Finally got a nexus s, & wanna start experimenting with root & ROMs, but i used to htc sense phones in which i can just use stock rom exe to go back to stock ROM, how do i do the same thing with my nexus s, i mean if something goes wrong is there any way of going back to stock ROM,
don't say just do the nandroid, because that means rooting first, can somebody please help me on this one
starting experimenting
if you want experimenting with your NS you have to root the phone first. It is really easy to root the nexus s, just have a look at this tutorial:
http://forum.xda-developers.com/showthread.php?t=895545
and then you can make a nandroid backup, like what you said.
if somethings goes wrong anyway, there is a way to go to stock as well.
http://forum.xda-developers.com/showthread.php?t=884093
just try, in worst case you can go to stock
The answer is Nandroid.
Nexus phones are different. Super easy.
Fastboot OEM unlock
Accept the warning
Fastboot flash recovery blah.img
Make nandroid, mount it back it up etc. Then flash whatever rom u want.
If u want to go back to stock, nandroid recover then
Fastboot OEM lock
say yes and you're back to stock.
-Nexus S
It is NOT necessary to oem unlock the phone to flash clockwork or a custom rom. See this method here: http://forum.xda-developers.com/showthread.php?t=931865
Also, if you're going to oem unlock, be aware it completely wipes all data off the phone, including anything on the sdcard you may have put there (like pics from the camera).
Finally, the most bizarre thing about the original post is that you're willing to flash custom roms, but not to root? Huh? You're aware that most custom roms come PRE-ROOTED, aren't you? What's the difference? Just curious....
By the way, Google's own blog states they intentionally made this phone easy to root and add customizations to...it's extremely safe and easy.

thanks for the info, i said, i want a way to going back, i want root, why the hell not?
polandy posted above a perfect guide to return back to stock just as shipped through manufacturer. Just make sure you relock the BOOTLOADER for any warranty purposes. Now you can flash all you want and can go back to "stock". Here is the link again, http://theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s/

I misunderstood you. You can flash cwm without rooting first, I think you could try nandroid before rooting.

I didn't say a there was European version of the Nexus S (yet)...but it's well known that there is one coming. I said this was a European version of the ROM.
Did you read the thread that has the files? The first post says that the guy obtained it from Samsung service center in England. Then someone asked if there was a US version, and no one corrected him in saying that this one was or wasn't. Granted, Samsung England could easily have access to US ROMs from the Samsung mothership, so that alone is not proof it is European.
However, if you download the rar file from that thread, and unrar it, you'll see that it contains a file named "CSC_I9020_EUR.tar" which is clearly a EURopean CSC file, making this a European ROM.
The PDA file's images may be 100% the same as a stock US phone, but until someone flashes this stuff from Odin and somehow runs a diff against a stock US ROM, I'm not assuming it's the same thing just on faith. You're welcome too, of course.
What's interesting to me is that there is a CSC at all. I don't think our Nexus S uses it, or at least it doesn't use it in the same way as the Samsung issued ROMS do. CSC is carrier specific customizations, if you're not familiar with it; it's a way to add bloatware and carrier settings to the phone.

Hello all,
So I'm getting my Charge in a few days, moving from a rooted evo, so I'm new to the Samsung scene. I've searched these forums but still have a few questions about the current state of things concerning rooting the Charge:
1. Does CWM work fully yet?
2. Is ED01 currently the only version that can be rooted?
3. What is ODIN/HEIMDALL and what is it used for?
4. Is simply rooting the phone enough to flash roms, kernels, etc? I know with HTC phones you have to unlock some other stuff first.

1. It works except for nandroid restore, this is being looked at.
2. ED1 and ED2 have both been rooted.
3. odin is a samsung utility for flashing, heimdall is an open source alternative that works for mac/linux users also
4. no unlock necessary, samsung hasn't locked bootloader
so odin has to be used for everything when flashing something like kernels roms etc?

From my understanding no, but like you I come from HTC phones...so this is semi foreign. At the same time this allows me to see if what I was reading i understood correctly and begin to grasp these concepts...
The custom CWM that is flashed with jt's kernel, you can flash within there.
how I read it is, ODIN is what RUU is to HTC...
imnuts talks about it here http://forum.xda-developers.com/showthread.php?t=1082288
Odin is used to unbrick your phone incase you mess it up somehow. Unfortunately we don't have a full odin restore yet so for now try not to brick your phone. Cuz if u do you'll be stuck whistling for a while lol

The nice thing is that it is easy to create your own Odin packages, so things can be created in either CWM or Odin flashable packages. CWM is a work in progress, but is working well enough right now for most purposes (flashing stuff).
I've seen many different rooting methods for the nexus s but unfortunately they don't allow rooting without unlocking the bootloader like the samsung vibrant allows is there anyway I can root my phone without unlocking the bootloader?
why I don't want to unloack the boot loader because I'm fine with the stock ROM on my nexus s. I was really into installing ROMs and things with my Vibrant but the Nexus S feels really complete so I feel like I don't need to unlock my boot loader
Also for the first time I have decent signal in my house after switiching from my blackberry to android so I don't wanna change my baseband and my battery life is good too so I don't want to mess with the kernel
Really? You posted in the same incorrect forum twice with the same question cut and pasted. Nice work!

You know you can re-lock the bootloader with a fastboot command, right? And the little open lock goes away.
i'm sorry i accidentally reposted i pmed the moderator right away because i didn't know how to delete the post and this is the right section its a question...
i just have one question i can relock right but if i do unlock the bootloader will it change my kernel or baseband settings? i really couldn't care about the warranty and such
it's like opening the door....if you do nothing inside, nothing will happen
yes i get that but i can't flash back to the original recovery as of now and so no changes to the kernel and baseband alright thanks!!
also is there some sort of a "ODIN" availabale for nexus s because thats what I used to always flash my samsung vibrant back to stock. will OTA updates be affected if I root and unlock the bootloader?

Yes you can use Odin with Nexus S, but consider it the last resort because normally you can do everything via adb and fastboot -- that's the advantage of having a Google phone.
For OTA updates, I'm pretty sure it will not work because OTA update requires stock recovery but rooting requires you to flash a custom recovery.

Hey, guys-
I'm unrooted and running stock Android. I have all of my settings and apps exactly how I like them right now.
In the past, I've flashed different ROMs and Kernels. When I get tired/frustrated with them and want to revert back to stock, I usually just do the 1 click revert back to factory settings. When you do that, it... well.. erases anything and everything in order to get back to factory settings.
Nothing is broke. I just don't want to delete my SD card contents and lose root. I just want to revert to the stock kernel and ROM from another ROM and kernel.
I was wondering if there's an easier way to get back to my current settings on the stock Android and Kernels WITHOUT using the 1 click revert back to factory method? If there is, could you PLEASE tell me how to do it EXACTLY? I say that because sometimes people on here give instructions that are clear as mud. Thanks!
Factory reset does NOT restore kernels or roms. It simply wipes user data.
You're confused. What you really want is a nandroid back up
If you have ROM Manager installed, open it up and go to "Download ROM". At the very bottom of the list, there should be a selection that says "Stock Images". I'm pretty sure you can use that to get back to stock. I'M NOT POSITIVE, I've never tried it before. It may unroot your phone/get rid of clockwork mod recovery. Just a suggestion

That is to relock your bootloader. Just flash a stock rom in recovery with a full wipe, You'll be unrooted.
Stock roms can be found here.
http://forum.xda-developers.com/showthread.php?t=1063664
It's also wise to keep your content copied on a folder on your comp. 5 minutes of copying back and you got it all back. If you got all that sorted what you should always do is once you've got a stock rooted rom, run a nandroid backup/backup restore from CWM before you flash new roms / kernels.

Hi folks.
I just came into possession of a Galaxy R. I have, for some reason, never been successful at trying to root prior phones, and I need an unrooted phone for work. I am looking for the simplest way to flash this to a stock, unrooted ROM without screwing it up. I am on T-Mobile in the United States if that makes a difference or is any help.
What's the quickest, simplest way to get this phone to a stock, non-rooted ROM without bricking the phone or causing functionality issues?
Just flash stock ROM of your country through ODIN and do factory rest ......
Simple and easy way ....
I guess my problem is I've never had good luck with this whole thing. I'm not sure where to find whatever the most current stock ROM for the US. Would I just flash it through Odin?

...and you DON'T want to perform a Factory Reset.
Figured this out while returning to the stock kernel after poor performance on a custom one...
THIS WILL LIKELY NOT WORK IF YOU ARE ON A CUSTOM ROM
If you are still on the Stock ROM you can do this to get new updates from your carrier (I have only tried AT&T):
1. Unfreeze AT&T updater (if you have it frozen)
2. Use ODIN to return to stock WITHOUT performing a factory reset. AdamOutler has a thread HERE with the stock firmware download in the Android Development section
3. Boot up and check for updates
4. After you have updated, root it, apply your custom recovery, and/or kernel again
5. Hit the THANKS button below
All your apps and settings will remain. You may have to re-sign-in to some, but you should be good to go.

Yes, however if you are on a custom ROM you must perform a factory reset prior to or after ODIN, which will make you lose your apps, settings, etc.
If you are still on the stock ROM, you don't have to factory reset... which is kind of the point for people who want the update but don't want to factory reset.

Assumed as much, but wanted to be sure. I'm on this forum exclusively and hourly anyways lol. So much reading to be done!
Will updates be specific to carrier? For instance I'm on Telus in Canada so I'll need to wait for my specific update, download and flash via ODIN? (Since I'm 'custom' status and won't be able to OTA. Root only, stock recovery, kernel and ROM.)
And thanks btw!

Unfortunately I can't speak for anything other than AT&T since I don't have the ability to test any other carrier's devices... however the update will likely be pushed by your carrier with their proprietary update mechanism.
If you want to use something other than OTA, you can wait for a flashable zip when it comes available, which will likely be pretty quick after initial release.

Maybe a tad off topic, but if one were to follow the directions in the OP, wouldn't it still not work? You'd still have the custom unlock button with stock firmware, which would prevent it to look for any OTA update.

I thought the same thing, until I tried it and the OTA came over just fine. That's one of the reason I started this thread, so others would know they can do it.
The ODIN gives you back the stock recovery so you can pull the OTA.

Ok, how about if one follows your method and then updates via AT&T OTA. Would it then get rid of the custom unlock status? How does one remove this if they're not rooted with 100% stock? I don't get why it still shows it.

I am not 100% certain what all gets looked at when the firmware runs its "custom status" check. I do know that there are a wide variety of fixes/solutions that work for some and not for others... I have the custom icon, but it doesn't bother me, so I haven't done too much research into it.
