Sadique Hassan•Updated Apr 8, 2025

In this guide, we will show you the steps to install various Android 15/14 Custom ROMs on your Redmi Note 12 4G/5G. The newest addition to the Note series has grabbed the attention of the masses, not just for generic users but even for tech enthusiasts alike. This is because the Redmi series has always been known to be among the most active players in custom development and its twelfth iteration is no different either.

However, for some users, the underlying OS skin is not in sync with their requirements, mainly due to the fact that it’s bloated with tons of unnecessary preinstalled apps. Well, if you are of the same opinion as well, then this guide will give you a perfect platform to break free from the shackles of the stock MIUI ecosystem and welcome numerous AOSP-based ROMs that offer a clean, stock, fast, and stable usage experience. So without further ado, let’s get started.

Prerequisites to Installing Android 15/14 Custom ROMs on Redmi Note 12 4G/5G

Installing any of the below-listed ROMs will wipe off all the data from your device, so please take a 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 to install the ROM on the Redmi Note 12 4G/5G.

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.

STEP 3: Unlock Bootloader on Redmi Note 12 4G/5G

Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock Bootloader on any Xiaomi Device.
