For users of the 4G model with the 4GB/64GB configuration, issues like "No Service," "Invalid IMEI," or "Null Baseband" often require specific software repairs involving QCN and EFS files. These files are the "communication brain" of your device, handling network calibration and identity. Understanding the Essential Files
Re-flash official stock firmware from Xiaomi’s site or use MiFlash to restore modem files bundled with official ROMs.
Seek authorized service centers for board-level repair or IMEI restoration.
If you lost IMEI after repair: request the service center to restore original IMEI; do not use someone else’s QCN.
- QCN/XQCN and EFS files contain IMEI and radio calibration data. Restoring or modifying them can brick your modem or violate carrier/device warranty and local laws. Proceed only if you own the device and understand the risks. I will not provide copyrighted paid files or facilitate theft of IMEI/registration data.
