📶 How to Repair IMEI (MediaTek Devices)

⚠️ IMEI restoration is only legal if restoring your original IMEI printed on the box/SIM tray.

Since POCO X6 Neo is a MediaTek device, use Maui META Tool or Modem META Tool to restore IMEI.

🛠 Restore IMEI Using Maui META (or Modem META)

Tools Needed:

• ✅ Maui META Tool
• ✅ Valid IMEI number (from SIM tray)
• ✅ Database file (DB) from your firmware (usually MDDB and APDB files)

---

Step-by-Step:

1. Install MediaTek USB Drivers
2. Launch Maui META Tool (run as admin)
3. Choose “IMEI Download” mode
4. Turn off the phone
5. Connect it via USB — Maui META will detect it when it boots into META mode
6. Load the correct DB files from the firmware
7. Enter the original IMEI1 and IMEI2
8. Click Write
9. Reboot the phone and dial *#06# to verify

🔐 Flashing Tips

• Use only Fastboot ROM (.tgz) — Recovery ZIP won’t work in Mi Flash
• Never lock bootloader unless flashing untouched stock firmware
• Keep battery charged to 50%+
• Always back up NVRAM/QCN before flashing (if possible)
• Codename: POCO X6 Neo 5G = gold
