Hey guys! Unlocking the bootloader on your Poco M4 Pro 5G opens up a world of possibilities, from flashing custom ROMs to rooting your device and tweaking it to your heart's content. While it might sound intimidating, it's actually a pretty straightforward process. This guide will walk you through each step, making sure you don't miss anything.

Why Unlock Your Bootloader?

Before we dive in, let's quickly cover why you might want to unlock your bootloader in the first place.

• Custom ROMs: Custom ROMs can offer improved performance, newer versions of Android, and unique features not found in the stock MIUI software. Unlocking your bootloader is the first step to installing these ROMs.
• Rooting: Rooting gives you superuser access to your device, allowing you to modify system files, install advanced apps, and remove bloatware. Again, bootloader unlocking is usually a prerequisite.
• Custom Recoveries: Custom recoveries like TWRP allow you to create full system backups, flash ZIP files, and perform other advanced tasks.
• Tweaking and Customization: Want to push your phone's performance or customize every aspect of the user interface? Unlocking the bootloader allows for deep-level tweaking.

However, there are a few important things to keep in mind before proceeding:

• Warranty: Unlocking your bootloader may void your warranty. Check with Xiaomi's warranty policy in your region.
• Data Wipe: The unlocking process will wipe all data on your phone. Back up everything important before you start.
• Security Risks: Unlocking your bootloader can make your device more vulnerable to security threats if you're not careful about what you install.

Prerequisites

Okay, let's get started. First, make sure you have everything you need:

1. A Windows PC: The unlocking tool is designed for Windows.
2. Poco M4 Pro 5G: Obviously!
3. USB Cable: A good quality USB cable to connect your phone to your PC.
4. Mi Unlock Tool: Download the latest version from Xiaomi's website.
5. ADB and Fastboot Drivers: These are essential for communicating with your phone in fastboot mode. You can download them separately or as part of the Android SDK Platform Tools.
6. Xiaomi Account: You'll need a Xiaomi account and it needs to be logged in on your phone.

Step-by-Step Guide

Now for the fun part! Follow these steps carefully:

1. Enable Developer Options and USB Debugging

• Go to Settings > About phone. Tap on MIUI version seven times until you see a message saying "You are now a developer!".
• Go back to Settings, then Additional settings > Developer options.
• Enable OEM unlocking. This is crucial!
• Enable USB debugging. You'll be prompted to allow USB debugging when you connect your phone to your PC later. Always allow it from your computer.
• Enable Allow bootloader unlocking. This option might not be present on all devices, but if it is, make sure it's enabled.

2. Link Your Xiaomi Account

• In Developer options, find Mi Unlock status. Tap on it.
• You'll need to add your Xiaomi account and associate it with your device. This process requires mobile data, so make sure your Wi-Fi is turned off. Tap Add account and device and follow the instructions.
• You might get an error message saying "Couldn't add. Wait a minute or two and try again." Just keep trying, it usually works after a few attempts. This is a common issue, so don't panic!

3. Boot into Fastboot Mode

• Power off your Poco M4 Pro 5G.
• Press and hold the Power button and Volume Down button simultaneously until you see the fastboot screen (a rabbit fixing an Android).

4. Unlock with Mi Unlock Tool

• Extract the Mi Unlock Tool ZIP file on your PC and open the folder.
• Run the miflash_unlock.exe file.
• Sign in with the same Xiaomi account you linked on your phone.
• Connect your phone to your PC using the USB cable.
• The Mi Unlock Tool should detect your device. If it doesn't, make sure you have installed the ADB and Fastboot drivers correctly.
• Click the Unlock button. You'll see a warning message. Read it carefully and click Unlock anyway (or similar wording). Remember, this will wipe your data!
• The unlocking process will begin. It usually takes a few minutes. The tool will display a countdown.

5. The Waiting Game

Xiaomi imposes a waiting period before you can actually unlock your bootloader. This waiting period can range from a few hours to 15 days! The Mi Unlock Tool will tell you how long you need to wait. This is a security measure implemented by Xiaomi.

6. Unlock Again (After Waiting)

Once the waiting period is over, repeat steps 3 and 4. This time, the unlocking process should complete successfully without any further delays.

7. Bootloader Unlocked!

Your Poco M4 Pro 5G should now reboot. The first boot after unlocking can take a bit longer than usual. You'll see an unlocked padlock icon during boot, indicating that the bootloader is unlocked.

Troubleshooting

Here are some common issues you might encounter and how to fix them:

• "Couldn't add. Wait a minute or two and try again.": This is a common issue when linking your Xiaomi account. Just keep trying, and make sure you're using mobile data.
• Device not detected by Mi Unlock Tool: Make sure you have installed the ADB and Fastboot drivers correctly. Try restarting your PC and phone.
• Stuck at 99%: This can happen if your Xiaomi account isn't properly linked or if there are issues with the servers. Double-check your account and try again later.
• Error messages: Read the error message carefully and search online for solutions. The XDA Developers forum is a great resource.

Verifying Unlock Status

To confirm that your bootloader is indeed unlocked:

• Boot into fastboot mode (Power + Volume Down).
• Open a command prompt or terminal on your PC and navigate to the folder where you have ADB and Fastboot installed.
• Type the command fastboot devices. If your device is listed, it's connected properly.
• Type the command fastboot oem device-info. Look for the line that says "Device unlocked: true".

Next Steps

Congratulations! You've successfully unlocked the bootloader on your Poco M4 Pro 5G. Now you can explore the world of custom ROMs, rooting, and other advanced modifications. Remember to proceed with caution and always back up your data before making any changes to your system.
