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"

I had no idea it was known as NV backup, I'm still new to all of this. Sorry about that mistake, regardless thanks for your help.

There are apps like andromizer and galaxy 2 unlock that will back them up for you and you can move them to you HD or ext SD card as well

Since I'm still getting used to all of this, is there some sort of guide I can use to make sure I'm doing it all properly? Or does the app do it all automatically?

Yes it is. Much better chance of restoring your imei if it gets all jacked up.

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

Unfortunately there's not that I know of, I always label nandroid as soon as I make them to keep from forgetting. If you do start renaming them, make sure there are no spaces in the name otherwise you will get an md5 mismatch error (assuming you are on cwm, TWRP does not have this problem)
You just have to rename your nandroid backups on your computer. It's in your sd folder when you connect your phone under clockworkmod. I have 3 backups, and I name them after the rom /theme that they are.

I am starting to do that, but like the ones from when I began flashing (about a month ago) I have like 5 nandroid right now. I think thats a bit excessive considering that I only used AOKP, Jugg and Stock. And thanks for the heads up about the md5 thingy. I don't rename them on my computer, I upload to box.net and add it in the description. That way I can keep my cluttered computer a bit cleaner. And I have 50GB so it doesn't really matter.
Use ROM Manager for backups as it gives you the option of naming the backup before hand. Personally I'm very specific on the names. I include the ROM, date, and other things like any mods or stuff like that

Make sure that you have unknown sources enabled in setting/security
Install the apk
Run the app
scroll down to 'Root device' and tap it.
Let it do its thing and if it doesn't automatically reboot after I would say 8 to 10 minutes, reboot the phone.
You should be rooted.

It's nice to see people actually help noobs out. It all seems so easy once you understand how it works but it can be overwhelming and a little verbose. Especially, the instructions for the Roms I started with and hoping inside that you don't brick your phone on the first try.
I do thank you all for the help. I did somewhat mess it up but recovered and flashed rooted ics and agat recovery. So thanks again. Can't wait to start flashing. By the way I was in recovery to create nan backup and it says sd-ext not found sd-ext skipped shows md5 then complete? Is that normal? Or should I be able to see it on sd? It seems as though it has taken up space but wanting to be sure? However.. Thanks so much

That's for if you have an a2sd partition on your sd card.
I like to break stuff!
So its ok? That means it is on my sd? Just trying to be sure since the backup isn't obvious by name. Maybe it is but I haven't seen it. Or maybe I've overlooked it? Any advice on what it would be labeled as?

No it skipped the sd-ext partition during backup since it doesnt exist. Your backup location depends on if you chose backup to internal or external
I like to break stuff!
It doesn't let me choose external and also now I cannot move aps to my sd card? Says unable to move ap? Is that due to flashing the new recovery? I followed the steps and it rebooted correctly however now it saves nandroid to my internal only and won't allow apps to be moved to sd? Any advice? I've looked all over and am somewhat confused.

Depending on the cwm version It does it automatically if you just choose backup but it should give you option in backup menu below to backup to internal sd card. On my phone it's always been on extSd/clockworkmod/backup.
If you Mobile Odin agats New FL16 repack, it gives you option for sure

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.

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.
