Owners of Xiaomi, Redmi and POCO smartphones often face the need to expand the functionality of their device, and the first step in this process is to unlock the bootloader. Many users are looking for information about where to enter the so-called Xiaomi unlock code, mistakenly believing that this is a special combination of numbers entered into the phone field, like code from the network. In fact, the process of unlocking Bootloader in the MIUI and HyperOS ecosystem is built differently and requires interaction with the manufacturer’s computer and servers.
Understanding where to type your data is critical to avoid locking your device or losing warranty. Unlike older phones, today’s gadgets use a digital link to your Mi Account, which is the main key, not the abstract numerical code you find on the Internet. In this article, we’ll take a closer look at the architecture of the unlock process and specify the exact locations where to enter the required parameters.
The procedure is fast and requires preparation, because the wrong actions can lead to the inability to boot the operating system. The unlock code is not entered in the dial menu or in the locking field of the smartphone screen, it is processed remotely by the company's server after checking the access rights. Let's take a Step-by-step, how this path goes and what tools you will need to successfully complete the operation.
⚠️ Warning: Unlocking the bootloader results in the complete removal of all user data from the device.Be sure to back up important information to a cloud server or external media before starting the procedure.
What is Xiaomi unlock code and how does it work?
The term “unlock code” in the context of Xiaomi devices is often misleading for beginners. In the classical sense of unlocking phones, this means a digital key that removes the restriction on working with the user. SIM-However, when it comes to system modifications and custom firmware installation, the unlock code is a digital certificate linked to your Mi Account and unique device identifier (IMEI).
The security mechanism is built on the principle of a trusted account. You don't manually enter the code into the phone; instead, you log in to a special utility on a PC that sends a request to the Xiaomi server. The server checks whether the account is linked to that particular device and how long it has been since the link. If all the conditions are met, the server sends a command to unlock, not a text code.
- 🔑 Mi Account is your digital passport that needs to be active and linked to your device.
- ⏳ Waiting timer – the period to wait (usually 168 hours) after filing an application for unlocking.
- 💻 Mi Unlock Tool is the official intermediary program through which keys are exchanged between the phone and the server.
It is important to understand that there is no universal code for all Redmi Note or Xiaomi Mi models. Each request is individual. The Bootloader security system checks the digital signature, and trying to enter arbitrary values into the program fields will only lead to an authorization error. The success of the operation depends on the correctness of the account data and compliance with the time frame set by the manufacturer.
⚠️ Note: Using third-party paid services that promise instant unlock without waiting for a timer can lead to a device locking on the device. IMEI Be careful about transferring your credentials to third parties.
Where to enter data to unlock
The most common question users ask is, “Where to enter the code?” The answer is unequivocal: the only place where you enter data to unlock is the official Mi Unlock Tool, running on a Windows computer. No menus inside the smartphone itself (neither the engineering menu nor the developer’s settings) contain fields for manually entering unlock code as usual.
The way you enter data is this: once you connect your smartphone in Fastboot mode to your computer, you launch the program and log in to your account. It's in the program window, in the login and password fields, you "enter" your credentials. Once you press the "Unlock" button, the program itself generates a request containing all the necessary hashes and identifiers, and sends them to the server.
If you see a field to enter the code, it can mean one of two things: either you try to enter the confirmation code that came to the SMS or to the email to log in to your Mi Account, or you use unofficial software. In the official scenario, everything happens automatically. The program itself considers the Device ID and sends it for verification.
What if the program asks for a verification code?
Sometimes users confuse unlocking the bootloader with unlocking the screen or Mi Account after reset. In the latter case, the code or password is entered directly on the lock screen of the smartphone after the reboot. But only desktop software is used to access the Bootloader. You can not unlock the bootloader simply by typing a command into the ADB or terminal without going through the authorization utility.
Step-by-step instructions for obtaining permission
Before you can unlock the device, you need permission from Xiaomi. It's not an instantaneous process, and it requires a number of conditions. First, you need to register your Mi Account and link your phone number to it, then you need to turn on the device in the Developer menu, and you need to link the account to the device.
Once anchored, the system will start a countdown. The standard waiting time is 168 hours (7 days), but in some regions or for certain models, it can be increased to 360 hours or even 30 days, during which time you can not log out of your account on your phone and reset your settings, otherwise the timer will reset.
☑️ Checklist of preparations for unlocking
There is also a way to get "Beta tester" status in the Mi Community, which sometimes (but not always) reduces latency or accesses early versions of the software. However, the main path for all users is waiting. Attempts to cheat the system by changing the date on the device or using modified versions of Mi Unlock most often lead to errors or account bans.
| Phase | Action. | Where it's done |
|---|---|---|
| 1. Registration | Creating a Mi Account | Mi.com website or phone settings |
| 2. Tethering | Enable "Mi Unlock status" | Menu "For developers" in Android |
| 3. Waiting | Timer shutter speed (168+ hours) | Automatically on Xiaomi server |
| 4. Unlocking | Pressing the Unlock button | Mi Unlock Tool for PC |
It is important to monitor the status of the application. Sometimes, especially during the release of new versions of Android, servers can be overloaded and the verification process can be delayed. In such cases, Mi Unlock may display a message that permission has not been obtained yet, even if 7 days have passed, in which case you can only wait.
Use of the Mi Unlock Tool Program
The main tool for interacting with the bootloader is the Mi Unlock Tool, which is only available for the Windows operating system. Once you download and install the program, run it on behalf of the administrator. The first step is authorization: enter the username and password from your Mi Account. This is where, in the fields of the program, you enter your credentials.
Next, you need to transfer the smartphone to Fastboot mode. To do this, the device turned off, you need to press the volume and power buttons simultaneously until the image of a rabbit repairing an android appears on the screen, or the inscription FASTBOOT. Connect the phone to the computer with the original cable. The program must determine the device, as evidenced by the appearance of its model in the window.
Press Unlock. You'll see a warning that all data will be deleted. Confirm. If the wait timer has expired and the account is tied correctly, the unlock process will begin, which will take from a few seconds to a couple of minutes. The progress bar will display the execution rate. Once completed, the phone will automatically reboot, and you will see the Unlocked inscription on the start screen.
⚠️ Note: During the unlocking process, it is strictly forbidden to turn off the cable. USB Or interrupt the program, which can lead to the resolution of the loader partitions and turn the phone into a brick".
Typical data entry errors and their solution
Even with a clear follow-up, users often encounter errors, one of the most common is the Error 10009 or the message that "Account isn't bound to this device." This means that you try to unlock your phone using an account that wasn't tied to the developer menu on that particular device, or that there hasn't been enough time since the link.
Another common problem is network error or connection timeout. Xiaomi servers may not be available from your region, in which case it helps to change the DNS on your computer (for example, 8.8.8.8), use mobile Internet instead of Wi-Fi or run the program in compatibility mode.
- 🚫 Couldn't Verify Device Error - Try Another USB-port (preferably) USB 2.0) and the original cable.
- ⏱️ Timer is not coming – make sure the phone is installed SIM-card of the same operator to which the account is registered and there is Internet access.
- 🔄 The anchor cycle -- if you untied your account and retired it, the timer resets. You have to wait again.
If the program says "Unlock time expired", it does not mean that the opportunity is lost. This message often appears if too much time has passed since the application was submitted (more than 30 days) without trying to unlock, in which case the procedure for linking the account in the developer menu should be repeated again and wait for a new deadline.
💡
Use the original. USB-Cheap charging cables often don't have the necessary contacts to transmit data, leading to persistent connection errors in the Mi Unlock Tool.
Impact of Unblocking on Warranty and Security
Unlocking a bootloader is an action that changes the security status of your device. After this procedure, some secure features such as Google Pay (now Google Wallet) and some banking applications stop working, as they change the integrity of the system. Although there are methods of bypassing (Magisk, root hiding modules), this requires additional technical knowledge.
As for the guarantee, Xiaomi formally allows the bootloader to be unlocked through the official tool. However, if the device fails during the manipulation of the software (installing custom recoveries, firmware), the service center can refuse free repairs, citing a violation of the software.
Data security is also reduced. With the bootloader unlocked, an attacker, having gained physical access to your phone turned off, could theoretically try to read data, although modern Android encryption methods make this extremely difficult.
💡
Unlocking the bootloader gives you complete freedom over the system, but it reduces security and can make it harder to use banking applications.
