Download.

Don't extract this.

Put all these in a known folder that you can access later.

Alright. Now that we're done with the downloads, time to test to make sure your ready to put this on your phone.

-----------------------------------------------------------------
Making sure your computer is ready
-----------------------------------------------------------------

First things first. Go open your platform tools folder, shift-right click and open a PowerShell, or command prompt window there. Shut down your Razer phone 2 and turn it back on with the power and volume down buttons.
Plug it into your PC and type in
Code:
fastboot devices
you should end up with the serial number of the device. if you don't, follow Razer's instructions on how to install USB drivers and then come back here. Link to PDF.
If you get a serial number, close that and flash stock firmware by going into the aura-p-release-etc. folder, then opening flash_all.bat.

When it finishes and the screen goes black, hold the power and volume down buttons again to get back in to fastboot mode.
open back up the CMD/PowerShell platform tools window thing again.

-----------------------------------------------------------------
Installing/Flashing
-----------------------------------------------------------------

In your CMD or PowerShell window, (while in fastboot mode on the phone) type
Code:
fastboot flash system <file name>
in the <file name> area, just drag and drop the system-roar-arm64-etc.img file into your command line. your command will look a little something like this:
Code:
fastboot flash system C:\Users\user\Desktop\system-roar-arm64-ab-gapps.img
Wait until it says complete or something similar like done or something and has no errors.

Then, time to flash the kernel. it should just be called boot.img.
We will be typing in:
Code:
fastboot flash boot <file name>
Do the same thing that you did for the last command which is drag and drop the boot.img file for the file name.
Again, wait until it says done or complete and has no errors.

After that is done, use the volume buttons to select restart bootloader with your power button on your phone.

Go to recovery mode and swipe where it says to swipe. Go back to your computer and open file explorer.

Put the last zip file that I was talking about earlier (the f2fs thing) on the razer phone 2's internal storage. Head back to your phone, and press install.

Scroll down until you find the zip file and press it and install it. after that, go back to the TWRP home screen (with the 8 options) and click on wipe.

Click on format data and type in "yes" and click ok. click on "don't install" because you probably don't need the TWRP app on your phone.

The phone will shut down. Turn it on normally and everything should work!

Note: if you want your Razer logo to light up again, use Logo+. here is a download: Logo+ APK

-----------------------------------------------------------------
In case of failure
-----------------------------------------------------------------

If it starts bootlooping or is perpetually stuck at the razer logo, powered by android screen, go back into fastboot mode and run the flash_all.bat stock firmware thing. it will unbrick your phone automatically. Really make sure you don't skim if you try it again. If it did work (which it probably did), then have a good time with android 11!

There is one bug that has stopped me from going GSI. On every one I've tried, there is a game music bug that is common in many of the games I own. If the volume is set to below 50%, the music will cut in and out constantly. It resolves itself if you keep media volume above 50%. It may not be a deal breaker for everyone, but it was for me, as I use my RP2 heavily for games. Other than that, GSIs work beautifully. Thanks for the comprehensive guide!

Just curious, what games have that issue?

Ultimately at the end of the day I could not get Dolby Atmos and the RGB lighting on the back of the phone to work on GSI 10. Hopefully someone will come up with a work around for those 2 items in GSI 11.

I got the Razer logo working flawlessly with logo+. I didn't really see the appeal for Dolby Atmos as all it did was made it louder and made the audio clip more.

How can I get magisk on the phone though? it has Superuser pre-installed but it doesn't have support for modules and stuff (as far as I can tell). I really would like some info on how to install magisk if possible.
Actually, I may be misremembering. That may have been on a 10 GSI. I don't think I ever did get Magisk to work on an 11.
