[ATTENTION] Before every Modding operation save your EFS folder

Before every Modding operation with Odin or with Kies (update firmware) or debrand your Galaxy Note ecc. is better:

Root your phone and solve the EFS problem. The EFS folder is very important for the legality of your Galaxy and for your IMEI code.....copy your folder on desktop PC and in the external SD.
Root explorer is the application that help you in this operation.
The EFS folder is in the root of the galaxy system inside the SDcard...copy and paste the folder with MOUNT/RW MOUNT/MO

Please edit the guide, it isnt correct.
Backupping with rootexplorer does not copy the permissions, if I get time I will write a nice guide and MAYBE an app for it

[andromeda1968]

Yes now I have saved my EFS folder...

...CWM manager too

On the phone..

If you have root, do this from Android Terminal.

su
mkdir /sdcard/efs_backup
tar zcvf /sdcard/efs_backup/efs-backup_SGN.tar.gz /efs

I am recommending to copy this file also on external sd card, just to be safe.
This method will also copy the file permissions.

The command line doesn't work, it just says file not found for me.

There are quite a few apps out there that have a provision for saving your EFS folder.

I use Nitrality https://market.android.com/details?id=com.nfye.insanity.toolbox&feature

But the important question is why it is important ???? what could happen? i count my self as noob on android. i have an galaxy tab 7" and moded it with odin lots of times but never backed up my efs folder. also if i backup my efs folder how can i realize that i need to restore that ?

 

[stylobic]

i wanted to save but it's required to install busybox and i don't know how to do...
sorry but i come from IOS, i'm new on android...

i have root explorer installed, can i do just a copy of the EFS folder then save it ?

 

[andromeda1968]

EFS folder include IMEI codec number for your phone.
without IMEI or with corrupt IMEI is not legal....and you cannot sell in this way your Galaxy

 

[stylobic]

Then I guess I just have to save this EFS folder with root explorer ? no need special software to do it ?

 

[PolishDude]

so do I just literally copy the whole efs folder with root explorer and save it on my sd card, no more then that?

Or you could use this tool from Hellcat, ktool:

its pretty easy to use, you can install it from GooglePlay.

There's a small guide here on more ways to backup your efs folder, including ktool in the link bellow:
