Custom ROMs For The Pixel 7A: How To Install Them

Here are the steps for installing numerous custom ROMs on your Pixel 7A. Devices from the Silicon Valley giant have long been known for being among the most active in custom ROM development. The Pixel 7A, the most affordable entry into the Pixel lineup, has once again lived up to this claim, and it does so with great style. Several custom ROMs have already been downloaded for this device within days of its launch.

What is the point of ditching the Pixel ecosystem for a custom ROM when the latter are themselves based on AOSP? There’s a reason for this: they come with numerous additional mods and tweaks [while you could try out most of these features on a stock ROM as well, but then you’d have to root the device]. Now that we have that out of the way, let’s get to the process of installing multiple custom ROMs on your Pixel 7A.

How to Install Various Custom ROMs on Pixel 7A

Each ROM you flash will wipe off all the data from your device, so make sure you take a complete backup before flashing. If you follow the steps below, AMS and its members will not be held liable in the event of a thermonuclear war, your alarm doesn’t wake you up, or any harm comes to your device and data.

1: Install Android SDK

In order to get started, you’ll need to download and install the Android SDK Platform Tools on your PC. The only recommended binary is the official ADB and Fastboot binary provided by Google. So download the file and extract it anywhere on your computer that is convenient for you. You will receive the platform tools folder as a result, which will be used throughout this tutorial.

2: Enable USB Debugging and OEM Unlocking

The next step will be to enable OEM Unlocking and USB Debugging on your device. As a result, your PC will be able to recognize the device in ADB mode if you use the former. In this way, you will be able to boot your device into Fastboot Mode. OEM Unlocking, however, is required in order to unlock the bootloader.

To enable USB Debugging and OEM Unlocking, go to Settings > About Phone > Tap on Build Number 7 times, then go back to Settings > System > Developer Options.

 3: Unlock Bootloader on Pixel 7A

You will also need to unlock the bootloader of the device. Please keep in mind that doing so will result in the loss of all data on your device and void your warranty. Then please refer to our detailed guide on How to Unlock the Bootloader on Pixel 7A if that’s all well and good.
