No, not the same, if need restore efs saved via root explorer, after this you mast back to all files permissions and owners, and this is a long and tedious process

Then in order to keep a copy on the phone (2 backups are better than one), would it be the same to run a

cp-p

in a terminal on the phone ?

What is EFS, Why it is necessary to backup

Click below to find answer

Backup/Restore EFS data of Samsung GN2, to Fix IMEI and SIM not detecting issues

What the hell is this EFS ?
EFS partition is actually a internal place in our android device such as android phone which contains some important and some basic info related to our device identity like Wi-Fi address, Bluetooth MAC address and the very main IMEI address (nv_data.bin).

Now if this EFS partition accidently corrupted then your phone’s IMEI no. will erased and you can not make voice call further. This kind of damage is often not accepted by the service center of your respected handset’s company.

Why should I backup EFS data ?
As said above if any case you corrupt EFS then EFS backup can be savior for you.
So it is very necessary to make a backup of this EFS partition just now to avoid such type of future troubles.

Now the question is “how to make a backup of EFS partition”.

There are three methods to make a backup of this EFS partition.

1st : OP is best tool to make backup/restore of EFS for Note2 Thanx to as i9100.

2nd EFS folder backup using root explorer
Just copy the whole EFS folder via root explorer to your SD card or anywhere in your PC. But according users criteria this method is not be good in EFS restore.



Using of a backup/Restore tool mentioned in OP will backup your whole EFS partition including read / write permission that makes your phone compatible for this task.

I guess your efs didn't backup also did they? And did it root?
There was an app called ktool in market that backs up and supposedly restore efs, but it doesn't support the note 2 and not sure how well it would work :/

i was able to get the efs to push to the phone but the IMEI number didn't repopulate...it rooted but lost IMEI as soon as it did...i think the root process only supports international versions and might have flashed something that my phone didn't like...i tried using kies to restore the phone but it doesn't recognize the serial number so i am screwed there as well

i unrooted using the same tool i used to root but still no signal and it still says modified in the status....so it looks like im going to have to wait for an odin of the stock image and then try and take it back...hopefully it shouldn't be modified anymore after that
