Terminology

Before diving into the installation process, it's important to familiarize yourself with some key terminology related to CalyxOS, flashing, and the installation process:

Factory Image

A factory image refers to a compressed zip file that contains the complete CalyxOS operating system. It includes all the necessary files and configurations required to install CalyxOS on an Android device.

Flashing

Flashing is the process of installing a new operating system on an Android device. In the context of CalyxOS, flashing involves writing the factory image to the device's flash memory, replacing the existing operating system.

Android Device

The Android device is the smartphone or tablet on which you are installing CalyxOS. It could be a Google Pixel 7a or any other compatible Android device on which CalyxOS can be installed.

Host Computer

The host computer is the computer you will be using to interact with the Android device during the installation process. It is responsible for sending commands and transferring files to the Android device.

Fastboot

Fastboot is a mode on Android devices that allows for low-level interaction, such as installing a custom operating system like CalyxOS. It enables communication between the host computer and the Android device.

Understanding these key terms will help you navigate the installation process smoothly, ensuring that you have a clear understanding of the various components and steps involved.

Prepare your Android device

Before installing CalyxOS, it's important to properly prepare your Android device for the installation process. This involves a few key steps to ensure a smooth and successful installation.

1. Remove the SIM card: Start by removing the SIM card from your Android device. This step is particularly important if your device is brand new, as it can aid in the subsequent OEM unlocking process.
2. Enable Developer Options: To enable Developer Options, go to Settings > About Phone and tap the Build number seven times. This will unlock the Developer Options menu on your device.
3. Enable USB debugging: In the Developer Options menu, navigate to Settings > System > Advanced > Developer Options. Here, you can enable USB debugging, which allows your Android device to communicate with your host computer during the installation process.
4. Enable OEM Unlocking: While still in the Developer Options menu, you can also enable OEM unlocking. This step is necessary for unlocking the bootloader of your device. Simply toggle the OEM unlocking option to enable it.

By following these preparation steps, you'll ensure that your Android device is ready for the CalyxOS installation process. Taking the time to properly prepare your device will help avoid any potential issues and ensure a successful installation.

Prepare your host computer

Your host computer plays a crucial role in preparing for the installation of CalyxOS on your Google Pixel 7a. To ensure a smooth installation process, you need to complete a few essential steps.

Installing USB drivers

If you're using a Windows computer, it's important to install specific USB drivers to ensure device-flasher works properly. To do this, you can download the Google USB Driver and save it to your host computer. This driver will enable your computer to communicate effectively with your Android device during the installation process.

Download device-flasher

Next, you'll need to download the device-flasher.exe program. This program is crucial for flashing the CalyxOS image onto your Google Pixel 7a. You can save the device-flasher.exe program to a directory along with the CalyxOS image to prepare for the installation.

Put your Android device in Fastboot mode

In order to proceed with the installation, you need to put your Android device in Fastboot mode. This mode allows your computer to send commands to the device for installing the custom operating system. To enter Fastboot mode, connect your Android device to your computer's USB port using a USB cable. Once connected, you can proceed with the installation process.

By preparing your host computer in advance, you can ensure a smooth and successful installation of CalyxOS on your Google Pixel 7a. Take the time to install the necessary USB drivers and download the device-flasher.exe program, and don't forget to put your Android device in Fastboot mode before proceeding.

Verify Digest for Device-Flasher and CalyxOS Image

Verifying the digest for the device-flasher executable and CalyxOS image is an essential step to ensure the integrity and authenticity of the files. By comparing the generated digest to the provided value, you can confirm that you have the correct files for a successful installation.

To verify the digest for the device-flasher, follow these steps:

1. Open a terminal on your host computer.
2. Navigate to the directory where the device-flasher is saved.
3. Run the CertUtil -hashfile command.
4. Compare the resulting digest to the provided value.

Repeat the same process for the CalyxOS image:

1. Open a terminal on your host computer.
2. Navigate to the directory where the CalyxOS image is saved.
3. Run the CertUtil -hashfile command.
