1: Webusb Installer
1. Follow the instructions on the website, here: https://grapheneos.org/install/web
1. Make sure your phone is FACTORY UNLOCKED
1. Boot your phone, if a scary looking message appears, then it is bootloader unlocked already, if not, then do the following steps
1. Open the settings app (pull down from the top of the screen until you see a little gear icon , then tap it.
2. Scroll to the bottom, tap on About Phone
3. Scroll to the bottom of that menu, and tap on the Baseband number 7 times, this will unlock the Developer Options back in the main Settings menu
4. Navigate back to that menu, Tap on Developer Options
5. Scroll down to OEM Unlock, tap here to enable. If it is grayed-out, you are out of luck with that device, get a new one and start over.
6. If it is tap-able, tap it.
2. Proceed to installing whatever packages are needed for your operating system so that it can connect with your phone in the way that is necessary for the process to complete.
3. Reboot your device into Fastboot
1. reboot, and then hold the volume down key as it powers back on
2. Once there, scroll, using the volume buttons and the power button to make selections, down to Unlock Bootloader and press the power button twice to select and say Ok
3. While still in the bootloader, connect your phone to the computer
4. Download the Factory Images and signature files from the GrapheneOS site, and the signature checking utility to assure that it is Genuine.
5. Once it passes, continue to the next step on the list by clicking Flash Release, it should find your phone and begin the process for you.
6. After it finishes, you will need to reboot and go back into the bootloader, then lock it again by clicking Lock Bootloader on the website. Once that is done, reboot and start your newly GrapheneOS powered Pixel 3XL.
