How to repair IMEI Xiaomi Mi5: 3 proven methods + error-dissection

Why is it missing? IMEI Xiaomi Mi5 and what the danger is.

Xiaomi Smartphone Mi5 (The codename Gemini is still popular with enthusiasts due to the powerful hardware based on the Snapdragon 820 and the ability to customize. However, after a failed firmware, reset to factory settings or experimenting with the modem, many users face loss of the device. IMEI — a unique device identifier on cellular networks. IMEI phone loses its ability:

✔ Call and receive calls (Error "Only Emergency Calls»)

• 🔹 Check that you downloaded the backup for the correct version Mi5 (For example, Gemini Global does not work with a file from Gemini China).
• 🔹 If fastboot makes a mistake FAILED (remote: unknown command, update Qualcomm drivers via QFil Tool.

💡

If after the firmware nvram phone stopped seeing SIM-maps, perform network reset in settings: Settings → SIM-maps and mobile networks → Resetting network settings.

Method 3: Use of QFil Tool (for bricks)

If Xiaomi Mi5 not included or stuck on the logo (brick), restore IMEI Qualcomm Flash Image Loader (QFil) is a low-end utility that can resuscitate a phone even with damaged firmware.

What you need:

• 🔄 Avoid fastboot erase commands for nvram, nvdata, modem partitions.
• 📱 Do not install firmware from other models (for example, from Mi5s on Mi5).
• 🔧 Before experimenting with a modem (for example, to improve the signal), save the original files.
• 🛡️ Use only proven custom firmware (e.g. LineageOS or Pixel Experience with support) Mi5).
