IMEI Null on Tecno and Infinix After Flashing

When Tecno or Infinix smartphones show IMEI as null (000000000000000) after firmware flashing, it means the NVRAM partition that stores the IMEI was erased during the flash operation. This causes the device to have no cellular service, no SIM detection, and show "Emergency Calls Only" or "No Service" even with a working SIM card inserted.

This is one of the most common post-repair issues in mobile shops handling Tecno and Infinix MTK devices in 2026. Fortunately it is fully fixable.

Confirm IMEI is Null

  1. Dial *#06# on the device
  2. If IMEI shows 000000000000000 → IMEI is null
  3. If no IMEI prompt appears at all → IMEI and modem not initialized
  4. Check Settings → About Phone → IMEI — shows null or empty

Find the Original IMEI

Before writing the IMEI, find the correct original IMEI:

  • Check the original device box — barcode sticker shows IMEI1 and IMEI2
  • Check under the back cover or near the SIM slot
  • Check the purchase receipt
  • Contact the original seller with proof of purchase
⚠️ Critical: Only write the IMEI that originally came with the device. Writing a different device IMEI is illegal in most countries. Always use the IMEI from the original box sticker.

Fix Method 1 — MauiMeta Tool (MTK META Mode)

  1. Install MTK USB VCOM Driver on PC
  2. Download MauiMeta Tool (available on this website)
  3. Open MauiMeta and set port to MTK VCOM port number

  10. Click Write IMEI
  11. Success message appears — restart device
  12. Dial *#06# to verify IMEI restored

Fix Method 2 — SP Flash Tool NV Restore

If you created an NV backup before flashing:

  1. Open SP Flash Tool
  2. Go to Read Back tab
  3. Click Add and select NVRAM from the backup
  4. Click Read Back button while device is in BROM mode
  5. NV data restores including original IMEI

Fix Method 3 — Flash NV Protected Firmware

To prevent IMEI loss in future — flash firmware with NVRAM protected:

  1. Open scatter file in text editor
  2. Find NVRAM partition — change is_download to false
  3. Flash with this modified scatter — NVRAM not touched
  4. IMEI preserved throughout firmware operation
