Efs Backup Without Root: A Comprehensive Guide

Introduction

If you’re an Android user, you’re probably familiar with the concept of EFS backup. EFS stands for “Encrypting File System,” and it’s a feature in some Android devices that stores important data like IMEI numbers and network information. However, backing up your EFS partition can be quite tricky, especially if you don’t have root access. In this article, we’ll show you how to do an EFS backup without root.

Why Backup Your EFS Partition?

Your EFS partition contains a lot of important data that you don’t want to lose. For example, your IMEI number is stored in this partition, and if it gets corrupted or lost, your phone may not be able to connect to your carrier’s network. Additionally, some apps rely on data stored in the EFS partition, so if it gets corrupted, those apps may not work properly.

Method 1: Using ADB

One way to backup your EFS partition without root is by using ADB (Android Debug Bridge). Here’s how to do it:

1. Connect your Android device to your computer using a USB cable.
2. Open a command prompt or terminal window on your computer.
3. Type “adb devices” to make sure your device is recognized by ADB.
4. Type “adb shell” to enter the shell on your device.
5. Type “su” to gain root access (if you have it).
6. Type “dd if=/dev/block/bootdevice/by-name/modemst1 of=/sdcard/modemst1.img” to create a backup of your modemst1 partition.
7. Type “dd if=/dev/block/bootdevice/by-name/modemst2 of=/sdcard/modemst2.img” to create a backup of your modemst2 partition.
8. Type “exit” to exit the shell.
9. Type “adb pull /sdcard/modemst1.img” to copy the modemst1 backup to your computer.
10. Type “adb pull /sdcard/modemst2.img” to copy the modemst2 backup to your computer.

Method 2: Using a Third-Party App

Another way to backup your EFS partition without root is by using a third-party app. One popular app for this is called “EFS Pro.” Here’s how to use it:

1. Download and install EFS Pro from the Google Play Store.
2. Open the app and grant it the necessary permissions.
3. Click on “Backup” and then select “EFS” from the list of options.
4. Wait for the app to create a backup of your EFS partition.
5. The backup will be saved to your device’s internal storage.

Conclusion

Backing up your EFS partition is important if you want to avoid losing important data or experiencing issues with your device. While it can be tricky to do an EFS backup without root, there are methods available that make it possible. By following the steps outlined in this article, you can ensure that your EFS partition is backed up and secure.
