Unlocking the Xiaomi Redmi Note 8 Pro bootloader: a complete guide with error solutions

The Xiaomi Redmi Note 8 Pro (codenamed begonia) is still a popular device among custom firmware enthusiasts, despite the release of new models. The main barrier to installing alternative software is the blocked bootloader, which Xiaomi blocks by default. Unlocking opens access to the installation of TWRP, custom cores, LineageOS and other modifications, but the process is fraught with official restrictions and potential risks.

Unlike newer models (such as the Redmi Note 12 Pro+), where unlocking can take up to 360 hours to wait, the Note 8 Pro has a simpler procedure — but requires precise follow-up. In this article, we will discuss the official method through the Mi Unlock Tool, avoiding common bugs (such as Couldn’t unlock or This device is locked), as well as alternative ways for power users.

Why you need to unlock the bootloader on the Redmi Note 8 Pro

A blocked bootloader is a protective mechanism that prevents:

• 🔄 Installation of unofficial firmware (Custom) ROM), The Pixel Experience or Havoc OS.
• 🔧 Modifications to system files (e.g., deleting bloatware or modifying build.prop).
• ⚡ Use of custom cores to overclock the processor (MediaTek Helio) G90T) or improving autonomy.
• 🛠️ Restore the device through TWRP when "brick" (for example, after a failed update).

Without unlocking, you are limited to stock MIUI even if you want to:

• 📱 Install Google Camera (GCam) with Night Sight support.
• 🔒 Remove ads in system applications (for example, in Mi Browser or Mi Video).
• 🔄 Update to a more recent version of Android (official support for Note 8 Pro ended on Android 10).

⚠️ Warning: Unlocking the bootloader resets the device to factory settings and deletes all data, including files on internal memory. Also, this will void the warranty if it is still valid. Before starting the procedure, back up via Mi Cloud or manually.

Preparation for Unblocking: Requirements and Warnings

Before starting the procedure, make sure that all the conditions are met:

1. Mi Account: You must have a Mi-account tied to the device for at least 72 hours (3 days).This is Xiaomi's rule for theft protection. If the account is new, unlocking will not be available.
2. MIUI Version: The device should run on official firmware (not custom!). Check Settings → About Phone → MIUI Version. For the Note 8 Pro, the current versions are MIUI 12.5 or MIUI 13 (based on Android 10).
3. Battery charge: At least 60%. When discharging during the procedure, the device can go into EDL (emergency firmware) mode.
4. Cable and PC: Use the original USB-C cable and USB 2.0 port on your computer (problems with USB 3.0 are common).

Also check if your Note 8 Pro is tied to a carrier (such as MTS or Beeline) and devices with "operator" firmware may require additional steps.

⚠️ Note: If you have previously tried to unlock the bootloader and received a Couldn't unlock error of 50% or 100%, this means that the device is locked for 30 days.

Step 1: Enabling Developer Mode and Permits

To unlock the bootloader, you first need to activate hidden settings for developers:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row, and a notification will appear: You became a developer!

Once OEM Unlock is enabled, the device can request confirmation via Mi-account. Enter the password from the account associated with the phone.

💡

If the OEM Unlock option is inactive (grey), it means that the account is not tied to the device for long enough (less than 72 hours) or that an unofficial firmware is used.

Step 2: Install drivers and Mi Unlock Tool

2. Connect the Note 8 Pro to your PC in fastboot mode (turn off the phone, then press Volume Down + Power before the Fastboot logo appears).
3. Open Device Manager on PC. Android should appear in the Other Devices section with an exclamation point.

Alternative Unlocking Methods (If Mi Unlock Tool is Not Working)

If the official method has not worked (for example, because of a 30-day lock), you can try workarounds, which require more technical training and are risky, but sometimes the only solution.

Method 1: Use of the EDL-The mode (for experienced users)

• 📱 Install TWRP: Castom Recovery will allow you to create backups and sew Custom ROM. For the Note 8 Pro the current version — TWRP 3.7.0 from mauronofrio.
• 🔄 Swipe custom firmware: Popular options - Pixel Experience (pure Android), Havoc OS (maximum customization or LineageOS (stability).
• 🔒 Remove Bloatware: With the help of ADB or TWRP You can remove unnecessary system applications (e.g. Mi Browser, Mi Music).
• ⚡ Swipe through the custom core: For example, Kernelsu for performance improvement or FrancoKernel for charge saving.

Important warnings:

• 🚨 Installing unofficial software can lead to data loss, overheating or unstable operation.
• 🔋 Some firmware (for example, based on Android 11)+) You may not be able to support MediaTek Helio G90T full-capacity.
