The Xiaomi Redmi Note 7 remains one of the brandβs most popular smartphones, but many users are faced with the problem of blocking by IMEI, the so-called βblacklistβ, which occurs when a device is lost, stolen or incorrectly firmware. Unlike modern models, where the locking mechanisms are transparent, the Redmi Note 7 (codenamed lavender) has a nuanced verification and recovery process.
In this article, we will discuss where the blacklist on the Xiaomi Redmi Note 7 is physically and logically stored, how to check if the device is in the database of blocked IMEIs, and what to do if the phone is in this list, and pay special attention to official and informal methods of unlocking, as well as the risks associated with βgrayβ schemes.
Important: Information is relevant for MIUI 10β14 firmware and all Redmi Note 7/7 Pro modifications (including global and Chinese versions).If your device was purchased by hand or has signs of βgrayβ imports, we recommend that you immediately go to the section on the IMEI legality check.
What is the IMEI blacklist and why does the Redmi Note 7 get it?
The IMEI blacklist is a database in which carriers and manufacturers enter the identifiers of devices stolen, lost or blocked for other reasons. For the Xiaomi Redmi Note 7, there are two types of locks:
- π Operator lock β imposed by the mobile operator (for example, if you do not pay a loan on your phone or on a claim of theft) only works on the network of this operator.
- π« Manufacturer lock β activated by Xiaomi through activation servers MIUI. Blocks the phone completely, even after resetting to factory settings.
The Redmi Note 7 is more common in the second type, as it was widely distributed through unofficial channels.
- π± Buying a phone with your hands that was previously stolen or lost (the previous owner could report it to Xiaomi).
- π Failed firmware through Fastboot or EDL, where IMEI was dropped or replaced.
- π οΈ Repair with replacement of motherboard without re-registration IMEI at Xiaomi Service Center.
- π Use of the phone in a country where it has not been officially certified (e.g., the Chinese version in Europe).
β οΈ Note: If you bought a Redmi Note 7 off the hand at a suspiciously low price (below 70% of the market price), there is a high risk that the phone is already on the blacklist. IMEI before purchase through services such as IMEI.info or the official Xiaomi portal.
Manufacturer lock on Redmi Note 7 implemented through the activation servers MI Cloud. When the first setup after reset, the phone sends a request to the server Xiaomi with the data IMEI. If the ID is listed in the blacklist, the device is locked with the message "This device is locked" or "Couldn't verify device".
Where is the Redmi Note 7βs blacklist physically stored?
Unlike current models (e.g. Redmi Note 10), where the blacklist is synchronized in real time with the cloud, the Redmi Note 7 uses a hybrid system.
- The local firmware database is /system/etc/security/blacklist.xml (only available with root rights) and contains a list of IMEIs blocked at the MIUI level.
- NVRAM-partition β memory chip where the original is stored IMEI If this partition is damaged, the phone may lose its ID.
- Xiaomi servers are the central database from which the lock status is synchronized when activating or updating the firmware.
In practice, the user is only available to the third item - Xiaomi servers. Local file blacklist.xml can be viewed only through ADB or custom recovery, but editing it is useless: the next update to MIUI it will be overwritten from the server.
| Storage type | Location. | Can we change it? | Effects of change |
|---|---|---|---|
| Local MIUI file | /system/etc/security/blacklist.xml | Yeah (with root) | Resetting when updating firmware |
| NVRAM (IMEI) | Memory chip on the motherboard | Yes (via engineering menu) | Risk of damaging the modem |
| Xiaomi server | Cloud database | No (only official request) | Permanent lockdown |
If your Redmi Note 7 is locked, check if it is due to NVRAM damage first.

- Check the IMEI string. If it shows Null or 000000000000000000, the problem is in the hardware.
