[Q] Way to tell what ROM from Nandroid

I have a few Nandroid backups and I was wondering if there was a way to see what ROM it's from without actually restoring from it.

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

I use rom manager also... So it's safe when backing up to add the name of the rom at the end of the date that it automatically designates for us? Thanks

[Q] Backing up EFS file - I747

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.

Use this post with instructions on backing up the correct stuff. http://forum.xda-developers.com/showthread.php?t=1801997
I don't believe the other tools backup the memory block needed. They probably back up the efs folder which for our phone is empty.

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

Backing up qcn through QPST for T889 TMOBILE

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.

Restore imei

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.

CWM Restore 4.1.2 to 4.3.1-> Different Phone.

My screen got broken, and I got a new phone from insurance. I was on 4.3.1, and did a CWM backup which was stored in secure area. I used ADB to copy it off to my PC>
I now have my new phone, and it is 4.1.2. I installed CWM, and copied the files from the PC to the Clockworkmod/Backup directory, now on SD card. When I try to restore, I get a MD5 check error. From both backups.
Do you reckon I need to do something special to restore a CWM to a different phone? Or something about the fact it is 4.2.1, and I'm trying to restore a 4.3.1 backup?
Any thoughts appreciated.

Well, I have tried several things. The backup must just be bad. CWM seems to always fail me when I really need it to work.
I would have used TWRP...but my screen was dead, and so couldn't control TWRP.
Sigh...

Well, that link is great. It does indicate how to restore the md5, and get the restore going. However, in my case, the data will not restore. So my CWM backup is no good.
Back to TWRP for me.
Appreciate your help.
