EFS plays an essential role, specially when you’re playing with your device beyond the boundaries. You must have read this important point while flashing custom ROMs / custom recoveries or rooting your Android device “Make sure that you backup your EFS”, ever wondered what does it mean and why is it important? Well, if you are not familiar with EFS, let’s first have a brief introduction of EFS.
EFS stands for Encrypted File System. In Android devices the baseband information (IMEI) is stored in the form of EFS data, whenever you flash different firmwares there are chances that your phone’s baseband will get effected… So it is always safer to have backed up your EFS before you flash any file in your Android device. This is way too much important, specially when you buy a new phone, the very first thing you should do is to backup your EFS. In case of messing up your EFS will result in bad IMEI, it will either give you a generic IMEI or null. You can understand now what it will do, that means no signals on your device and no network at all. The only way to bring your phone back to the life of signals is flashing the backed up EFS.
Let’s get back to the topic. Our friend Dr. Ketan Hindocha, XDA-Recognized Contributor has developed an awesome app that allows you to backup your EFS in just one click on Samsung Galaxy Note 2 GT-N7100 & Samsung Galaxy Note 3 SM-N900.
