Owning a Xiaomi Redmi Note 9 offers a lot of customization options, but the standard MIUI shell often restricts access to system files. Full freedom of action begins with obtaining the rights to change the system partition, which is impossible without the prior procedure of unlocking Bootloader. This is a critical stage for those who plan to install custom recaps, obtain super-user rights or change the firmware region.
This process is not instantaneous and requires a strict sequence of actions, because the Mi Account security system imposes time constraints. Ignoring the preparatory stages can lead to a smartphone freeze in Fastboot mode or complete loss of data stored in the device’s memory. In this article, we will analyze each step in detail to minimize risks and successfully complete the procedure.
It should be noted that interference with the bootloader is officially authorized by the manufacturer, but it has certain consequences that you need to know about in advance, the main one being the complete cleaning of the device’s internal memory at the time of unlocking, so creating a backup is not just a tip, but a mandatory requirement before starting work.
⚠️ Note: After unlocking the bootloader, some high-security banking applications and services (such as Google Pay) may stop working properly without additional manipulations to hide root rights.
Why you need to unlock and what risks exist
The main reason Redmi Note 9 users are eager to unlock the bootloader is to gain full control of the operating system. Standard mode restricts access to root directories, preventing them from removing system debris or installing deep interface modifications. Open bootloader allows custom firmware such as LineageOS or Pixel Experience, which can significantly improve the autonomy and performance of the device.
However, the procedure also carries certain risks, primarily related to data security: once restrictions are lifted, the device becomes more vulnerable to malware if the user does not have sufficient knowledge of digital hygiene.
It is important to understand the difference between an unlocked bootloader and the rights that Root has obtained. Unlocking only opens the door to modifications, but does not automatically allow access to system files. Full system management will require installing a rights manager such as Magisk, which is the next step after the successful completion of the procedure in question.
- 🔓 Possibility of installing custom recavers (TWRP, OrangeFox) to create full system backups.
- 🚀 Removal of preinstalled advertising software and system applications that cannot be removed by standard methods.
- 🎨 Deep customization of the interface, including changing fonts, animations and system files.
- ⚠️ The risk of turning a smartphone into a “brick” with incorrect firmware of incompatible files.
Despite the potential challenges, the development community around Xiaomi is huge, allowing for quick solutions to any problems that arise, and statistics show that most errors occur during the preparation stage, when users neglect to check the compatibility of drivers or software versions.
Preparatory stage: accounts and backup
The first and most important step is to link the device to the Mi Account. Without active authorization in the system, the Mi Unlock Tool will simply not see the smartphone or give an authorization error. You need to go to the settings of the smartphone, select the item "Mi Account" and log in under your data, making sure that synchronization is enabled.
In parallel with this, you should activate the developer mode and allow debugging by USB. To do this, you need to click on the build number several times in the About Phone section, after which the corresponding item will appear in the Advanced Settings menu. USB-Debugging and, critically for the Redmi Note 9, enabling the option "Factory Unlock".
☑️ Checklist of smartphone preparation
Don’t forget to back up, as the unlocking process initiates a complete reset of the device to factory settings. You can use the built-in Mi Cloud or third-party solutions like Google Drive to save contacts, photos and a list of installed applications. Once reset, data recovery will take time, so it’s better to transfer heavy files to your computer in advance.
⚠️ Warning: Make sure you remember the password from your Mi Account. Once unlocked, the smartphone will require you to enter this data on your first run as a protection against theft.
Installation of drivers and utilities Mi Unlock on PC
To interact with a smartphone at the bootloader level, you will need a computer running the Windows operating system. On macOS or Linux, the procedure is possible, but requires the use of command line and emulators, which is much more difficult for a beginner. On a PC, you need to install current ADB and Fastboot drivers that ensure correct device recognition in various modes of operation.
The official unlock utility is called Mi Unlock, which should be downloaded exclusively from the official en.miui.com/unlock website to avoid malicious code, and once the archive is uploaded, it should be unpacked into the root directory of the disk, such as the C:\MiUnlock folder, so that the path to executable files does not contain Cyrillic characters that can cause errors in the operation of scripts.
When you first start the program, you will need to log in under the same Mi Account that was used on your smartphone. If the accounts do not match, the process will be blocked, and the utility will check for updates for itself and drivers, agree to install them to ensure the stability of the connection.
- 💻 Download Mi Unlock Tool only from the official Xiaomi resource.
- 🔌 Use the original. USB-cable or quality analogue with data transmission support.
- 📂 Unpack the program in a folder with a path that does not contain Russian letters.
- 🔋 Make sure that all Windows updates are installed on your computer.
In some cases, antivirus software may block drivers from working, considering them suspicious due to deep access to the system, it is recommended to temporarily disable protection or add a folder with a utility to exceptions to avoid interrupting the process at a critical stage.

Application and waiting for the release date
Xiaomi’s policy is to have a mandatory waiting period after applying for an unlock, which is required to verify the user’s activity and confirm that the user is aware of his actions. For new accounts, this period can be from 7 to 168 hours (7 days), while for authoritative users it can be reduced.
After entering the utility Mi Unlock and connecting the smartphone in Fastboot mode (clamping the keys Volume Down) + Power), press the "Unlock" button. If the account is tied less than 7 days ago, the system will tell you to wait. During this period, it is strongly recommended not to leave the account on your smartphone or reset the settings, as the timer may reset.
There is a myth that active use of the smartphone during this period (calls, the Internet, games) accelerates the process. In fact, Xiaomi servers operate on an automatic algorithm, and the user can not influence it. The main thing is to wait for a notification in the program on the PC or in the system notification of the smartphone that the status of the account has changed.
| Account status | Waiting time | Probability of success | Features |
|---|---|---|---|
| New account | 168 hours (7 days) | Tall. | Active is required. SIM-map |
| Account with history | 0 to 7 days. | Very high. | Depends on MIUI activity |
| Repeated application | 30 days of lockdown | Medium | With frequent attempts to dump |
| Region China | Not applicable. | Low. | Requires special permission |
During the waiting period, you can safely use your phone in normal mode, the only limitation is that you can not delete the Mi Account from the device settings, otherwise the binding will disappear and the procedure will have to start again. After the timer expires, Mi Unlock will allow you to complete the procedure instantly.
💡
Tip: Don’t try to bypass the timer by waiting using third-party paid services. 90% of the time it’s a scam, as the restriction is set on the server side of Xiaomi and is independent of the user’s actions.
Step-by-step process of unlocking the loader
When the wait period has expired, you can start the final stage. Connect the Redmi Note 9 to your computer when it's off, holding the volume button. The Fastboot logo should appear on the screen with the image of a rabbit fixing an android. Make sure that the Mi Unlock program has a green connection indicator on.
Press the Unlock button in the utility, you'll see a warning that all data will be destroyed, you'll confirm the action, you'll start the unlock process, which will take 10 to 60 seconds, and at that time, the progress bar will be displayed on the smartphone screen, and the text log of the commands that are executed on the computer.
Connecting to device...
Account connected.
Device unlocked successfully.Once the process is complete, the phone will automatically restart. The first boot after unlocking will take longer than usual - from 5 to 10 minutes. Don't be alarmed if the device hangs on the MI or Android logo for a long time; this is normal behavior when initializing a new security configuration.
- 🔄 Wait for the message "Unlocked" in the program on PC.
- ⏳ Do not disconnect the cable until the system is fully restarted.
- 📱 Go through the initial Android setup as on a new device.
- ✅ Check the status in Fastboot mode (it should say "Unlocked").
If the process is interrupted at 50% or 99%, don't panic. USB-Try reconnecting the cable to another port (preferably) USB 2.0) and try again without leaving Fastboot mode.
⚠️ Warning: After successful Fastboot unlocking, the orange "Unlocked" logo will appear under the logo, which is normal, indicating that restrictions have been lifted, not broken.
Solving Typical Errors and Problems
One of the most common errors is the message “Couldn’t verify device”, which means that the utility can not match the device with the account, the solution lies in checking the Internet on the PC and smartphone (via Wi-Fi or mobile network before entering Fastboot mode), as well as in reassigning the account in the developer settings.
The “Unlock failed (error code: 10008)” error often indicates problems with Xiaomi servers or incorrect system time. Check that the date and time on the computer are synchronized with the Internet. Also try running the utility on behalf of the administrator and using another browser to log in to your account if the program offers web authorization.
If the phone went into an endless restart (bootloop) after trying to unlock, you will need to flash the stock version through the Mi Flash Tool. This will return the device to factory condition and possibly lock the bootloader again, but save the device from complete failure.
💡
The main reason for most mistakes is unstable. USB-Connecting or using a non-original cable, replace the wire with a high-quality, thick-veined cable that can transmit data, not just charge the device.
Redmi Note 9 (Global, India, China) models can have nuances in the procedure, for example, Indian versions sometimes require a wait of up to 15 days.
