I've looked and searched and asked in a question form but still haven't found an answer. If you look at KTool app on market it says its in v1.56-beta1 *experimental* special support fort at&t s3 sgh-i747. My question is does the support work for backing up your imei/efs or is it just for flashing/dumping kernels and if so has anyone tried it does it work? Any help would be appreciated thanks.

I ran the KTool and it shows a back up as tar and a image i guess it works not sure???

I have it installed but i don't think it backs it up properly as i get a "nv_data.bin not found in backup". Andromizer is another app and i think it might work better. I also have it backed up these two other ways:

I've backed it up with these two methods as well, just seeing if there was an easier way. I thought KTool didn't work at first either then i ran the check and it found them so i went to root explorer and found the 2 files so i guess it worked if i lose my imei I'll try to restore with it first. I'll have to try andromizer haven't seen it before.

So I made a backup of my Aokp rom with a long times worth of tweaks and settings, with online nandroid. I flashed another rom and hated it, so I went to go restore my backup and it was nowhere to be found in CWM. Does anyone have any idea where it went? I couldn't find it in the backup folder and onandroid didn't make a folder in my SD

check the blobs folder
Don't seem to have one. I ran a search in my file manager and it didn't find anything. Would it be a sub folder in one of the other ones on the root of the SD?

i stopped using cwm a while bac,k use twrp now much better imho. it should be in the internal sd card under cwm-backup-blobs.
Can you post the log file at /data/local/tmp/onandroid.log
Did you save the backup to the internal SD and accidentally wipe it while flashing the new ROM you didn't "care" for? Hate is such a strong word especially here..it comes down to user preference..no ROM.is a bad ROM really..its just what you want to get out of it.
One more reason for me to not use the online nandroids. Never liked the sound of if when it came out. Too many things can go wrong.

I just rooted my phone and as I'm typing this I have the titanium backup running and well..backing up everything on my phone. Now I want to double check with the EFS file. I know that it is really important, especially before I start to flash a custom rom on my phone. So what I'm getting at is where in the world do I find this file and how do I back it up? Like I said all I'm wanting to do is double check this to make sure that it is done properly...any help is greatly appreciated!
Please make sure you are using the search feature. I found the below link within a few seconds.
EFS hold specific information about your phone such as the IMEI, IMSI, Data Settings, etc...
This is also known as an "NV Backup"

Ok so I have downloaded Andromizer and there are quite a few options on there backing up this and backing up that... from this thread that I created its about backing up the EFS folder, that is my main concern. I ran the backup, and it completed within seconds. What I'm getting at is...is that it? Is this all I need to backup or do I need to backup any other information pertinent to being "stock". I just want to make sure everything is perfect before I start flashing a custom rom or messing with kernels. Like I said before, any information is greatly appreciated. I'm open to learning about all of this.

Really besides EFS the only thing you need to do is make a nandroid of your current stock ROM.
After that, get to choosing your first ROM =)

This may seem a little redundant but did the Andromizer app get everything you mentioned before? You had mentioned something about the IMSI and a few other things...did that EFS backup include everything you mentioned? I'm assuming that all of those codes (if that's what they are...) are also important?
I apologize for all of the questions.... this is a learning experience for me lol

I'm not familiar with that app, but all of that data is included in the EFS folder. as long as it backed up the contents of that folder you'll be fine.

So the only thing I had to do to backup was this:
To make a backup:
Open Software Download from the Start Clients menu.
Click on the Backup tab.
Make sure your phone is listed under port.
Select the location you want to save your backup.
Click Start and wait for it to finish.
You should now have a QCN file of your NV.
Save the file in a safe place.

I remember my noob days. Believe it or not, it is really this easy on most Samsung devices. Don't nuke it out. As long as you followed the thread thoroughly and did what was instructed you are fine.
I encourage you to do a lot of reading and do not let yourself get panicked over things. Remember...as long as your phone can turn on, you are safe. As long as you read thoroughly and follow instructions, you will be fine. And regardless how confident you are in your skills after some time, remember to follow instructions anyway. Overconfidence will cause you more problems than being a noob who is willing to read.

Enjoy. Since its your first time avoid anything based on Verizon gs3 builds or sprint. Those can be a bit buggy and most new rooters don't want to deal with that...I know I didn't. Try custom and stock based and don't be influenced... Flash what you like and enjoy the good work done here

Ok so I followed the basic steps to create a backup of my qcn and produced a ~250kb file... not sure if this is adequate (size seems small?) but my phone seems to still be working fine so I guess ill share this experience and hope everone can expand or follow my lead to create a safe and secure thread to back up efs/modem/nv/imei
This OP will be updated as processes and verification of reliability stabilize.. not sure if there is already a thread for this but once I can confirm the process I used is adequate than proper thanks will be given and links will be provided....
Still need to confirm each and every step I used is accurate for backing up and restoring EFS/NV/Modem/imei so please be patient as this thread expands to hopefully prepare everyone to not fear the possible borked or mis-flash... I ultimately hope this thread can help everyone prepare a back up of their original stock files so there is no more mistakes without proper backups... if you have backed up any of these files and had success restoring than please feel free to share your solutions

You should also use the Androidmizer app to back up the EFS partition. The size with that app the EFS Backup comes out to be like 20mb or so. Look in the Themes and Apps section.

Does anyone have a tmobile qcn? I lost my aws band and so I followed the instructions on getting an ATT Note2 on TMobile but it just does not seek to have the same reception as before.
Ok, so I just had a little scare when I restored a backup and my imei and data were gone. Somehow pulling the battery and rebooting the phone brought it back but now I want to backup my imei. Could anybody provide me with a reliable and updated method on doing so? It seems that everything I find is over a year old and I'm not sure I trust using them.

Download and run Terminal Emulator.
Entter the following
su
reboot nvbackup
That's it! You now have an on device backup and you won't have to redo it. If you need to restore, enter this
su
reboot nvrestore
Alternatively, there are two apps I know of that do this for you. Andromizer is one and is in the store. The other is nv backup/restore. I have a copy but don't remember where I got it or who to give credit to.

Not that I am aware of unfortunately.
When it rebooted you shouldve seen blue text flash on the screen. Kind of like when you boot into recovery, but different.
I do plan to try and hunt this down at some point, I've just got too many other things I need to finish before I go digging in somewhere else!
As long as you saw what I described, I'd be confident that it worked. And if you find later that it didn't, you can still pm me for the old-style fix!

No, it gets saved to a different area of the phone, on a different partition. Recovery and Odin flashes won't touch it so it'll remain indefinitely, that's how I understand it anyway.

The root folder efs? I believe it is different from Samsung. Searching for mk9efs from system root led me here - /dev/block/platform/msm_sdcc.1/by-name/ . Searching for efs from the system root doesn't supply much, the location I just posted and a few other folders like efs-bridge. Now I may be wrong on this, @engine95 knows more than I, but I am under the impression that our efs are on 3 separate partitions and may not be accessible from a root file explorer. I don't think we have a root efs "folder". Again, I am NOT 100% on this and could be completely wrong.......

I'm not quite sure what he's asking.
The EFS backup with TWRP creates an "EFS folder with 3 files in it.
And if I remember right... @HPTesla is right. EFS is in 3 partitions. One of them is actually empty, but is still needed.
You can see the mk9efs files in the folder but that's it. Im guessing FreeGee and TWRP are basically just taking a picture of the partitions.
So to the OP, are you trying to make sure the files are there? Or are you trying to access the files in there?

? You should be able to do it from within TWRP. It depends on the version of TWRP you are using, 2.5.0.0 has been the most stable for this phone in my experience. It's an option in my backup and restore that I can check/uncheck. However, TWRP 2.6.3.0+ is needed to flash almost all 4.4 based roms and the options are different.

If you are still using the same TWRP version you used to make the backup but switched to an AOSP based rom it appears as if the backup disappeared. The backup is located in /data/media/TWRP but TWRP will look in /data/media/0/TWRP. You can copy the old backup to the 0/TWRP folder and reboot recovery.
If you are using a different version of TWRP than the one you used to make the backup, your backup may also not show up. You should use the version you used to make the back up to restore it back. I hope this helps.
