How to Backup and Restore IMEI in Android

The rooted Android phone allows us to do a lot of customizations including custom ROM. However, there is a possibility to lose IMEI numbers while flashing or updating ROM in Android devices.

If you lost your IMEI number during those processes, then your phone loses the ability to make and receive a call. To avoid this issue, you need to take a backup of the IMEI numbers.

Backup and Restore IMEI on Android

Let’s see a quick overview of IMEI number. IMEI stands for International Mobile station Equipment Identity. It is a unique identity number assigned to each mobile device.

To check the IMEI numbers of your mobile, just type *#06# in the mobile dial pad. It will show your device IMEI numbers. I recommend you to take a Nandroid backup before making any changes. Let’s get started.
