Download Xiaomi QCN Files Collection All Models Free – Tested File
Xiaomi smartphones are renowned for their unbeatable value, robust performance, and innovative features. But like any smartphone, they’re not immune to technical issues—especially network-related ones like invalid IMEI, no service, or baseband unknown errors. Fortunately, if you’re using a Xiaomi device powered by a Qualcomm chipset, you can fix these problems using Xiaomi QCN files.
In this post, you’ll get access to the complete Xiaomi QCN Files Collection for all models—100% tested and free to download. We’ll also walk you through how to rebuild and write QCN files using tools like QCN Rebuilder and QPST, ensuring a quick and effective solution to IMEI and network problems.
What is a Xiaomi QCN File?
QCN stands for Qualcomm Calibration Network. It is a backup configuration file that stores essential radio calibration data like IMEI, RF NV items, and network configurations.
When your Xiaomi phone loses IMEI or shows “Baseband Unknown,” it’s usually due to a corrupted EFS partition or network calibration file. Flashing the appropriate QCN file can restore your phone’s IMEI and fix connectivity issues such as:
- No signal or no service
- Emergency calls only
- Invalid or null IMEI
- Corrupted baseband firmware
