In this guide, we will list the steps to install the latest Nothing OS 3 based on Android 15 onto your CMF Phone 1 via Fastboot Commands. There exist two different ways of installing updates on your CMF device- via the official OTA Update APK file and using Fastboot Commands. The former is a straightforward method whereas the latter is a slightly technical one that even requires an unlocked bootloader. So why would one opt for the latter method? Well, it’s due to the plethora of benefits that it has to offer.
For starters, if your device is currently in a softbrick or bootloop state, then Fastboot is your only escape route. Likewise, if you would want to go back to the stock firmware from any Custom ROM, then the Fastboot Method is again the only way out. So owing to all these benefits involved, it is usually the preferred choice by tech enthusiasts. If you fall in this bracket as well, then let’s make you aware of the steps to install the latest Nothing OS 3 based on Android 15 onto your CMF Phone 1. Follow along.

Make sure to backup all the data on your device before installing any of these official builds. 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. 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 process.
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 the Bootloader on CMF Phone 1
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 Nothing and CMF Phone
