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.
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.
Backup IMEI [Rooted MTK Android Device Only]
- Download and install the app.
- Grant root access permissions to the app.
- Click on “IMEI Backup Restore (MTK)” option.
- Now, you can see 4 options. The first 2 options are to backup IMEI and the last 2 options are to restore IMEI.
1. Backup IMEI to SDCARD(MTK) – used to backup to your internal storage.
2. Backup IMEI to SDCARD2(MTK) – used to backup to your SD card.
- You can choose the option as per your wish. In this instance, I’m choosing the second option.
- Tap “Ok” for the confirmation message.
That’s it. Now, you can see the backup file on the SD card. I recommend you to keep a copy of this backup file to the cloud (Google Drive, Dropbox) or on the Laptop.
In case your IMEI numbers are lost, then you can use IMEI backup to restore.
- If your backup is on the internal phone storage, use the “Restore IMEI from SDCARD (MTK)” option.
- If your backup is on the SD card, use the “Restore IMEI from SDCARD2 (MTK)” option.
