How to unlock Xiaomi Redmi Note 8 Pro: official and alternative ways

The Xiaomi Redmi Note 8 Pro remains one of the brand’s most popular smartphones, but owners often face the need to unlock the bootloader.Without this, it is impossible to install custom software, obtain root rights or even update the firmware through fastboot in some cases. Unlike newer models, the Note 8 Pro has its own nuances: it uses a Mediatek Helio G90T processor, not a Snapdragon, which affects the unlock algorithm.

This article covers the most current ways to unlock for 2026, including the official method through the Mi Unlock Tool, bypassing latency restrictions and solving typical errors (for example, Couldn’t unlock or Current account is different from the account info on the device). We will also discuss what data will be deleted after unlocking, how to save it. IMEI Why some “gray” methods can lead to an irreversible block of your Mi Account.

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

Factory lock bootloader on Xiaomi devices is a security measure that:

• 🔒 Prevents the installation of unofficial firmware (including LineageOS or Pixel Experience).
• 🛡️ Protects against hacking through vulnerabilities in fastboot or recovery.
• 📱 Guarantees Mi Cloud, Find Device and other branded features.

However, blocking creates problems if you want to:

• ⚡ Install TWRP Recovery for backups or manual upgrades.
• 🔧 Get root rights through Magisk.
• 🔄 Swipe global firmware on a device with a Chinese version (CN ROM).
• 🐌 Speed up your smartphone by removing unnecessary system applications (bloatware).

⚠️ Warning: Unlocking the bootloader erases all data on the device, including photos, contacts and apps. Even if you backup through the Mi Cloud, some settings (such as game data) may not recover.

On the Redmi Note 8 Pro, the process is complicated by the fact that Mediatek processors require additional authorization when running through the SP Flash Tool.This means that “bypass” unlock methods (for example, through Deep Testing) may not work stable or at all suitable for this model.

Unlocking with Mi Unlock Tool

The only method Xiaomi supports is using the Mi Unlock Tool, which takes 7 to 360 hours (depending on Xiaomi’s policy at the time of unlocking) and requires you to link your Mi Account to your device.

Requirements for official unlocking:

• 📱 Smartphone Redmi Note 8 Pro with version MIUI 10.3.5.0 (older versions may require an update).
• 🔌 Battery charge of at least 60%.
• 🌐 A stable Internet connection (preferably over Wi-Fi).
• 🖥️ Windows computer 7/10/11 (on macOS/Linux Mi Unlock Tool is not working).
• 🔑 Mi Account tied to the device for at least 7 days.

Step-by-step:

1. Activate Developer Options: Go to Settings → About Phone → MIUI version and tap it 7 times until the notification “You’ve become a developer” appears.
2. Enable USB Debugging and OEM Unlock: Go to Settings → Additional → For Developers and activate both.
3. Link your Mi Account to your device: In the same Developer Menu, find Mi Unlock Status and click Add Account and Device.
4. Download the Mi Unlock Tool from the official website (version should not be older than 5.5.224.30).
5. Connect your smartphone to your PC in fastboot mode: Turn off your phone, then press Volume Down + Power until a hare in a hat-eared appears.
6. Launch the Mi Unlock Tool, log in to your Mi Account and follow the program instructions.

Once successfully unlocked, the phone will automatically restart and reset to factory settings. Now you can flash TWRP or custom firmware.

⚠️ Note: If the Mi Unlock Tool gives you a Couldn't unlock error of 50% or 100%, it means that the wait time has not expired. Check the unlock status in the developer settings - there will be the remaining period (for example, 168 hours).

Alternative methods of unlocking (at your own risk)

If the official method is not suitable (for example, due to a long wait), there are "grey" methods. They may work, but they are fraught with:

• 🚫 Mi Account block (if Xiaomi suspects fraud).
• 🔧 Loss of guarantee.
• 📵 «The “device” of the device (if the process is interrupted).

Method 1: Unlocking through Deep Testing (for older versions of MIUI)

2. Install APK on your phone and launch the app.
3. Follow the instructions inside (usually you need to enter the code received via SMS).
4. After successful activation, restart to fastboot and use the Mi Unlock Tool – the wait time will reset to 0 hours.

Method 2: Bypassing EDL-The mode (only for experienced users)

EDL (Emergency Download Mode) allows you to flash your device directly through the Qualcomm port, but on the Redmi Note 8 Pro (with Mediatek), this method requires:

• 🔧 Special cable (EDL cable) or circuits of the circuit board.
• 💻 Programme programmes SP Flash Tool and Authorization File (Auto File).
• 📄 Firmware in.scatter format.

The firmware process through EDL:

1. Put your phone in EDL mode (usually close the test points on the board or use the adb reboot edl command if supported).
2. Connect the device to the PC – Mediatek Preloader should appear in Device Manager.
3. Launch the SP Flash Tool, download the scatter-file and start firmware.

⚠️ Note: Incorrect Firmware Through EDL may result in loss IMEI If you're not sure what you're doing, you can call a service center.

Typical errors and their solutions

When you unlock the Redmi Note 8 Pro, users often encounter errors, and here are the most common ways to fix them:

Additional advice:

• 🔄 If the Mi Unlock Tool is 99% down, reconnect. USB-cable or change port.
• 📡 Use the original Xiaomi cable – cheap analogues can cause data transmission errors.
• 🕒 If the wait time is reset to 0 hours, but the unlock does not pass, try changing the region of the Mi Account to China (sometimes helps).

💡

2. If you plan to flash custom firmware, choose one that supports Mediatek Helio G90T (such as Havoc-OS or Corvus OS).
