As I see often people having problems after flashing roms, I noticed that they always forgot one important thing to backup.
So I decide to write this article about the importants of the EFS as it is your lifeline of your phone.

Maybe you already have heard of the EFS partition, if not then keep on reading.

The EFS is a partition where the most important device infromation like Wi-Fi address, Bluetooth MAC address, IMEI address, etc is stored.
Without this data, you won’t be able to use your phone anymore and it's completely bricked.
So It’s extremely important to keep a local copy of your EFS partition as when the EFS is damaged then your phone has become useless and can only be restored with your personal EFS file.
You can't use an EFS file from somebody else as the file is your personal acces code to your hardware.

Hopefully you will never have to restore your EFS partition.
However, it’s never a bad idea to make a backup copy, especially if you flash allot of roms like I do.
