How to Install various Custom ROMs on Pixel 7A

Sadique Hassan•Updated Dec 28, 2023

In this guide, we will show you the steps to install numerous custom ROMs on your Pixel 7A. The devices from the Silicon Valley giant have always been known to be among the most active players in custom development. And the latest entry to the Pixel lineup, the affordable 7A, has once again done justice to this statement, and in quite some style. Within days of its launch, a couple of custom ROMs have already made their way over to this device.

But why is there a need to ditch the Pixel ecosystem and opt for a custom ROM when the latter are themselves based on AOSP? Well, one major reason for the same is the plethora of additional mods and tweaks that these ROMs behold [while you could try out most of these features in a stock ROM as well, but then you’ll have to root your device]. So on that note, let’s get started with the steps to install numerous custom ROMs on your Pixel 7A.

How to Install Various Custom ROMs on Pixel 7A

Irrespective of the ROM you end up flashing, each of them will wipe off all the data from your device, so please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Install Android SDK

install adb platform tools windows

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 2: Enable USB Debugging and OEM Unlocking

Next up, you will also have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking.
