Crdroid Bootimg Install Guide

How to Install the crDroid Boot Image: A Step-by-Step Guide

Installing a custom ROM like crDroid is one of the best ways to revitalize your Android device, offering features and customization options that stock firmware often lacks. However, with modern Android architecture (especially on devices launching with Android 11, 12, or 13), the installation process has evolved.

Gone are the days of simply flashing a ZIP file. Modern installations often require flashing a specific boot image (or vendor_boot image) before you can even access the recovery to install the ROM.

This guide will walk you through what a boot image is, why you need it for crDroid, and how to install it safely using Fastboot.
