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.

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.
