Before we dive in, it’s essential to understand that unlocking the bootloader is irreversible in terms of warranty, but you can re-lock it if necessary. This guide is specifically for the OnePlus 3, so do not attempt these steps on any other device.

Unlocking the bootloader on your OnePlus 3 will allow you to install TWRP, flash custom ROMs, and gain root access. However, it’s important to remember that this will void your warranty. If you choose to proceed, this guide will take you through each step to ensure a successful bootloader unlock.

What is a Bootloader?

A bootloader is a piece of code that runs when you power on your device. It initializes the hardware and loads the operating system (OS) kernel. For Android devices, the bootloader is typically locked by manufacturers to prevent users from modifying the OS. Unlocking the bootloader grants you the freedom to customize your device by flashing custom recoveries, ROMs, or rooting the device. However, unlocking the bootloader also voids the warranty and poses the risk of bricking the device if not done correctly.

Important Considerations

Before proceeding, be aware that unlocking the bootloader will erase all data on your device. It’s crucial to back up all your important data before starting. Additionally, unlocking the bootloader will void your warranty. If you’re comfortable with these risks, follow the steps below to unlock your OnePlus 3 bootloader.
