Overall, it can be done in just a few minutes. - -# Gathering Tools & Files - -## Android Tools - -First, in order to interact with the device, we will need the [Android platform -tools](https://developer.android.com/studio/releases/platform-tools.html). Find -the Linux download and save the ZIP folder to your preferred location. - -Once we've downloaded the files, we will need to unzip them, enter the -directory, and move the necessary executables to a central location, such as -`/usr/bin/`. For this installation, we only need the `fastboot` and `adb` -executables. - -```sh -cd ~/Downloads -``` - -```sh -unzip platform-tools_r33.0.3-linux.zip -cd platform-tools -sudo mv fastboot /usr/bin/ -sudo mv adb /usr/bin -``` - -## GrapheneOS Files - -Next, we need the [GrapheneOS files](https://grapheneos.org/releases) for our -device and model. For example, the Pixel 6 Pro is codenamed `raven` on the -release page. - -Once we have the links, let's download them to our working directory: - -```sh -curl -O https://releases.grapheneos.org/factory.pub -curl -0 https://releases.grapheneos.org/raven-factory-2022091400.zip -curl -0 https://releases.grapheneos.org/raven-factory-2022091400.zip.sig -``` - -1. Validate Integrity - - In order to validate the integrity of the downloaded files, we will need the - `signify` package and Graphene's `factory.pub` file. - - ```sh - sudo dnf install signify - ``` - - ```sh - curl -O https://releases.grapheneos.org/factory.pub - ``` - - Then we can validate the files and ensure that no data was corrupted or - modified before it was saved to our device. - - ```sh - signify -Cqp factory.pub -x raven-factory-2022091400.zip.sig && echo verified - ``` - -2. Unzip Files - - Once the files are verified, we can unzip the Graphene image and enter the - directory: - - ```sh - unzip raven-factory-2022091400.zip && cd raven-factory-2022091400 - ``` - -# Installation Process - -## Enable Developer Debugging & OEM Unlock - -Before we can actually flash anything to the phone, we will need to enable OEM -Unlocking, as well as either USB Debugging or Wireless Debugging, depending on -which method we will be using. - -To start, enable developer mode by going to `Settings` > `About` and tapping -`Build Number` seven (7) times. You may need to enter your PIN to enable this -mode. - -Once developer mode is enabled, go to `Settings` > `System` > `Devloper Options` -and enable OEM Unlocking, as well as USB or Wireless Debugging. In my case, I -chose USB Debugging and performed all actions via USB cable. - -Once these options are enabled, plug the phone into the computer and execute the -following command: - -```sh -adb devices -``` - -If an unauthorized error occurs, make sure the USB mode on the phone is changed -from charging to something like "File Transfer" or "PTP." You can find the USB -mode in the notification tray. - -## Reboot Device - -Once we have found the device via `adb`, we can either boot into the bootloader -interface by holding the volume down button while the phone reboots or by -executing the following command: - -```sh -adb reboot bootloader -``` - -## Unlock the Bootloader - -The phone will reboot and load the bootloader screen upon startup. At this -point, we are ready to start the actual flashing of GrapheneOS onto the device. - -**NOTE**: In my situation, I needed to use `sudo` with every `fastboot` command, -but not with `adb` commands. I am not sure if this is standard or a Fedora -quirk, but I'm documenting my commands verbatim in this post. - -First, we start by unlocking the bootloader so that we can load other ROMs: - -```sh -sudo fastboot flashing unlock -``` - -## Flashing Factory Images - -Once the phone is unlocked, we can flash it with the `flash-all.sh` script found -inside the `raven-factory-2022091400` folder we entered earlier: - -```sh -sudo ./flash-all.sh -``` - -This process should take a few minutes and will print informational messages as -things progress. Avoid doing anything on the phone while this process is -operating. - -## Lock the Bootloader - -If everything was successful, the phone should reboot a few times and finally -land back on the bootloader screen. At this point, we can re-lock the bootloader -to enable full verified boot and protect the device from unwanted flashing or -erasure of data. - -```sh -sudo fastboot flashing lock -``` - -Once done, the device will be wiped and ready for a fresh set-up! |
