How do I revert to a stock recovery image?

I have been searching for a stock recovery image for my I9020A.
My phone is going to be going back to Samsung for repair, I don't want to send it in with clockwork recovery on there. I have reverted back to Stock 2.3.3 and unrooted already (I can fastboot oem unlock again if need be).
Any help with this process would be greatly appreciated.

Moving from ICS Alpha11 to Official?

Hi,
I'm currently using Koush's ICS Alpha 11, I've downloaded the official 4.0.3 version and tried to rename it "update.zip" and flash but it fails.
I'd really appreciate any help.
Thanks!
Did you go back to stock 2.3.6 and flash in stock recovery
BEST DAMN PHONE BECAUSE WE HAVE THE BEST DAMN DEVELOPERS!
Oh, so I should download this:
Android 2.3.6/GRK39F/UCKF1 Radio/KA3 Bootloader
Official, signed, can flash with ClockworkMod or stock recovery. Contains recovery, radio and bootloader.
... rename it to update.zip and then back into CWR and then ICS?
Download stock 2.3.6 and flash it you will loose clockwork mod.you have to do this to apply the official
Rename it to update.zip
In fastboot mode go to recovery and select it with your power button
When you see the android question mark hold up and power again
Choose apply update.zip and bam your done
I forgot get voodoo ota root keeper from the market and run it before flashing the stock rom
Good luck and keep ne posted

Can't seem to find FULL stock 2.3.6 for nexus S, some links floating around the web are just the update packs (around 12mb), not full.

There's a stickied post right here on the forums (this forum, in fact). It has every OTA released.

You do not need to go back to stock recovery. Do it all from cwm recovery.
Full wipe and flash the 2.3.6 from
Flash the ota file.
Reboot. The reboot into the os will flash the stock recovery

Hey guys, I'm in a similar situation too, I'm on Carbon ROM and I was waiting for a Stock update. So is there any way that I can update and keep the root? Because I think when I'll flash the stock 2.3.6, I'll lose root.
ok so I went back to 2.3.6 stock, and susprisingly I didn't lose my root/cwr or anything, then I went into recovery again and tried installing update.zip (which is ICS official stock) but the same error:
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted.
When you go back to stock you need to do a wipe.

I did wipe partition as well as cache. let me try again though.
Format everything but sdcard. Flash the official 2.3.6 T-Mobile rom. Flash the official ota update for said rom and your good. You would have to have a the 9020t model of course

How do I format? from PC? delete everything from the mounted usb volume?
From cwm recovery. Mounts and storage. Just DONT format your sdcard. Your backups are there.

I don't have clockwork anymore. I see limited options now, and the title on top is "Android System Recovery <3e>", but I do see an unlock icon when the phone boots.
You need to reflash clockwork from fastboot. When you load a stock os it overwrites the recovery

I have no clue how I did it couple months back, can you please point me to a guide that shows how to flash cwr on 2.3.6? many thanks
What rom that is on the phone does not matter . You just need to get your phone recognized on a computer with fastboot. Then flash the recovery from there. Or just boot the recovery directly from fastboot.

[Q] Installing ICS 4.0.3 on Nexus S failed

Reverted to stock 2.3.6 (locked) and flashed update.zip (used VQ8PQk_V.zip) using 3e. I followed tutorial on the web.
Install aborted - signature certification failed. Should I flash the 4.0.3
using CWM instead? Thanks.
I think so ,you must flash the 4.0.3
Also did u rename the file to "update? Dont name it update.zip bc it will show as update.zip.zip
