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.

depends what you restore back to.
2.3.3 is the latest
Can't you just copy that 2.3.3 stock ROM zip file to SNS root and run through recovery?
Why would you go to 2.3.3 by choice? I'm dreading the day that it says i have an update.

I was the praud owner of a nexus s root. i upgrate to 2.3.3 and im keep root, but cant do anything because clockwork recovery dosent work, neither the superuser, etc.... I just whant to go back to 2.3.2
fastboot boot etc etc
Ok first of all, this is my dad's phone he wanted rooted with a custom ROM. I'm not new at all to flashing but I have the Droid X and Droid Bionic so I only know MOto. SO I performed the root (*****) and installed CM7 build on his Evo. A week later he was experiencing ploblems with gmail and GPS and not wanting to constantly hear complaining, I opted to install a new ROM that had an RC build . I chose Synergy with god mode (wanting to wipe it twice) and proceeded with the dalvik and cahce wipes only. I didn't format sys because the op didn't state that I had to.....well I left his house letting the ROM settle and now its in a bootloop. He's telling me via gtalk that it trys to come on but says "storage is full" and "android.acor" has stopped. Any solutions that I can give him to get him back up and running?
Did you nandroid...if so just restore that

You'll have to flash a new rom or restore a previous backup (if any was made).

Turn off the device, hold down the volume button and then the power button.
make sure you follow the 3 main steps before flashing/ restoring any rom or backup
1. wipe data/factory reset
2. wipe cache
3. go to advance->wipe dalvik
then proceed, and even though your motorola, it's the same through out all the phones
(have a photon and an evo3d)

Hey,
I've flashed hydro 4 in the past but my wifi didnt work, so I used CWM to restore ICS.
I now wish to flash cm10;
do I just boot into cwm, do wipe data, dalvik, factory reset etc
then flash cm10zip?
Is that all; I just dont wanna brick
One other thing, could I make a backup of the actual ROM once installed so I can go back and forth two restores without having to use titanium backup to reinstall everything?
Thanks a lot, reply greatly appreciated (and thanked )

BUMP
1) Always use titanium to backup your app data before flashing new rom.
2) Download and save to internal sd CM10 and gapps.zip.
3) boot into recovery. (I use cwm as I'm used to it)
4) under backup and restore, backup your current ROM. Just in case you know.
5) wipe, wipe, wipe.
6) install CM10.zip
7) install gapps.zip
8) reboot and enjoy.

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.
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?

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?

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.

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
Is it possible to return to stock without losing my data? My data really isn't that necessary, as I could make a TB backup and save it to the internal memory, but the main question is: Can I return to stock ROM without having to to wipe my internal memory?

no. of course you can set it for google to restore your settings, and apps with settings, but your data will get wiped.

Alright, thanks
Yes you can. Just download the stock factory image and extract it. Then using adb (I hope you know how if not tell me and I'll try to explain) flash the recovery, system, and boot images. That will restore your stock ROM, kernel, and recovery. Just don't flash the userdata image and all your internal data on your "SD card" will be fine. All you have to do is restore your titanium backup apps and all their data will still be there and your pictures and everything will all be available.

Cool I was wondering this too as I made a nandroid when I first started but not sure I had all my apps set up yet. From here I would just reflash twrp and reroot, correct?

Yes but you'll still lose your apps just not the internal data so make sure you backup with titanium. It'll be like flashing a new ROM.
