The process involves using specialized tools to restore the IMEI data and repair the NV data corruption, which can cause issues with mobile network connectivity.

Here’s a guide on how to fix dual IMEI issues and NV data corruption on these devices:

Requirements:

  1. Windows PC or Laptop
  2. A USB Cable to connect your phone to the PC
  3. MI Flash Tool or QFIL Tool (Qualcomm Flash Image Loader)
  4. MTK USB Driver for Redmi 9A/Redmi 9C or Qualcomm USB Driver for POCO C3
  5. IMEI Repair File (You may need to get this from a trusted source)
  6. NV Data Backup (If available from your phone)
  7. Internet Connection (To download necessary drivers and tools)

Step-by-Step Guide to Fix Dual IMEI & NV Data Corruption

Step 1: Install USB Drivers

  • First, you need to install the appropriate USB drivers on your PC to ensure that the phone is recognized when connected to the computer.
  • For Redmi 9A or Redmi 9C (which use MediaTek processors), install MTK USB Driver.
  • For POCO C3 (which uses Qualcomm chipset), install Qualcomm USB Driver.

Step 2: Backup Your NV Data

  • If possible, backup the NV data of your device using any data backup tools available for your phone model. This will help prevent data loss during the fixing process.
  • If you’re unable to backup NV data, you can proceed, but note that some data may be lost during the repair process.

Step 3: Download Necessary Tools

  • MI Flash Tool (for MediaTek devices like Redmi 9A/Redmi 9C).
  • QFIL Tool (for Qualcomm-based devices like POCO C3).
  • You’ll also need the IMEI Repair Tool (this may vary based on the device model, so ensure you download the correct one).

Step 4: Enter Fastboot or EDL Mode

  • Redmi 9A/Redmi 9C:
    • Power off the device.
    • Press Volume Down + Power Button to enter Fastboot Mode.
  • POCO C3:
    • Power off the device.
    • Press and hold Volume Down + Power Button to enter EDL Mode.

Step 5: Flash Stock Firmware

  • For Redmi 9A and Redmi 9C (MTK-based):
    • Open MI Flash Tool on your PC and select the stock firmware for your device.
    • Click on Flash to begin the process.
    • Wait for the process to complete. This will fix software-related issues and might help restore the IMEI if it was corrupted due to firmware issues.
  • For POCO C3 (Qualcomm-based):
    • Open QFIL Tool and load the correct XML files for the device.
    • Click on Download to begin flashing.
    • Wait for the flashing process to complete. This will also reset the IMEI and NV data.

Step 6: IMEI Repair

  • Once the flashing is completed, the dual IMEI problem may be resolved. However, if the IMEI is still corrupted:
    • Use an IMEI Repair Tool like MTK Droid Tool or QCN Write Tool (for MediaTek or Qualcomm devices) to manually restore the IMEI.
    • Open the IMEI Repair Tool, select your device model, and write the correct IMEI numbers.
    • If you have the QCN file for your device, you can restore the QCN data that includes the correct IMEI and NV information.

Step 7: Reboot the Device

  • Once you have repaired the IMEI and NV data, reboot your device.
  • The device should now show the correct dual IMEI and the network should be functional without issues.

Step 8: Test Network Connectivity

  • After the fix, test the network connectivity by inserting a SIM card into the phone.
  • Check if both IMEI numbers are active and if the device is properly connecting to the network.

Additional Tips:

  1. IMEI Numbers: If you don’t have the original IMEI numbers, you can find them in the phone’s box or on the back of the device.
  2. NV Data Corruption: If the NV data is corrupted, it might cause problems with connectivity or network services. Always backup your data before performing such repairs.
  3. Permanent Fix: For a more permanent fix, it’s best to get your phone’s IMEI repaired by a professional technician if the above steps don’t work.

Conclusion:

By following these steps, you should be able to fix the dual IMEI issues and NV data corruption on your Redmi 9A, Redmi 9C, or POCO C3. This free solution involves using tools like MI Flash Tool, QFIL, and IMEI Repair tools to restore the device’s network functionality. Always make sure to follow the steps carefully, and if in doubt, consult a professional technician.
