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.

(you can read about it here http://www.google.com/support/forum/p/Google+Mobile/thread?tid=44db6d8e31129d4c&hl=en&start=200)
i installed cm7 and thinking it will be helpfull,the freezing is the same.
when go back to the original rom i could get the google rom update to fix the problem

[Q] downgrade
can i downgrade to 2.3.2 using a nandroid

yes you can
just download the version that you want, copy it to the usb, reboot to CWR, and select restore, wipe data, wipe cache, wike kalvik, reboot, you're done, enjoy

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

[Q] Best way to downgrade from GB V2.0.2 to Infused V1.5.3?

I am on GTG's GB ROM V2.0.2 but want to go back to Froyo v1.5.3 as i am seeing some issues like phone freezing way too often. I had backed up V1.5.3 using ROM MANAGER. Can i just go to CWM and install v1.5.3 backup? OR do I need to go to stock ROM 1st? Any help is appreciated! Dont want to brick my infuse

For whatever reason my back ups did not work (i think it is a number of variables like pit this vs pit that and green vs red clockwork but didnt spend much time on it)
sooo.....i did the 1click back to stock.. Super 1click root basically staryed over...reinstalled recovery and then flashed my backup.
I am still playing with the whole "why cant i just restore a back up" but dont have much time this week to mess with that this week

The easiest way to backup using titanium backup, and then flash 1.5.3 using CWM and then factory reset using CWM. I have done this many times, and am willing to help you if you need.
THIS WILL DELETE YOUR DATA.

Just went back to Odin - Stock ( Root+3e), then installed V1.5.3, nothing was deleted from SD card... just the apps
Will now only upgrade to GB once ATT releases GB, had too many issues with Roger GB!

You cannot restore a froyo backup from a gingerbread cwm recovery. You need to go to stock first using gtg's unbrick. Then I suggest after the first boot to do a factory reset from the settings within the phone not cwm. Then root and flash a froyo kernel using sgs kernel flasher from the market.
After that you can restore a backup with no problems.

That's exactly what I said above...but loglud is either misreading what the op is trying to do... or claims to be doing so from cwm...

Just realized tonight that if you use this file in this thread...you go back to ROOTED stock, with modded 3e recovery...takes a few steps out if you are just trying to get back to rooted stock

That's right.. need to go stock.. this is what i did
-> From GTG's GB V2.0.2, went to stock ( root+3e recovery) http://forum.xda-developers.com/showthread.php?t=1092021
-> Then install V1.5.3 froyo in CWM. Wipe data/factory reset for safe side. Just the Apps get deleted.. Data on Internal SD is not wiped.

I can confirm that this method works, I just did it......just follow gtg's instructions for performing a full installation if already running a custom rom.....be sure to do your backup first!

trying it now...I think the factory reset is the step I was missing
edit: indeed..that is the step I was missing
Thanks guys!
1. Back up current GB rom
2. Flash Froyo ROM
3. Factory Reset via CWM
4. Boot
5. Let system settle
6. Reboot into recovery
7. restore back up of said froyo rom
worked like a charm

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
BEST DAMN PHONE BECAUSE WE HAVE THE BEST DAMN DEVELOPERS!

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
Sent from my Nexus S using XDA App

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] Q flash with stock CWM

Hey all , hope u rocking with your tabs.
anyway, I decided to move on and divorce my stock rom forever
I just would like to ask about a few little things before i get starting flashing.
1 - can i flash Panaroid(Cauz it's awesome and very fast software cycle) with the stock CWM?
2 - if i decided to return back to stock ICS, i will have to wipe data then and would that make me vulnerable to the famous brick bug?
3 - how to backup my stock rom just in case?
4 - what's the biggest sacrifices i will make due to this migration?

well, 2 days now and no one answers these questions :S

Well I have Paranoid installed and its perfect. I backed up my stock ICS and I have a backup. That's all.

Hi I am newbie as well. Still see and learn from this great helpful website. I would like to share my experience to play around with custom ROM. and so far still safe. These steps are from what I have done although I have not used the wonderful [ROM][JB : 4.1.2][CM10 Hybrid][P6800\P6810\i815] Paranoid Android v2.22 [17/10][WIP], I am still waiting for the nearly perfect of this rom. .
I am still satisfied with [ROM] Singha ROM Version 1.1.1 (SEP 26 2012). http://forum.xda-developers.com/showthread.php?t=1886370

1 - can i flash Panaroid(Cauz it's awesome and very fast software cycle) with the stock CWM? It is better using CWM instead of Stock recovery. I am using old version Locerra's recovery at this http://forum.xda-developers.com/showthread.php?t=1542897&page=13. Works perfect so far.
2 - if i decided to return back to stock ICS, i will have to wipe data then and would that make me vulnerable to the famous brick bug? if you have downloaded stock ICS thenI would suggest using CWM when you are installing from zip file. So far I did the bellow steps if using CWM :
1) place on internal SD
2) reboot to CWM
3) wipe data/factory reset in CWM
4) wipe cache
5) advanced > wipe dalvik, wipe battery stats
6) install .zip from INTERNAL SD
7) reboot
Another method is using mobile odin or PC Odin to flash with Stock ICS. You can see at this http://forum.xda-developers.com/showthread.php?t=1469635
3 - how to backup my stock rom just in case? You have to install CWM Recoverry. TWRP http://forum.xda-developers.com/showthread.php?t=1809295 or Locerras' recoverry
4 - what's the biggest sacrifices i will make due to this migration? see The OP updated log. It is nearly perfect and there is still bug. But it depends on individual's opinion.

oh, thanks very much, cakrabayu.

How Do I Backup the Operating System?

I rooted my S3. I have not unlocked it.
I would like to backup the android operating system, the apps, and the data before I allow the recent OTA update.
Based on my research, I believe I can use titanium to backup everything except the operating system. How do I backup the operating system?
I tried the Volume Up/Power/Home Button restart. It gives me the option to restore but not to backup.
What am I missing??

Thank you for the speedy reply. I did a quick search and found quite a bit written on installing a custom recovery including on the S3.
It appears that I can only back up to a custom ROM such as ClockworkMod Recovery or TWRP Recovery and not the base ROM as it is on the phone now. Is that correct?
I have ROM manager on the phone so I expect the ClockworkMod Recovery would be the way to go.

Nope, CWM and TWRP are custom recoveries. You'll have to install one of those in order to backup. Go onto the app store and search for EZ Recovery. Use that app to install the recoveries(it's the easiest way for someone new). Then you just boot into your recovery and do a backup of your current setup.

Download EZ Recovery and flash CWM then boot into recovery and choose the backup option.

Custom recovery will backup stock rom. You will not be able to install any OTA until untill you Odin back to stock.

Thank you for the replies.
I guess I should have included in the initial post that all I have done is root the phone......I think.
I never unlocked the phone with Ez-Unlocker
I never used Rom-Manager either.
I did install SD Speed Increase and increased the SD cache size from 128kb to 1024 kb.
Thats it.
Does this information change the previous recommendations?

No, just install EZ Recovery and follow the directions listed in one of the guides in the stickies.

Yes, if you have a custom recovery you cannot accept an OTA. The install will fail. You will have to Odin back to stock in order to take the OTA.

Thank you for the input.
There is a lot of information on this topic but its not easy to determine which of it applies to my situation. I feel pretty good about being able to Odin back to stock but I'm not sure I want to take the risk of doing that (probably not much risk) just to get the latest update.
I expect the best thing for me to do is decide to either 1) go ahead and install CM10 (I think that's the one I would want) or 2) go back to stock and stick with the Verizon software. I'd like to get Jelly Bean now, but I'm not sure its worth the risk. We'll see.
Thanks again!

If u use ez recovery and flash back the stock recovery u can then accept the ota just fine. As long as u haven't messed with any system files you are good. Then just re root it once ota is done.

Thanks for the info.
I have installed EZRecovery and it seems pretty straightforward. I'm still trying to decide if I want to go for a Jelly Bean ROM now or just wait.
I'll just keep reading until I'm comfortable that first, Jelly Bean will give me improvements worth the risk, and second, I won't brick the phone.
I have been fooling with computers since the 70s but Android is somewhat different and it will take a while to learn something about the architecture.
Thanks again.

If new I would flash an ICS rom first and get you a stable daily driver setup and backed up. Regardless of what you read all JB builds are buggy to an extent since they are all ports. The advantage of Android is as long as you have a stable Nandroid you can experiment with more advanced ports. Backup IEMI also and be careful jumping back and forth between AOSP and TW based roms. This is where the most problems come up. From what I've seen if flashed AOSP base it is best to Odin back to stock before going back to Touchwiz.

Or Twrp
I prefer twrp as it will allow you to name the backup from within recovery as well as some things cwm doesnt do.
