How to Downgrade Nexus s from ICS to 2.3.6 Gingerbread?

Hey I am desperately looking to find how to downgrade my nexus s from the terrible ICS version back to Gingerbread.. I have already tried to flash into 2.3.6 and 2.3.4 using rom manager but got an "installation aborted" response.. I have read here that I can also do it using Odin but couldn't find enough info to understand how to do it. Plus, I am a MAC user but in case there is no solution for it using mac Ill love to get some directions for Windows users.. Any kind of help would be appreciated..
Thanks

use this thread and download correct version for your phone model then flash through cwm. make sure you download full rom.

I already tried it but just to be sure l downloaded to right one.. Lets say I want to get any version of gingerbread(2.3 to 2.3.6) so which version I need to download?
this is my phone info
model number: nexus s
android version : 4.0.3
basband version: I9020XXKI1
Karnal version: 3.0.8-gb55e9ac

build numberIML74K
Thank you very much!

just like what sean1984 told you, choose your correct full rom phone version from that link
in your case is "basband version: I9020"

worse case scenario search for Odin topic
and you can use Odin to go back to stock

thank you guys for the help.. I tried to use worldclockmode with many rom versions and still unsuccessful... I think Odin is my answer.. Can someone give me direction on how to use it and whiere to get it.. I apologize I REALLY need help.. Thank you very much!!

odin doesnt work nexus s!
if you are stock then you might have to root

[Q] Help with Installing ICS on I9020

Hi everybody,
I'v got a Nexus S with original ROM (no custom ROMs), now running android version number 2.3.6.
I don't get ICS update, and after waiting for a long time, decided to do it manually. I have two questions:
1. Is the update stable for normal use.
2. How do I do the update? Where I find the update file? is there a good and simple guide?
My device details are:
- Nexus S
- Android version: 2.3.6
- Baseband version: I9020XXKF1
- Build number: GRK39F
- The phone was bought at BestBuy in the US, as a SIM free device.
Tnax for any help.
Dodo.

Which carrier are you on? Your device is most likely i9020T if you bought it at bestbuy. You can find the update.zip in THIS THREAD, and as far as install instructions, the video below is pretty good. (just skip to 1:40 and go from there) also keep in mind:
-the video says you need T-mobile nexus s. You don't. as long as you have the i9020T your good.
-The .zip file will have a different name than the one in the video.
So, go to the thread above, and scroll down to "FULL ROMS-FLASHABLE ROMS" and click on "Android 4.0.3/IML74K/XXKI1 Radio/KL1 Bootloader" It should start downloading right away. after that, just follow the steps in the video.

I believe you are using the same phone as me...I am on FIDO in Vancouver Canada. I am using the CyberGR MOD V.7 which can be found in android development section. Extremely Stable i.e no issues at all..with everything working. You gotta jump the ship..do it do it...

Are you rooted?

I'm assuming, since the OP doesn't know how to flash a ROM, that he is NOT rooted...

Thanks lumin30
Both of you, bug Mobilicity for a stock image to restore your phone. lol. Wind won't give me one but maybe Mobilicity will.
I can get it to about 90% stock right now and I'm sure I'll get it almost there. The problem is this. To dump the stock phone, we need it rooted to gain access but the only way to get root on 2.3.6 with the latest patches, is to flash a rooted kernel, which is great but then prevents us from dumping the stock kernel. It's a catch 22. Need a hacked kernel to dump the kernel but flashing the hacked kernel erases the stock kernel. lol.
The package linked by lumin30 will get you rooted, and all the options from there are explained.

tnx
tnx

Hi,
I will check with mobilicity and see what i can do to get the files from there. I really doubt if they would do it for us.
Meanwhile i am trying to get the files from someone who has a official unlocked phone purchased which is carrier free.
He hasn't tampered with it yet.
let me see what he can do for us.
Thanks

[SOLVED] Rooting Nexus S I9020A

Hello,
I've been searching this forum for rooting guides and i came up with this one and it looks pretty straightforward to me but i have messed up samsung phones in the past so i thought i'd post here just to get some advice. I have quite a lot of experience in unlocking and s-off htc phonesand i'm told samsung phones are way easier.
So please correct me if i'm wrong: basically i just need to have the samsung drivers and adb/fastboot to unlock the phone, then flash cwm recovery and flash any rom i want?
I'm currently on Gingerbread 2.3.6
Baseband I9020AUCKF1
Build GRK39F
Kernel 2.6.35.7-gf5f63ef
P.S. If anyone could recommend a stable 4.2 rom that would be fantastic

newbie w/ samsung galaxy s4 G

My rooted phone will not let me into my playstore, i think this could be do to rooting and then doing the android update, or maybe the freedom app i downloaded at one time. It also says I lost root. Anyways I was stupid and thought I new what I was doing and think I may have really screwed up my phone. Will flashing stock firmware fix this? think i have looked through the threads already and I think I have a good handle on this whole flashing stock firmware. My question is if I give you guys my build number/ phone info can you tell me what exact firmware I need to revert to stock? Build# VRUFNK4 for a SCHi545 samsung galaxy S4 G. Let me know please. Thanks!

The best way to flash back to stock is using Heimdall one-click. Complete instructions are available at: http://forum.xda-developers.com/showthread.php?t=1470716
