The situation where your Xiaomi suddenly gets blocked with a requirement to enter a Mi Account that you do not remember or create is familiar to many users, a phenomenon that is most common on devices bought with hands or brought from China, and means that the gadget is listed on the manufacturer’s servers blacklist.
Once in Blacklist, the smartphone becomes a brick with simple player functionality, as access to basic system functions will be limited. It is important to act consistently and carefully check the status IMEI pre-purchase.
In this article, we will look at all possible solutions, from official support requests to complex technical manipulations, how to check the device for theft, what codes to use for diagnosis and when to contact professionals. Full unlocking is possible only with a purchase check or a box with a unique activation code.
Reasons for the device to hit Blacklist
Mi-level locking is part of Find Device security to protect the owner’s data and keep the device safe from theft.When the phone is flagged as lost or stolen, it is automatically entered into Xiaomi’s server database. When you try to activate or reset the system checks IMEI-device code.
There are several scenarios in which your gadget may be on the blocked list: often users buy used equipment without knowing its status, the seller could simply forget to untie the account or deliberately hide the fact of blocking, and the problem is also relevant for devices imported from China, where strict registration rules are strict.
- 🚫 Theft or loss: The rightful owner filed a missing person’s claim and blocked the device remotely.
- 💸 Loan obligations: the phone was bought in installments and payments stopped coming in.
- 🔄 Previous owner sold phone but didn’t leave his Mi Account.
- 🇨🇳 Chinese version: global firmware on Chinese device may conflict with regional activation servers.
⚠️ Warning: If you bought a phone with your hands and it got locked, contact the seller.If this is not possible, self-unlocking without a check can be considered illegal.
Checking the blocking status through IMEI
Before you start taking action, you need to make sure that the problem lies in the server lock, not in the forgotten password. This uses a unique device identifier - IMEI. It can be found on the box, under the battery (if it is removable), or on the check.
The locked screen often displays a message saying “This device is locked to Mi Account.” To check the status, go to the dial menu (if access is open) and enter the code *#06#. The system will show the identification number that you will need to check with the databases.
Official and third-party resources are available for verification; Xiaomi’s official website allows you to check the status of warranty and binding, but full information about blocking is often hidden from ordinary users.
Where to find IMEI without turning on your phone
Checking through service databases allows you to know not only the status of the lock, but also the history of repairs or replacements, which is critical when buying used equipment «Lost/Stolen», Unlocking such a device legally is almost impossible without the involvement of the police or the original owner.
The official method of unlocking through Mi Cloud
The easiest and most legal way to remove a device from the blacklist is to use the Mi Cloud cloud service, which works if you know the username and password from the account to which the phone is linked, or if you have access to the mail to which it was registered.
You'll need a computer or other smartphone with Internet access. Go to i.mi.com and log in to your Mi Account. From the device management menu, find your locked gadget and select the unblock or unblock option.
☑️ Algorithms of actions through Mi Cloud
Once the command is completed, Xiaomi servers will receive a signal to remove the restrictions. The phone needs to be rebooted and connected to the Wi-Fi network. During the activation process, the system will request confirmation, and if the status is changed, access will be restored. It is important that at the time of reset, the phone is connected to the Internet to obtain current status.
If you bought a phone with your hands and the seller claims to have an account with you, ask them to remotely untie the device through their account, which you can do even if you're in another city, and then you can register a new Mi Account in your name.
Use of secret codes and engineering menus
In some cases, especially on older models or certain versions of MIUI firmware, special engineering codes help, allowing you to access hidden system settings where you can try to reset activation settings or change the region.
To enter the engineering menu, dial ##6484## or ##4636##. However, it should be understood that modern versions of Find Device security block the ability to reset through the menu if the phone is listed on the server blacklist, these methods more often work for resetting local screen passwords than server lock.
| Code. | Function | Effectiveness in blocking |
|---|---|---|
| *#06# | IMEI verification | High (for diagnosis) |
| ##6484## | CIT Menu (Tests) | Low. |
| ##4636## | Phone information | Medium |
| ##7780## | Resetting settings | Low (account required) |
Using reset codes like ##7780### will clear the data, but when turned on, the phone will again request the password from the Mi Account.This is standard security behavior. There is no "magic code" that will instantly remove the phone from the global blacklist without interacting with the server.
💡
Before any manipulation of the codes, back up important contacts and photos if you have access to the file system, as a reset can delete all data.
Technical Unlocking via ADB and Fastboot
For advanced users, there is a method of unlocking via a computer using USB debugging (ADB) and Fastboot mode. This method requires drivers, ADB utility and, in some cases, an authorized Mi Account with a high level of privileges.
The method is to try to flash the device or modify the system files responsible for checking activation. However, since MIUI 9 and above, Xiaomi has significantly increased protection. Now, to unlock the bootloader, you need to wait 168 hours (7 days) from the moment of attachment of the account.
adb devices
fastboot oem unlock
fastboot flash recovery recovery.imgThese commands cannot be executed without the bootloader unlocked. If the bootloader is locked, the phone will not accept the firmware commands. There are paid services that use vulnerabilities in older chipsets (such as Qualcomm EDL mode) to flash the phone around the checkout, but this requires special equipment (Test Point).
⚠️ Note: Using third-party utilities to reset your Mi Account (Bypass tools) can lead to complete inoperability of the device or fall into a perpetual reboot cycle (Bootloop).
Contacting the Service Center and Support
If the software methods do not work, the only guaranteed option is to contact an authorized Xiaomi service center, which requires you to provide proof that you are the legal owner of the device, which can be an original check, a purchase agreement or a box with a sticker that indicates IMEI.
The service center staff have access to internal databases and can send a request to the server to unblock the device, which can take days to weeks as the request passes security checks, and if the phone is internationally wanted, unlocking will be denied.
💡
Having a check or box with a matching IMEI is the only 100% way to legally unlock a stolen or lost phone through the service.
It's worth noting that service centers don't unlock phones that are bought in the grey or on the black market without documents, and if you don't have any ID, the chances of recovery are minimal, and in these cases, the device is often disassembled for parts.
Prevention and advice when buying
To avoid a blacklist problem, you need to be careful when buying Xiaomi equipment, especially used. Always check the device before transferring money. Turn on your phone, connect to Wi-Fi and try resetting to factory settings (Settings → Advanced → Reset).
If the phone asks for a password from an unknown account after the reset, you can't make a deal. Also check the IMEI on the manufacturer's website. Don't buy phones that are "locked up" for a specific carrier unless you plan to use the carrier's SIM card.
- ✅ Always demand a box and a check when buying used equipment.
- ✅ Check it out. IMEI Online services before payment.
- ✅ Make sure the seller is logged out of your Mi Account and Google account with you.
- ✅ Avoid buying phones with a cracked screen in the plume area - this could be a sign of artisanal repairs after theft.
Keeping these simple rules in mind will help you avoid buying a brick and save you nerves and money, and remember that the cheapness of a device is often due to hidden issues such as IMEI locking or stolen status.
