I am not sure how many of you visiting this page are familiar with the presence and importance of the EFS thing that we are going to talk about today! Actually, I often hear people requesting to offer a solution of a problem that makes them unable to make a call, send a message, access the internet or any connectivity related thing. Imagine a mobile phone without a network connection at all and you’ll then realize how horrible it is! If EFS is so important a thing, it must be preserved so that you might be able to use all connectivity features of your device. This thing is found in all mobile devices which have an IMEI (International Mobile Equipment Identity) number assigned to it but the location and directory where it is stored might differ. On Samsung Galaxy devices, the IMEI and other connectivity data are stored in this particular folder that I have been mentioned several times so far.
Having read about the role of EFS on your Samsung Galaxy phone or tablet device, you must be a little more curious to know something more about it. EFS is a system directory that contains device specific essential information such as its IMEI, wireless device MAC address, baseband version, product code, system ID and NV data. In case the EFS directory is corrupted or lost, your phone or tablet is sure to lose its IMEI number and wireless and network connectivity.
Just download the firmware version you want from the second or third posts and extract the.tar or.tar.md5 file in the archive and save it somewhere 2. Reboot your phone to download mode.
You might ask how and why does the EFS data on your device might be lost or get corrupted? The answer is pretty simple and the reason might be a daring activity on your part.
Sometimes flashing a custom Kernel (as reported by some users) and in most cases installing a custom ROM is responsible for the EFS data loss. In this way, the EFS or IMEI loss is deeply related with what you do after rooting your Samsung Galaxy device. Keeping this thing in mind most of our ROM developers insert a script that automatically creates a backup of the EFS data on the external SD Card so that you might restore it back in case of loss or corruption. But it is certainly not wise to rely blindly on the wisdom of others. That is why, whenever we write installation tutorials for custom ROMs for Galaxy device, we warn users to backup EFS before indulging in any custom development activity. Sadly, most people come to know about the thing called “EFS” only when it is too late.
Once lost without being backed up, recovering it becomes very much like a wild goose chase. You might have heard or faced personally the issue when your device shows the inability to mount EFS: E: failed to mount / efs (invalid argument) If you get this message on your phone’s screen, believe me, you have got into a serious problem. Of course, there are ways to restore EFS data, but they are either not available for all devices online or they do not work at all. It has been well said that “prevention is better than cure” and this saying holds quite true in this case too.
Therefore, the first thing that one must do just after rooting and installing a custom recovery one’s device is to back up the EFS and the stock rooted firmware.
