How to fix DFH Default Error in Airtel

The “DFH Default Error” is a common issue on Android smartphones, especially with AIRTEL SIM cards.

Here are some steps you can try to resolve it:

  1. Restart Your Phone: Sometimes a simple restart can fix the error. Turn off your phone, wait a few seconds, and then turn it back on.
  2. Change MTK IMEI with USB Cable:
    • Put the battery in your phone and power it on.
    • Connect the USB cable.
    • Select “com” (communication port).
    • Install the driver from the MasterTool driver folder (usually located at C:\Program Files\MasterBox\Driver).
    • Use the IMEI option.
    • If IMEI is not switching on, disconnect the phone from MasterTool, minimize the window, select the com port, choose the driver from C:\Program Files\MasterBox\Driver\MediaTek, maximize the window, and click on IMEI at meta.
  3. Replace SIM Card: Insert your SIM card into another working phone. If the error occurs there as well, contact your service provider for a SIM card replacement.
  4. Reset Network Settings: This option resets all your network settings to factory defaults. It can be helpful if the error is caused by incorrect configurations. Be aware that this will also erase your saved Wi-Fi passwords, so make sure you have them handy before proceeding. (Note: The specific steps to reset network settings may vary depending on your phone model. Consult your phone’s user manual for instructions.)

Remember to follow these steps carefully, and hopefully, you’ll resolve the issue!
