Restore Your Lost IMEI Number for Android

Recover and restore IMEI number if lost on Android and fix null IMEI. Also, fix SIM network issues along with invalid IMEI.

If you lost your device IMEI number due to some changes and you are unable to connect to the SIM network then this post could make your day. Here we will learn to recover our lost or modified IMEI number on Android.

The Invalid IMEI is a common problem faced by most MediaTek devices including Xiaomi Redmi, Micromax, Oppo, Samsung, Vivo, HTC, Sony etc. The issue generally happens when you install a custom ROM, update your Android device or manually modify the IMEI.

The issue mostly occurs in Mediatek based Android smartphones. The problem causes the network to be unrecognised by the SIM card and the SIM will not show any signals or network.

Here I have come up with few methods to fix the problem of IMEI and get back your IMEI on your device.

Method 1. Assign IMEI Number

⇒ Requirements

  1. Rooted Android Phone.
  2. You should know IMEI number of your device.

⇒ Get the IMEI Number

  • Dial *#06# in the dialer.
  • You Can also check for IMEI in About phone under Setting.
  • You can also find IMEI in Box or somewhere on the battery.

Download and Install MTK Engineering Mode App (Preferred) or Mobile Uncle tools.

Steps to Follow to Recover Lost IMEI

⇒ Root Access required.

Step. 1  In MTK Engineering Mode App select MTK settings.

Step. 2  Go to connectivity and select CDS information.

Step. 3  In CDS select Radio information.

Method 2. Install IMEI Backup

⇒ Requirements

  • IMEI number
  • Download Mobile MTK write Tool zip
  • Download Uncle Mobile Tool
  • PC

Steps to Follow to Get Back the IMEI

Step. 1  Open the MTK tool application file and First enter the command and hit enter.

Step. 2  Now Enter the IMEI number and hit enter.

Step. 3  Again enter the IMEI number and hit enter.

Step. 4  Create IMEI.bak file and copy it your device storage.

Step. 5  Open the mobile uncle tool, choose IMEI Backup & restore the .bak file

Step. 6  Once done reboot the device. You will see the network again.

Method 3. Use Device Codes and Commands

This method is preferred for Samsung devices but you can try on other manufactured smartphones.

  • In the dialer, type- *#197328640# or *#*#197328640#*#*
  • In Command Mode, select the option “Common”.
  • (Imp) Without leaving the Command screen, press the Menu key.
  • Select Key input and turn your FTM OFF
  • After a minute remove the device battery and SIM. Place the battery back but not the SIM card. Turn on the device.
  • When the phone is booted, enter the command mode again dial – *#197328640#
  • Select the Debug Screen followed by control.
  • Afterwards, click “RRC (HSDPA)
  • To Fix not registered on the network, click RRC revision
  • Choose HSDPA only
  • Reboot your phone and then insert the SIM card to dial *#06# to see if the IMEI number is restored.

Note & Conclusion: Do not make any unnecessary changes in MTK App it is a very sensitive tool.

    I had my original IMEI numbers (phone was only a day old) for my Doogee X10 but lost them on the phone after flashing the ROM. I tried everything, even to root it but couldn’t get anything to work. Then I found on some page the following;

    Just type *#4634# in the phone dialler and enter the IMEI numbers and tell it to save. Reboot the phone and all is restored.
