Ok, so immediately after rooting I created a nandroid backup. So, if I flash a rom (or anything else for that matter) and something goes wrong, I can restore my "stock" backup. im new to odin and curious to why I'd have to use it to flash the vibrant stock rom if I already have my nandroid stock backup? From what I gather, if I change the kernal, using odin will restore it back to stock, and nandroid will only restore system and data, but not change back the kernal. Is this correct or am I missing something vital that I don't know about odin. Sorry if this sounds confusing. Any help is greatly appreciated.

You are correct. As long as you don't need to restore a kernel you can use nandroid to restore to stock. And if you ever use your nandroid backup there is a stock nandroid backup posted in the development forum. I don't like using odin unless I absolutely have to (such as in a situation where I can't get into clockwork recovery or something)

Earlier I rooted my phone and flashed it with Bionix Fusion. All went well and it was working just fine. Although after looking through the new rom I remembered I forgot to save my contacts.... I followed the instructions on installing bionix and I created a nandroid backup. Somebody who similarly forgot to save his contacts said to restore the backup sync the contacts to google and then flash the rom over again.
My issue is that I tried to flash my backup and now its been stuck on the Vibrant screen for the past 10 minutes. What went wrong?
please help and ty for your time
well because I couldnt get the nandroid backup to restore correctly I ended up just going back and flashing the bionix fusion rom again and its booting up just fine. Unfortunately I feel that I just lost all my contacts. Anybody have any ideas? Did my nandroid backup just get corrupt somehow? Is there anyways i can somehow get my contacts from the backup?
Whoever posted that must have meant that you should make a backup before flashing any rom. If yiu did that, you could have went back to that backup with all you contacts intact. Its too late now, hopefully google synced most of your contacts.

If you are running Voodoo lagfix, you have to disable the lagfix BEFORE restoring
i did do the backup before flashing. But i guess it just got screwed up somehow. I've never used any lagfixes either
Which version did you flash? I'm going to guess you used one that did not have a stock kernel (JAC/KK)... you would have to flash the stock kernel before restoring a nandroid backup from JI6 or JFD since IT has a stock kernel. The nandroid does not replace the kernel, hence why it would hang at the Vibrant screen.

Do you mean oden when you say "flash the stock kernel"?
1. What is the difference between performing a nandroid backup after booting into recovery and doing one through Rom Manager?
2. Where are the backups saved and is there any chance of them being overwritten by flashing a rom?
No difference
In the clockwork folder, internal memory.
You will not lose this because the rom's do not wipe internal, just data (apps)
I need a bit of clarification. What exactly is a nandroid...if i assume that it is a complete back up of all data and apps, would i be correct? As you can see im a bit confused. I read this http://forum.xda-developers.com/showthread.php?t=734475&page=2 (just in case i wanted to revert back to a stock rom for what ever reason) is the nandroid used once you flash back to stock using odin to get everything back to stock or can you us the nandroid to get back to stock?
Ive searched on here and cant really find a straight answer.
Thanks for the help!
So i'm pretty noob with all this stuff but i finally decided to try flashing my phone and, in the end, ended up with a "bricked" (or the extent a vibrant can be bricked) phone. Thanks in advance for the advice.
what i did
I followed the flashing guide in the sticky post "** GUIDE - TIPS - TRICKS ** Last Update 12/03/10 ** READ BEFORE ASKING" and everything worked great. I downloaded Rom manager, made a nandroid backup of my stock rom, flashed it with bionix fusion and everything worked great. I didn't do the titanium backup and there was an app that i needed to use the next day so on the way to work, i decided to restore back to the stock thinking that i could go back for the day, use the apps that i needed and when i got home got home, back up my apps with titanium back up and restore again back to the bionix fusion. So i did that. I went to rom manager and I first backed up my bionix fusion rom and then tried to recover my stock rom. When the phone restarted, it didn't go past the vibrant/samsung screen.
The question...
what went wrong? based on some reading i think it has something to do with the kernel but i'm not really sure.
but the real question is, how do i avoid from this happening again? did i do the recovery wrong? what's the best way to unbrick my phone back to stock without losing any data on the phone. is it possible????
at this point, i can go into download mode. what should be my next move?
Thank you again if you can provide any insight.
*edit*
So looking at some posts, I looks like I need to flash the stock kernel. can anyone tell me how to flash just the kernel using odin? I've never used it and I can't seem to find anything on flashing just the kernel. Thank you.
Problem SOLVED!
ok. not completely solved T_T.
What i've done.
I've flashed back to stock vibrant firmware and that works fine. When i try to restore my nandroid backup, and it reboots, I get stuck back to the same place i was. I made two nandroid backups and tried them both but neither of them work. am i doing it wrong? I have even re-rooted my vibrant and downloaded rom manager again and tried it through there and still get the problem. have tried it about 4 times now with no luck.
Again, any help is appreciated.
Nandroid doesnt replace the kernal

Exactly, nandroid doesn't replace the kernel. If you want to run a nandroid restore, you have to either flash the rom the nandroid was created on, then restore (safest imho), or flash a compatible kernel for the rom from which your nandroid was created, then run your nandroid restore.

Pretty sure this was in the sticky too
I know that when you do you a backup, it backs up your rom and kernel.
But does it back up your modem? I did that whole shebang to get the ED01 modem and would rather not do it all again if something goes wrong.
Thanks
nandroid backups back up /system and /data afaik, and with the new CMW 3.X I believe it backs up the kernel as well. There is no method to backup the modem, but I'd love to know what you think you're going to do that will mess up the modem, because whatever it is, you're likely going to want to use ODIN to get back to fully stock anyway as nothing besides Odin/Heimdall and OTA updates do anything to the modem.
Cool. That's all I wanted to know. I wasn't sure about everything it did. Thanks.
My question:
Is it ok to recover a Nandroid backup that was created on a "Stock Samsung" ROM (meaning right out of the box) while you are currently running a Custom ROM? Or do you have to flash a Stock ROM first?
Same question goes for vice-versa.
Here are the details and why I am asking.
I searched and found an answer, but the poster was not 100% sure.
I have a stock 2.2-based Nandroid backup.
I flashed Biffmod ROM.
I realized I wanted to make a backup of one of my apps from my stock environment.
So, I recovered my stock 2.2 nandroid backup.
Recovery failed in the middle, and "soft-bricked" my phone. << this is why I am asking
I don't know if that is the correct term, but it wouldn't get past vibrant screen and couldn't get into recovery mode.
Incase you're curious, I was able to get into download mode just fine so no actual Bricking here.

you should be able to
im guessing it 'didnt work' because nandoird doesnt back up the kernel i dont think so you'll need to flash a compatible kernel seperatly after for the rom you backed up
You need to odin back to stock when coming back from a CM based (biff mod). I would suggest odining this JK2 rom.

This is 2.2 based and already comes prerooted and has busybox. Then restore your nandroid.
