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.
I've asked this question as part of another question in another thread, but never got an answer...
I have a T-Mobile Sensation 4G that's rooted and has an unlocked bootloader.
There is no custom ROM on it right now, it's still the original Android 2.3.4 with Sense 3.0.
When T-Mobile pushes out the ICS update. What happens to my phone if I allow it to load?
Will my phone still be rooted? Will the bootloader still be unlocked?
Or will my phone revert to a locked and unrooted state?
Or is there potential for damage?
I'd like the official ICS update because it will include a working T-Mobile Wifi calling app for ICS. But I would like to keep my phone rooted.
Thanks in advance for any answers and advice on this!

Are u s-off? By rooted do u mean with custom recovery an superuser installed?
Sent from my HTC Sensation 4G using XDA
If you are S-off or HTC Dev unlocked then no you will not go back S-on or be relocked.
You will lose root, but go to here for a guide on how to root the nee ICS ROM.
Now as far as if you being rooted there is some that say need to un root before updating. And there is some that say it does not matter. I am still trying to learn more about this myself, so to be safe I suggest you un root before you update.

+1 on that. I have a stock un-rooted backup just for that purpose. Nobody seems to have a definitive answer so it's better to be safe. IMHO, I don't think it would be an issue though.

with or without the engeneering hboot

Sent from my Sensation using xda premium
Its a complete load of BS that your phone won't get updates if its rooted. All you need is stock rom and stock recovery. To preserve your root use voodoo ota root keeper. Backup root before update, then as long as your s off, flash stock recovery in boot loader, reboot, get the update, flash an unlocked 3.32 firmware from development section firmware thread then flash a custom recovery in bootloader then restore root using the app and flash root tools from mikes stock rom thread in clockwork mod or 4ext which contains su binaries, busy box etc. Which should give you root back.

What happens if you are S-OFF? Do OTA updates check for S-OFF? All I have done is S-Off'ed my phone but not changed my stock ROM. Not rooted either.

S-off makes no difference either. The update will not check for it. All it looks for is modified rom or recovery.

Well I can promise you that my phone updated to ics from stock gb with root and I managed to restore it after the update. Its recovery that will stop it installing. This page holds tons of instructions on ota updates but halfway down it says that ONLY correct CID, Recovery and stock rom are needed.
http://www.htcsensationforum.com/htc-sensation-rooting/how-to-downgrade-upgrade-gb-lt-gt-ics-a-tutorial/
But I'm just saying its possible, if anyone wants to try it then go ahead the information's all there but if your not confident that you know what your doing then try something else or unroot it.

Well its hardly bloat, its a recovery, and its the only recovery that can apply official updates. And thats the only reason it would ever be used over clockworkmod or 4ext unless you wanted to stay 100% stock. But all custom recoveries stop an official update being installed that's why you need stock recovery if you wanna receive official updates.

last time i had an update was that htc watch app or whatever and i had to get my phone back to stock before i could update, im not that much of an advance user to know ways to keep root and all that during updates.
Just so I am clear as I am thinknig of just waiting for the official t-mobile update (using t-mobile brand phone but no on their network) now given my phone died recently after flashing ARHD and I am not sure if it's just hardware coincidence or something with the firmware or ROM.
So after I got my phone back from repair...I now have S-off, rooted, clockwork mod, and SuperCID. So if I want to just get the OTA update for ICS when it comes out...what do I need to do? Do you guys mean removing clockwork recovery? How do I put the old recovery back? And also, someone told me I need to change the CID back to the Tmobile one?
Hope to get some clarification here. thanks

Thanks...I read through that. Just a little confused about flashing the recovery...on one site..someone posted the "stock_recovery_ and "cwm_recovery"...are there only one version of "stock_recovery" or does it go by the brand of the phone? Is U.S. T-mobile recovery different than other HTC sensation recovery?

I read the instructions but am a little confused about one part. They talk about if I want to stay rooted after ICS update... I need to root the GB ROM first (done)...the flash recovery...change CID back to T-mobile...
Then run OTA update....then it talks about flashing custom recovery. But I thought it said the new HBOOT is locked so custom recovery is not possible. So how could one flash custom recovery after ICS update as suggested.
Also, regarding flashing stock recovery....on one of the links, there's a stock_PMG58IMG file....so it doesn't matter if mine is US-T mobile? I can just flash any stock recovery as there's only one?

If you're s-off then you can flash recovery with a locked bootloader.

Ok....i have a Skyrocket that i got that was already ROOTED. But i didnt like the launcher....so i used the Odin and put the Original non root firmware on it then factory reseted the phone. Now im on a stock ICS 4.0.4.
NOW...the phone is unlocked and im using it with T Mobile. But im only getting a Edge "E" signal....which is slow as sh**. My question is....(May be a dumb question but worth asking)....can i keep this Stock Firmware and flash some kind of Radio over it to get 3G/4G? Or do i have to flash a custom ROM to get that? Love the phone...hate the edge tho. By the way....i have the SGH- I727
first check your apn settings.
you have to flash a custom recovery first, then root it so you can flash a different radio, third link in my sig, you can flash any ics radio, there in my first link in my sig.
check your apn settings

yes, installing the recovery and rooting is still stock ics, you wont see any changes when your phone boots up, but its not true stock for warranty purposes because of the custom recovery
Hello, I am still learning about custom ROM's, boot loader, etc, so I apologize if my question sounds like a noob one. I have the S III and I have put a custom ROM, boot loader, Kernal, (and radio?). I want to put my phone back to a stock ROM and everything else as I want to sell it on ebay or somewhere else. Can anyone point me to where I can find the stock ROM's and other items to bring back my phone to its "Original" state (or whatever state it would be in if it were to receive the Verizon OTA updates?)
Thanks for your help!
download this image http://www.androidfilehost.com/?fid=23134718111254196 and flash with Odin. After flash once it boot up make sure you disable OTA update. If you have the latest 4.3 stock rom it's harder to sell on ebay. If you want pure stock once boot up just turn off wifi and 4g.
Thank You! One last question where do you disable OTA updates?

If you want to sell it as pure stock, just disable wifi, turn off the phone then remove the sim card, now you can sell the phone as stock. If you disable OTA then the phone is not 100% pure stock since you need to modify couple system files and root the phone.

Means it is exactly the same as OTA. Does not wipe data. No difference flashing it and letting Verizon update it except Odin will unroot for you. Must unroot or hide root to take OTA.

Sounds like you borked your radios. Or your APN is missing. Only thing can do is run that tar. Can try running Verizon Software Updater in repair mode. It will wipe and then flash tar. If don't fix have to get new device from Verizon.

Make sure you are in Global mode before try any of this. If go with Software updater it is going to update you to 4.4.2. Not sure if can stop after repair or not. If that 4.3 tar in odin don't fix this is about only option I know of. Since bootloader is locked cannot use the fixes we have for this problem.

I am on MF1 rooted and unlocked but I have had the phone since it's release and have no interest in installing AOSP ROMs. I do need root because I have to be able to use root explorer or similar so I can edit the "keys" system files to disable the "WAKE" function of the home key. I keep my phone in my back pocket and it constantly turns on if the home key has wake enabled.
Before I flash this I wanted to confirm that flashing this No-Wipe Factory Image with Odin, I can root with Towelroot and install Root Explorer? Would I also be able to install TW based ROMs like a new Clean Rom if Scott gets one figured out? Would I also be able to create nandroids using Clockwork or TWRP?
Lastly, Since my most recent install of CR 8.2 my phone's behavior has been a bit sketchy (random reboots, laggy, etc). I assume if I flash this stock image it should return my phone to whatever level of performance "stock" yields, without any of my current, likely self imposed, performance issues?
I have never had a phone this long and expect I'll get a new one whenever there really is a "next big thing", but I don't think we're there yet.
Thanks in advance.

I'm on beanstalked / MF1 rooted and unlocked of course. But I'd like to get the phone back to stock condition so I can sell it here soon.
