Want to go back

I recently updated my nexus S i9023 to 4.0.3 and dont like it, its very laggy! How do i go back to 2.3.6?

Restore a nandroid backup...

Choose a rom from here and flash. You'll probably want 2.3.6.

Before you revert to gb, you'll have to perform a full wipe, not just a factory reset. Open the Mounts menu in cwm, then format system, boot, data, and cache - then restore your backup or flash a different rom.

How do i do that?

I take it you're bootloader is not unlocked? You'll need to unlock your bootloader in order to flash a different (in this case older) rom.

Update to ICS for nexus s 4G

Sorry I've been out of the loop for a bit. I have my phone rooted but on stock GB rom. If I try updating the stock ICS rom OTA I believe I will get an error. What is the easiest way to update and still keep my current data? I don't mind if I loose root. Can I unroot then instal the update OTA? Any suggestions welcome, please help!

I actually unrooted and then updated to ICS. After keeping stock for a couple of days I ended up rooting the phone so I could add the tap-to-focus feature to the camera.
Or you could just flash the stock ICS rom that's available in the development section.

Ideally you should wipe data. But if you're already rooted, just create a backup with whichever recovery you normally use. Then try to update with the stock ICS rom update posted by swampgoblin. You should be ok. But I do recommend that you wipe cache and Dalvik cache.

U could make a nandroid, wipe, update, & selective restore data only. at least this way, if it all goes wacky, u got a current nandroid to restore...

[Q] Restore to stock

My nandroid backup was made after rooting, so after a restore from cwm (I was on jb deodexed) I was still rooted. I flashed a stock image from sammobile with Odin from PC and I lost root (that was my intention). All my apps and data are still here, did not lost anything. No wipe no cache clear nothing else. Binary count 0.
I want to be sure that when jb ota is released I'll be able to install it from the device without any issues.
Do I have to do anything else? I read in some posts that I have to flash the stock recovery, in others that the stock recovery is flashed within the stock firmware so I'm not really sure. Is there a way to verify?

try booting into recovery by holding down the power and volume up button at the same time until it starts to boot then release the power button and keep holding the volume up. This will boot into recovery and there you can tell if it's stock or CWM.

It's stock. After the nandroid restore from cwm when I wanted to reboot I was asked if I want to keep cwm or to restore stock, and I choose stock. I think I''ll do a wipe and whatever I can from the stock recovery. I'm just bored....

yeah and if all else fails when the update comes and you aren't able to get it then you can just factory reset and odin the stock firmware and then all should go smoothly.

I already did that
The red triangle in the stock recovery is normal?

+1 it's worth the money to always have that as an option, just make sure you follow the directions (pretty simple)

It was the first thing I did after flashing the jb. As I stated in my first post, everything is ok on my device, I just wanted to be sure that I didn't miss something and that I'll be able to receive and use future OTA updates. I guess I'll have to wait to be sure, no point in making a tutorial on this yet.

Return to Stock

I'm sure this is discussed already but I can't seem to find it so if someone can help me or point me in the right direction.
I have a VZW GS3 that I have rooted, unlocked the boot loader and flashed CWM recovery. I then made a nandroid.
The main reason I did this was because I wanted Jelly Bean, and since Verizon is the slowest, I didn't want to wait so I installed custom ROMs.
Now that Verizon has released JB, I want to go back to my nandroid and then use the OTA firmware update service to upgrade.
Am I missing anything along the way that's essential for this to work?
Will the updated software re-root and/or relock my bootloader?
Will this automatically update the Baseband from my current VRLG7 to whatever the new one is?

One other thing, Will I still have CWM recovery after this happens? or will it revert back to stock recovery? or do I need to manually do anything to the recovery?

You're doing this to ultimately stay stock? Do you intend on flashing roms again or no? If you did a nandroid just after ONLY rooting and unlocking bootloader then restore it. Here's a step by step:
1) boot into CWM, restore your rooted, stock nandroid
2) Download EZ recovery, flash stock recovery
3) Wait for OTA
The OTA will relock your bootloader and unroot your phone. The JB OTA will also update your modem, and everything else, to VRBLK3.

No, you will lose CWM if you do what I detail above. The OTA will fail if you still have CWM installed.

For the time being I intend on remaining stock, but I still want to root. Maybe once CM10.1 becomes stable, I'll go back to it, as of now I've had too many bugs with 10 nightlys and stable and 10.1 nightlys.

I don't recall, but it's possible I did it after flashing CWM recovery, would that make a difference?
Thanks for your help!

Nah I was just verifying to see if you modified any system settings or apps while on ICS TW. You should be in the clear as long as you reset CWM to stock recovery if all you did was root, unlock, then perform a nandroid.

before I restore the nandroid in CWM, do I need to do any wiping? cache, dalvik or full wipe?

No you do not, the nan will overwrite everything anyways. If you feel better then factory reset and clear caches, but it's not necessary.

thanks

I followed the instructions above and I'm back on my rooted TW.
When i try and update i get the following message:
Service Unavailable
To check for system updates, go to Settings > About device when service is available
What's wrong, how do i fix that?

searched around on google and a lot of people had the same warning error, multiple solutions were offered but none of them worked.
in the end, I ended up installing from odin completely stock unrooted, locked bootloader etc 4.0.4 (as f i want to return my phone to verizon) and once i did that it automatically updated to 4.1.1

[Q] Flashing a new ROM ?

I currently have CM9 installed on my SGS4G and it's been over a year since I had it and wanted to try something new. After browsing in the dev forum, I decided to try out the SlimBean 4.2.2.
http://forum.xda-developers.com/showthread.php?t=2233640
I was wondering will my phone be able to handle it? Its still on ICS 4.0.4. The first instruction says to factory reset/wipe my phone but I don't really want to erase everything. Can I just download the SlimBean rom and flash it while on my CM9? Will it change my ROM to SlimBean or will something really bad happen.

That would be what's called a dirty
flash only used if you are upgradeing your current ROM..
You will have all kinds of problems dirty flashing jellybean from ICS..
Back up your app data with Titanuim Backup and try restoring app data 1 by 1..But don't dirty flash JB from ICS follow the OP's flashing
Instructions.
