How to find out if the bootloader is unlocked on the Xiaomi Redmi Note 8 Pro: 5 proven ways

Introduction: Why Check the Status of a bootloader on the Redmi Note 8 Pro

The bootloader on Xiaomi smartphones is a software component that controls the process of launching the operating system. On Redmi Note 8 Pro devices, it is blocked by the manufacturer by default. Unlocking opens access to custom firmware installation, root rights or brick restoration, but simultaneously deprives warranties and increases security risks.

Before buying a used phone, trying to flash alternative software, or selling your device, it is important to know exactly the status of the bootloader. Status errors can lead to the inability to install official updates, MIUI malfunctions, or even a complete loss of smartphone performance. In this article, we will analyze all the current methods of verification, from visual signs to commands via ADB.

Method 1: Checking through Fastboot mode (the most reliable method)

Fastboot mode is a low-level interface that allows you to interact with the bootloader directly. On the Redmi Note 8 Pro, it is entered by a combination of buttons, and the lock status is displayed as a text message, which works even on “bricks” (non-booting devices).

To check the status:

1. Turn off the phone (hold the power button for 10-15 seconds).
2. Press Volume Down + Power at the same time and hold for 5-7 seconds until the Fastboot logo appears (the Mi Bunny robot labeled FASTBOOT).
3. Connect your smartphone to your computer via the original USB cable (USB-C port).
4. One of the two inscriptions will appear on the screen: 🔓 Unlocked – the bootloader is unlocked. 🔒 Locked – the bootloader is blocked.

⚠️ Note: Some firmware (e.g. global) MIUI 12.5+) The inscription may not be there. In this case, use the method of ADB (see section 3).

Method 3: Checking through ADB (for power users)

The ADB (Android Debug Bridge) tool allows you to send commands to a device via a computer, which is more accurate than visual signs and works even if the phone is loading, but the status of the bootloader is not obvious.
