In this guide, we will show you the steps to install the latest LineageOS 21 based on Android 14 onto your Redmi Note 10 Pro/Max. Well well, who saw it coming? It has only been a week or so since the official release of Android 14 and the custom ROMs are already lining up!

At the time of writing, LineageOS has already stepped its feet in this domain. For the unaware, this ROM offers a de-Googled ecosystem with just the crucial features. So a clean stock system without any bloatware coupled with a fast and snappy OS is on the cards. Add to it, a few tweaks of the latest OS build, and you couldn’t have asked for more! So without any further ado, let’s get started with the steps to install LineageOS 21 Android 14 on Redmi Note 10 Pro/Max.

At the time of writing, the ROM is an unofficial build and is in the testing phase, so you might occasionally come across a few bugs and issues. Moreover, as of now, the ROM has included GApps for testing [so you may skip Step 10 for now]. Once it moves over to the official build, it will only be a Vanilla build. So keep these points in mind while flashing it.
Moreover, the process will wipe off all the data, 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
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.

STEP 2: Enable USB Debugging and OEM Unlocking

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.
So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
STEP 3: Unlock Bootloader on Redmi Note 10 Pro/Max
