Modern smartphones, despite the openness of the Android platform, are often limited by the manufacturer in user rights. Unlocking the bootloader is the first and most important step for those who want to fully control their device. The owner of Xiaomi Redmi 8 Pro may face the need to install custom firmware, obtain superuser rights or simply remove system debris that cannot be removed by standard means.
The procedure for removing restrictions requires carefulness and strict adherence to the algorithm of actions. Errors during the preparation stage can lead to blocking the Mi Account or, in the worst case, to turn the smartphone into a “brick.” However, if you follow all the instructions of the company’s engineers and use official tools, the risk is minimal. In this article, we will discuss in detail how to unlock the Xiaomi Redmi 8 Pro, what nuances should be considered and how to prepare the device for modifications.
Before you take action, you need to understand the consequences: unlocked bootloader opens the door to deep configuration of the system, but at the same time reduces the level of overall data security. Once the bootloader is unlocked, the encryption data protection function may stop working fully, making the phone vulnerable to physical access by attackers. In addition, some banking applications and services with high security requirements can cease to function correctly without additional manipulations to hide root rights.
⚠️ Attention: The bootloader unlock procedure results in the complete removal of all user data from the internal drive.Be sure to back up important photos, contacts and documents to an external medium or to the cloud before starting.
Preparation of the device and account Mi
The foundation of successful unlocking is the correct linking of the device to the account. Xiaomi security system requires that the smartphone be registered with the Mi Account system well before the procedure begins. Sign up for the phone settings by logging into your profile and make sure that the account status is active.
Then you need to activate the developer mode. To do this, go to the Settings → About menu and quickly click on the MIUI version seven times. Then a new option will appear in the expanded settings menu for developers. Go to it and find the option “Mi Unlock Status.” This is where the current status of the bootloader is displayed.
The same menu requires two critical functions to be enabled: OEM Unlocking and USB Debugging. Without activating these switches, your computer will not be able to communicate with your phone at the required level. Also make sure that the Wi-Fi settings include the option “Do not turn off Wi-Fi in sleep mode” so that the connection does not break at a critical moment.
☑️ Checking before unlocking
It's important to understand that there's a time to go from the first activation of Mi Unlock status, which usually takes 7 to 15 days, and if you try to unlock the device earlier, the tool will give you an error with the remaining latency, which is a measure of protection against device theft, so it's not legal to get around it.
Required tools and drivers
You will need a personal computer or laptop running Windows. Mobile unlocking methods are not provided by the manufacturer, so using third-party applications from the Play Market will not work. Download the official Mi Unlock Tool utility from miui.com/unlock.
The critical point is to install the correct ADB and Fastboot drivers. Without them, the computer will not see the phone in bootloader mode. It is recommended to install the universal Xiaomi USB Drivers package, which includes all the necessary components to communicate with the device in various modes of operation.
- 🔌 Use the original. USB-cable or quality analogue with support for data transfer, not just charging.
- 💻 Connect your phone directly to the port USB on the motherboard (back of the system unit), avoiding front ports and USB-hub.
- 🔋 Charge your smartphone to at least 60% to avoid a sudden shutdown during flashing.
Once you have the drivers installed, check them. Connect the phone in debugging mode and start the command line. Enter adb devices. If a device with a serial number appears on the list, then the connection is correct. If the list is empty or the list is displayed "unauthorized", check the phone screen - there should be a request for debugging permission, which must be confirmed.
💡
If drivers are not installed automatically, open Windows Device Manager, find an unknown device when your phone is connected in Fastboot mode, and manually specify the path to the driver folder.
The process of unlocking the loader
When you're done, you can go straight to unlock. Turn off the Redmi 8 Pro completely. Then press down the volume buttons and power buttons at the same time. Hold them until you see a picture of a hare in a cap repairing an android. That's Fastboot mode.
Connect your phone to your computer. Run the previously downloaded Mi Unlock Tool and log in to your Mi Account. The utility automatically detects the connected device. Press Unlock. The system will issue a warning that all data will be deleted and ask you to confirm the action.

Upon completion, the phone will automatically restart. The first boot after unlocking can take longer than usual, which is normal, since the system rebuilds the security sections.
⚠️ Note: Do not disconnect the cable during the unlocking process. USB and do not attempt to interrupt the utility, interrupting the recording of security keys can lead to permanent damage to the boot partition.
Comparison of Unlocking Methods
There are several approaches to removing restrictions, but not all of them apply to the Xiaomi Redmi 8 Pro. The official method through Mi Unlock is the only supported manufacturer. There are also informal methods that use CPU vulnerabilities (EDL mode), but they require disassembling the phone and the presence of special equipment.
Below is a table comparing the main characteristics of different approaches to unlocking:
| Method | The need for a PC | The risk of blocking | Guarantee |
|---|---|---|---|
| Official (Mi Unlock) | Yes. | Low. | Preserves* |
| EDL Mode (Test Point) | Yes. | High-pitched | Cancellation. |
| Paid services | No (remotely) | Medium. | Cancellation. |
Using paid services to unlock instantly often involves the risk of transferring account data to third parties.The official method, while waiting, ensures that you do not install malware on the device.

Possible errors and their solution
When you unlock, you often encounter common errors, and one of the most common is the "Couldn't verify device," which means that the account on the utility on your PC doesn't match the account you're tied to on your phone, and the solution is one: check your login and make sure that you're not logged in. SIM-card with the number to which the account is registered, installed in the phone or available for SMS reception.
The “Unlock failed (code: 10008)” error often indicates problems with the network connection or Xiaomi servers. DNS-servers on a computer on 8.8.8.8 or use mobile Internet instead of Wi-Fi. Sometimes the company's servers are overloaded, and the procedure is worth repeating after a few hours.
- 🔄 If the process is 50% or 99% frozen, don’t panic – wait up to 10 minutes before interrupting the process.
- 🔌 Try replacing it. USB-switch the cable or port if the device is permanently disconnected.
- 📱 Make sure that the date and time settings on your phone and computer are automatically synchronized.
If the utility produces an error that says "the account is not authorized," it means that not enough time has passed since the device was attached, in which case it remains only to wait, and attempts to deceive the system by changing the region or reassigning the account can reset the waiting timer.
💡
Most unlocking errors are not due to a phone malfunction, but to an unstable Internet connection or mismatch in Mi Unlock software versions. Always use the latest version of the program.
Actions after unlocking
Once successfully unlocked, you'll see the "Unlocked" message when you boot, as well as the open lock icon, and now the device is ready to install a customized Recovery, such as TWRP, which allows you to make full system backups, install modified firmware, and obtain Root rights through Magisk.
However, it is worth remembering security. With an open bootloader, anyone who gets physical access to your phone can try to reset the lock screen password or inject malicious code at a low level.
If you decide to return the device to its original state, you can lock the bootloader again through the command fastboot oem lock. But before that, be sure to install the stock official firmware corresponding to the region of the device.
