While Android is based on Linux, most phones come with a version that is heavily tied to Google’s proprietary apps and services, which collect a vast amount of personal data. Fortunately, you can reclaim your privacy and extend the life of your hardware by replacing the manufacturer’s operating system with an open-source alternative like LineageOS. This guide will walk you through the general process and what you need to know before you begin.

Why Replace Your Phone’s OS?
- Privacy: Escape the constant data collection from Google services. From the moment you enter your credentials, data like search history, GPS location, and contacts are shared with the company.
- Security and Longevity: Manufacturers often stop providing updates for older hardware, leaving devices vulnerable to security threats. Projects like LineageOS provide the latest Android features and security fixes for devices that manufacturers have abandoned.
- Freedom from Bloatware: Enjoy a clean Android experience without the non-removable proprietary apps (G-Apps) that come pre-installed.
Before You Start: An Important Warning
Replacing the OS on your primary phone is a serious undertaking and should be done with care.
- Warranty Void: The process requires unlocking your phone’s bootloader, which will void your warranty.
- Risk of Bricking: Installing the wrong software build for your device can render it permanently unusable (‘bricked’).
- Data Loss: Unlocking the bootloader will completely wipe all data from your device, so a thorough backup is essential.
- App Compatibility: Some apps, particularly banking apps and certain games, may not work on a device with an unlocked bootloader.
The General Installation Process
The exact steps vary wildly between devices, so you must follow the specific guide for your model on the LineageOS wiki (https://wiki.lineageos.org/devices/). However, the general process is as follows:
- Enable Developer Options: On your phone, go to Settings > About Phone and tap repeatedly on the ‘Build number’ or equivalent until Developer Mode is enabled.
- Enable OEM Unlocking: In the new Developer Options menu, enable ‘OEM Unlocking’ and ‘USB Debugging’.
- Unlock the Bootloader: This is the most device-specific step. It often involves getting an unlock code from the manufacturer’s website using a token from your device. This process will wipe your device’s data.
- Install a Custom Recovery: You will flash a custom recovery environment, like TWRP or Lineage Recovery, onto your phone using tools like ADB and Fastboot from your computer.
- Sideload the ROM: From the custom recovery menu, you will use ADB to ‘sideload’ the LineageOS ROM file (a .zip file you downloaded earlier) from your computer to your phone.
- Reboot: Once the installation is complete, you can reboot your phone and enjoy your new, de-Googled operating system.
