Samsung backup and restore EFS with ease using the Samsung Tool App. If you own a Samsung Galaxy device, you may be familiar with the EFS backup process when updating or installing a new firmware or custom ROM. EFS, short for Encrypting File System, is a partition that stores critical radio data and information on your device. It is essential to back up this partition before modifying your Galaxy device’s system due to its extremely sensitive nature, which may render your device’s radio dysfunctional and cause a loss of connectivity.
Incorrect or unsuitable firmware can damage the current EFS partition causing the radio issue, which results in the device’s IMEI being null. This EFS problem is more prone to occur when downgrading a Samsung Galaxy device. Therefore, backing up EFS data is crucial to saving your device from this issue. Although there are several methods available online to backup EFS on different devices, these methods vary between devices. We have previously covered some ways to backup EFS, but a simpler method was still necessary.
While browsing the XDA-developers forum, I stumbled upon the Samsung Tool App created by XDA Recognized Contributor ricky310711. This app is a lightweight and user-friendly tool that enables you to backup and restore EFS data on any Samsung Galaxy Device, regardless of its model number or firmware. The only requirements are that your device must be rooted and have a BusyBox installed. In addition to EFS Backup and restore options, the developer has also included bonus features such as reboot options. This app can be installed like any other APK. Let us proceed and explore how to use this application to backup and restore the EFS partition.
