Development of the might Galaxy Note 4 is greatly in runs now. There’s something new coming up every day to unleash the capabilities of the Galaxy Note 4. Since the device sports some seriously massive specifications, you won’t be able to refrain yourself from going out of the limitations and tweak your new beast at its best. Before you start flashing custom ROMs, mods, and make tweaks, there are several important things that you need to take care of, and EFS partition happens to be one of them.
Once messed the EFS partition without having the EFS backup, your device will become pretty much useless forever as you won’t be able to enjoy the phone capabilities of your phone and it will become a smart device only instead of a smartphone. Basically, the EFS partition, that stands for Encrypting File System, it includes all information of your device’s radio, base-band, Bluetooth MAC address, Wireless MAC addresses, product code, most importantly IMEI code, programming parameters and data provisioning parameters. Flashing a wrong file, downgrading your Galaxy Note 4, flashing a wrong bootloader or an invalid custom ROM, invalid kernel or any other such file will result in messing up your EFS partition. This will erase your IMEI number, instead of your device’s original IMEI number, a null or generic IMEI will appear and it will result in causing No Service issue, that won’t let your device detect your SIM card and phone will stop working.
Now that you’ve a good idea about the EFS partition, you may wonder how to handle this issue if it happens. The only solution is, restoring your EFS backup, but what if you haven’t even backed it up? Well, that’s the most important thing you should do if you’re a power user and you’re going to modify your device right away. To keep everything safe and sound, EFS backup should be kept atop.
