I have a feeling that you would have to flash with nandroid stock backup. At least according to this guide i found elsewhere. (theunlockr dot com/2011/01/20/how-to-unroot-the-nexus-s/)
I. Before You Begin
1. This will return the phone back to the stock ROM and put you at build GRH78.
2. Use this method to start over, or to send your phone in for warranty reasons.
3. You MUST have a custom recovery image to use this unrooting method.
4. This WILL WIPE everything on your phone.
II. Create a Nandroid Backup
1. Turn off your phone.
2. Turn it back on by holding down Volume Up and Power until the green Android shows up on the phone.
3. Using the volume buttons and power to select, select Recovery from the menu.
4. Once in recovery mode, select Backup and Restore then select Backup and wait for it to backup your current ROM.
5. Once it is done, select Reboot and wait for the phone to reboot.
III. Flash the Stock Nandroid Backup
1. Download the stock Nandroid Backup and save it to your computer.
Stock GRH78 Nandroid Backup
2. Extract the .zip file somewhere on your computer.
3. Plug your phone in via USB cable and mount the internal storage so we can transfer files to it.
4. Find the Clockword folder on your phone’s internal storage and open it, then open the Backup folder inside there.
5. Copy the 2010-12-22.21.06.07 folder from the .zip file you extracted and put it inside the Backup folder we just opened.
6. Turn off the phone.
7. Turn it back on by holding down Volume Up and Power until the green Android shows up on the phone.
8. Using the volume buttons and power to select, select Recovery from the menu.
9. Once in recovery mode, select Backup and Restore then select Restore and choose the 2010-12-22.21.06.07 backup and wait for it to restore the phone to stock.
10. Once it is done restoring, select Reboot and wait for the phone to reboot.
11. Once it does reboot, turn it off and then back on normally again (this is to clear out the recovery image and bring that back to stock as well).
IV. Relock the Bootloader
1. On the phone, go through the setup process clicking skip where ever possible.
2. Then hit Menu then Settings then Applications then Development and make sure USB debugging is checked ON.
3. Plug the phone in via USB.
4. Open a command prompt on the computer by clicking on the Start menu and typing cmd and hitting enter in the search bar.
5. Then in the command prompt, type the following with hitting enter at the end of each line (this is assuming you did our How To Root the Nexus S procedure):
cd\
cd c:\androidsdk\tools
adb reboot bootloader
fastboot oem lock
6. The phone should relock the bootloader and you are now fully stock and completely ready to send the phone in for warranty

[Q] Please clear me up :)

I have a defy with 2.51 from Red Bull in Austria.
I want to install CM7
what i have done so far:
rooted
recovery installed
nandroid backup done
what i want to know:
If i need to send it in for repair, is everything i need to do to flash back the nandroid? or is this not possible because of the lost of downgradability on 2.51?
it would be nice form you to tell me this things
If you have a nandroid of your system, and a fixed SBF of your 2.51, all you need to do to send it to warranty is restore your nandroid then flash the fixed SBF.

if you don't flash the full SBF, your downgrade-ablility is fine.
here the safe step to install CM7 to keep your downgrade-ability:
FROM ECLAIR
1. get root, install recovery app, reboot
2. place nandroid backup of 3.4.2-177 to your sdcard
3. turn off usb debuging, go to your custom recovery app: tap install recovery (allow root access when needed), tap reboot recovery
4. from custom recovery, wipe data, then wipe cache
5. then restore nandroid
6. choose reboot system now, BUT IMMEDIATELY go to bootloader (press and hold vol.up immeditely after phone reboot)
7. defy is in bootloader state, connect usb (make sure your computer has usb driver installed), open RSD-Lite 4.9 to flash the Fixed SBF of 3.4.2-177
8. let the process begins and wait untill phone fully starts.
now you in Froyo 2.2.2 (build number 3.4.2-177) state, with still have a downgrade-ability.
9. place CM7 beta5 zip and google app zip to sdcard root
10. make sure that nandroid backup rom you just restored is rooted (there is superuser app on there),
and UNINSTALL any custom recovery app you can found (usualy named SD recovery, System Recovery, etc)
11. install bootmenu instead (there's a custom recovery inside that bootmenu)
-download this file (bootmenu), create folder named "bootmenu", and extract zip files into that folder.
-copy "bootmenu" folder to your sdcard root (it should like this /sdcard/bootmenu)
-turn on usb debuging
-do this from terminal emulator or with adb in command prompt:
Code:
$ su [COLOR="Gray"](look up your phone immediately, allow root access)[/COLOR]
# cp -R /sdcard/bootmenu /data/bootmenu
# cd /data/bootmenu
# chmod 755 *
# ./install.sh
[COLOR="gray"]--------- it should says installation done and says please reboot. but don't reboot now.[/COLOR]
# rm -R /data/bootmenu
--------- reboot now
12. you will automaticaly go to bootmenu, choose boot, and set the default boot to 2ndInit
13. go back, go to recovery>custom recovery: wipe data, then wipe cache
14. choose install zip from sdcard, choose CM7 beta5 zip
15. choose install zip from sdcard again, choose google apps zip
16. reboot system now, first boot seems much longer
17. it's done.
if you want to go back to eclair
1. turn off usb debuging,
2. copy nandroid backup of your ECLAIR to sdcard, put it in /sdcard/clockworkmod/YourEclairNandroidFolder (must "clockworkmod" not "goapkrev")
3. reboot phone
4. have a attention, when blue lights is on while motorola logo shows, immediately press vol.down
-you will go to bootmenu, go to recovery>custom recovery
-wipe data then wipe cache
-choose restore, choose your eclair nandroid backup
5. choose reboot system now, BUT IMMEDIATELY go to bootloader (press and hold vol.up immeditely after phone reboot)
6. defy is in bootloader state, connect usb, open RSD-Lite 4.9 to flash the Fixed SBF of your Eclair Build 2.51 Aus Red Bull
(must a same build number with your nandroid backup, i can't find a link for that build number)
7. let the process begins and wait untill phone fully starts
8. it's done.
now you back on Eclair
thank you very much

[Q] Need to return AT&T/BestBuy "S" to stock...

Hello, newb here (for now)
My nephew rooted my Best Buy Nexus S (AT&T) and installed Cyanogen 7, it works great, but I think I have a defective screen and I need to exchange it at BestBuy. (Screen Flickers/flashes at times)
The kid is gone back home and I need to get back to stock. Here's where I am right now:
- I launch Rom Manager (4.3.3.0) go to "Download ROM" and scroll down to "stock images" and download Nexus S 2.3.3, it downloads.
- Then the "Rom Pre-Installation" screen comes up and I choose all three options (backup, Wipe data/cache, Wipe Dalvik Cache)
- I press "OK" to reboot and get the Google Screen with the lock and it just stays there (I waited about 10 minutes)
- I pulled the battery, power on with VOL up and get to "Fastboot mode" (I think... screen with choices and android character?)
Anyhow, I've tried every option here and i cannot get it to load anything to replace the Cyanogen 7 Mod.
Maybe I need a stock AT&T Image? The one from Rom Manager is wrong?
With all of that said, I'm using a MAC.
Any pointers or suggestions?
Thanks!
I think my issue is that it will not go into recovery mode. When I choose recovery, ut goes to the google screen with the lock at the bottom and never gets past that.
For whatever reason, using ROM Manager to flash a recovery onto the Nexus S makes it disappear. I did this myself and it made the recovery image vanish.
So use fastboot to re-flash the recovery image.
Download this file: http://download.clockworkmod.com/recoveries/recovery-clockwork-4.0.0.2-crespo.img
Rename it to "recovery.img" and copy it into the "platform-tools" folder.
Plug the phone into your PC, and boot it into fastboot. Open a command prompt and move to the platform-tools folder, and type "fastboot flash recovery recovery.img."
When it's done, reboot fastboot and when fastboot comes back up, scroll down to recovery and select it. It should boot into ClockworkMod Recovery.
Thanks for the reply!
How do I get to the internal storage on the phone? (I'm on a Mac) Plugging it in, I only see the memory card

Access your phone's memory card from Mac and enter sdcard/ directory. sdcard/ is your internal storage where you should put your ROM, if you decide to flash ROM or any .zip file from CWM's recovery.

I don't know if I understood you but just to be sure; you get in recovery mode CWM and on reboot TWRP?
I don't think you will like this solution but probably you will get your phone to work again xD (you will lose your data)
First of all you need:
- Android SDK bundle (google it, you will find it) on your Computer
- And a Rom you want to sideload (In your case the Cyanogen Rom)
- Cwm
Follow this steps:
1. go to the SDK bundle folder you downloaded -> go to sdk
-> go to platformform-tools
-> copy your ROM (ZIP-file) inside that folder
-> and name it to ROM.zip (so you won't need to write down a longname in cmd afterwards)
2. go to the SDK bundle folder you downloaded -> go to sdk
-> now press [shift] + [right mouse button] on platformform-tools (folder) to open cmd
3. Reboot your device into recovery mode (use cwm)
4. Go to “Mounts & Storage” and make sure that you can see “Unmount /sdcard/” and “Unmount /system/” (If they do not show this automatically, just press each one once respectively as pressing just toggles Mount and Unmount).
5. Now connect your device to the PC.
6. Once the phone is connected to the PC type “adb devices” in the cmd. If it returns a long alphanumeric string the phone is successfully connected in ADB mode. (if not look out for a usb driver for your phone; most time the problem lies in there)
7. Now type “adb push ROM.zip /sdcard/ROM.zip” (replace the word ROM if didn't named it)
8. This may take a while so be patient.
9. Once the process is complete you’ll see a message like <12345678kb to 1234567kb> on the cmd window.
10. Now unplug the device.
11. Go to the main screen of recovery and perform factory reset, wipe cache partition and then in advance menu wipe Dalvik cache. (Now you will lose your data for sure xD)
12. Now go to install zip from sdcard and choose the zip file you just transferred.
13. Once the process is complete, reboot the device
Hope this will help you.

So I got to step 4 and I see the mount system but I don't see umount sdcard
Then mount system or skip this part
5,6 and 7 are the most important part.
Can you push the Rom on your phone?

I know I am repeating myself more or less (because I always edit my posts xD)
Well as long as you can push your file there shouldn't be sny problem

so I wrote the command and it sad "5143kb/s «241840314 bytes in 45.912s»"
then i went install the zip and I can't find it
ok i went and mounted the data , pushed the file and installed it, thank you so much
But now i need to install the stock backup that I did with TWRP
That's pretty weird xD Because you get the message for a successful transfer but can't find the Zipfile.
You could try to push the Zipfile again and don't wipe anything at all (because you already wiped everything) and try to find the Zip file again to flash it.
Btw what does CWM gives you as options if you click install Zip files?

Alcatel Flash or 6042D Stock ROM, ROOTING, CWM RECOVERY

I am not a android guy but faced lot of challenge in finding the Stock ROM for Alcatel Flash or TCL 6042D or Alcatel 6042D. Found one here but having few corrupted files due to which "settings" "message" and few others didn't worked well and in fact frequent crash. Fortunately I had another 6042D to my relative and I took CWM backup of that device and would like to share with you.
Please follow the following steps and don't do otherwise, as only these settings worked for me, other settings may not work. Please Note That these steps are applicable provided that required driver for that device is installed properly.
STEP-A: Download these three files. Please add https: to all links.
1. Stock Recovery and Scatter File package.
//drive.google.com/file/d/0B-BBKAO9380FSkI0UUMxNDc4WEk/view?usp=sharing
2. SP Flash Tool Software
//drive.google.com/file/d/0B-BBKAO9380FRjV2dF81c1VLY1E/view?usp=sharing
3. CWM Backup package
//drive.google.com/file/d/0B-BBKAO9380Fb0NoWTNTLWhtQjA/view?usp=sharing
4. Extract the three files
STEP-B: Recovery Install. No root required
1. Go to sp flash tool folder and run it.
//drive.google.com/file/d/0B-BBKAO9380FMU1NUlFZQzFVNWc/view?usp=sharing
2. Then load scatter for the device from "SPtool_stock_recovery_scatter_OT6042D" folder.
//drive.google.com/file/d/0B-BBKAO9380FRFZPRElfdDAwR0E/view?usp=sharing
//drive.google.com/file/d/0B-BBKAO9380FWmhXZmlDLU5oQzQ/view?usp=sharing
3. If scatter file loaded successfully then you will see "boot" and "recovery" is marked. You must unmark or deselect the boot file. Then double click the recovery file to choose a recovery. Do not choose the recovery from "SPtool_stock_recovery_scatter_OT6042D" folder.. Choose the recovery from "\clockworkmod\backup\2015-10-16.14.26.59\recovey.img". Then press download button.
//drive.google.com/file/d/0B-BBKAO9380FUmtsMHI2WTRMakU/view?usp=sharing
//drive.google.com/file/d/0B-BBKAO9380FQzJLNjB2cDNiQ2M/view?usp=sharing
4. Connect your phone to Computer USB. Then turn the Phone completely OFF. Then after few seconds you will see the SP flash tool is working and sending file. File transfer rate and status will be shown in status bar.
5. If things are ok then you will see a Green Circle as "OK" symbol. And you are done with installing CWM recovery. Now turn the Phone ON.
STEP-C: Installing Stock ROM
1. Copy the extracted "clockworkmod" folder to the root directory of microSD card.
2. Turn OFF the Phone and wait for vibration. After vibration press "UP VOLUME + DOWN VOLUME + POWER" key same time and wait to see Alcatel logo. Release the buttons.
3. You should see the CWM recovery screen. Now follow the steps
wipe data/factory reset
wipe cache
Goto Advance then wipe dalvic cache and go back
backup or restore
restore
Choose the file from "clockworkmod\backup\2015-10-16.14.26.59"
chose yes in confirmation screen
Wait to see "restore from SD card complete"
4. reboot system now. First boot will take some time . Have patience.
Links are from Google drive. Sometimes google does not allow download of zip files. Let me know if it happens.
Thanks and Jajakallahu Khairan
