Introduction
Losing important data on your Samsung device can be frustrating, especially if you haven’t backed it up. One of the most critical pieces of data on your device is the EFS, which contains essential information such as your device’s IMEI, wireless MAC address, and other unique identifiers. In this article, we will discuss how to backup your EFS on Samsung devices.
What is EFS Backup?
The EFS (Encrypted File System) is a partition on your Samsung device that stores important information such as identification numbers, encryption keys, and other critical data. Backing up your EFS ensures that you can restore your device to its original state if anything goes wrong, such as a failed software update or accidental deletion of the EFS partition.
Why Should You Backup Your EFS?
The EFS partition is essential for your device’s proper functioning, so losing or corrupting it can cause serious problems. If you do not have a backup of your EFS, you may have to pay for costly repairs or a new device. Therefore, it is essential to backup your EFS regularly to avoid any potential issues.
How to Backup EFS on Samsung Devices
There are several methods to backup your EFS on Samsung devices. Here are some of the most common methods:
Method 1: Using Samsung’s Built-in Backup Feature

Method 2: Using TWRP Recovery
TWRP (Team Win Recovery Project) is a custom recovery that allows you to perform various system-level operations on your Samsung device, including backing up your EFS.

Connect your Samsung device to your computer using a USB cable. 2. Open a command prompt or terminal on your computer and enter the following command: adb shell su -c “dd if=/dev/block/platform/*/by-name/modemst1 of=/sdcard/modemst1.img” 3.
