After I have showed you how to backup and restore the Samsung Galaxy S3 EFS by using the one click method, today I will teach you another way for performing the same operation. This time, the step by step guide will be suitable for any Android based Samsung device, as you will use an app provided by those of xda-developers that can be installed on any Samsung handsets. In this way backing up the EFS folder will an easy task to complete, meaning that you can safely install custom ROMs and recovery images on your smartphones and tablets without being worried whether or not you will have network access afterwards.

The EFS folder contains important info about your phone, as the IMEI number of the device is being located on the same. Furthermore, each time you decide to update your Android based Samsung handset with a custom ROM, or beta firmware, the EFS might get wiped out. When this happens, you will not be able to have the network connection enabled, meaning that you can no longer use your smartphone. Therefore, for avoiding these unpleasant situations, it is recommended to first backup the EFS along with all the other data stored on your device. A backup is always well-received, so don’t hesitate and perform the same before changing or applying something on your gadget.

Now, as mentioned above, for being able to backup the EFS from any Samsung device, you will have to download, install and use a dedicated app, which is named simply, EFS Pro. But, for being able to use the EFS Pro tool, you need to have a rooted smartphone (the Android platform should be included of course); so, before heading to the download link from below, just gain root access over your phone’s internal system. Be aware though, as by rooting, the warranty will get void; you can restore the warranty by downgrading to the stock ROM or by updating to an official software released by Samsung and suitable with your device. Also, if you had lost the EFS and you cannot restore it, you should perform the same operations mentioned above (downgrading and so on) and you will be able to restore the EFS back to your phone.

In order to succeed with this operation, you will have to use a Windows powered computer (XP, Vista, 7) your Samsung device and its USB cord. Again, remember that the handset must be rooted. On the computer Microsoft .NET Framework 4.0 must be installed, or else the EFS Pro app will not work. Once you download the file, just unzip it and then install it on your PC. Next, you have to take your device and connect it to your PC. You can backup the EFS folder by running the EFS Pro app and by following the prompts. For more aspects, details and for the features list of the tool, you should take a look here (this is also the download link for the EFS Pro app).

So, that was all, you now know how to backup EFS from any Android based Samsung device. Remember that there are more methods available for performing this operation, though the present one might be the easiest one as you only have to download and install a program on your computer. Anyway, do tell us how the method worked for you and share the related issues or problems with us and with other users by using the comments area from below.
