I am using the vhgomez ICS ROM. I want to just go back to stock, non-rooted GB to make a comparison.
When I re-lock the phone, I'll lose everything, right?

I believe you only lose everything when you unlock. Relocking will keep everything there. So wipe /data, /cache, /boot and /system, flash the stock rom then go back into the bootloader and "fastboot oem lock".
Why do you want to lock the bootloader though? It has no effect on performance and does NOT mean you are rooted. This only gives you access to flash a new recovery via fastboot.

That is a good question/point.
Once ICS OTA comes out, will I be able to receive the OTA if unlocked?
I have no problem unlocking it and re-rooting it in the future, I just want to bring this back to 100% stock to compare it to what I've been using.
You'll be able to receive the OTA just fine, though i would've just downloaded the OTA and flashed it manually regardless. If you just want to go back for comparison, there is no reason to lock the BL and making it more difficult by erasing all data later.
You can even make a backup with CWM of your unrooted stock GB ROM when unlocked so you can get back to the base ROM with your settings and apps directly available. You can even better compare by just switching CWM backups and run the same apps etc.
I think SComp23 just need to re-lock the BL to make it just like when it comes out from the box, right?
agree with Harbb..
just wipe them all.. then re-lock using fastboot and flash your GB ROM
There's fast boot images stickied in the dev section. Just follow Pete's instructions and you'll be back to stock gb.

OK I have a question... basicly I really want the UK sky go app as I'm in the UK.... but it doesn't work on ics... so I was going to go back to gb just to watch sky go on the odd occasion and the rest of the time back to 4.0.3 ... can I do that through restore or will it cause issues
So basically flash stock gb .. use sky go... flash back to my backup of code name android + matrix ?
Doable ?

Just make two backups with CWM. One with all your apps on ICS, then one with all your apps on GB. Whenever you want to switch just restore the other, no more fiddling about.
Dual boot would be nicer, and there are some options, but i've not tried them and might be unstable or not provide a classic dual boot environment so to speak.
Yep that's what I wanted to hear ... where can I get 2.3 for 9020
All the ones iv seen cone with stock recovery and non rooted

I've not tried too many GB ROMs to judge, but i hear Oxygen based ROMs (which i intend to test eventually) were great, and obviously CM7 is up there. But you can just flash the bog-stock ROM, then just flash su.zip and fastboot CWM for your recovery. Set it all up, and THEN do a backup with all of your apps and settings ready to go. The same applies with ICS, of course.
Ah kool I see . So I have to set it all up first with recovery then backup....
Where can I get bog stock for 9020 though Europe version
Or is there not just a rooted gb stock rom that I could use ?

i9023 Stock ROMs
Grab the 2.3.6 GB FULL ROM. Then download the latest Superuser.zip, wipe, flash ROM, flash su.zip, reboot and rename /system/etc/install-recovery.sh to something else, then go back to bootloader and fastboot CWM again. I dunno if there is a rooted stock 2.3.6 anywhere, but i know that ROMs like Oxygen or CM7 are pre-rooted.
this is for 9023 though... im on 9020?
im also having manjor issues with my ADB atm as well. it worked fine before i installed the windows 8 preview... now i cant get it to work
The Europe version is the i9023 (SC-LCD), isn't it? Regardless, links to each Nexus S version here. Choose which is appropriate, and check behind the battery if necessary.
not sure mine is def the 9020 super amoled version though, thanks for the help. but ic ant adb atm

I can attest to this. Loved Oxygen when I was using GB user-made ROMS.
Let's say I want to flash a rom and made a backup thru CWM of my stock rom will I be able to keep root if I flash it back to the stock rom ?
II'm doing this cause I care most about no auto brightness issue than the actual advantage to go with a custom rom.
Thanks
Why don't you just root your stock ROM then? You need to be rooted to flash CWM recovery anyways..

If your ROM is already rooted, and you're restoring it from CWM, yes. If you're using fastboot to re-flash the stock ROM, no, you'll have to re-root it.
I'm kind of confused about what you're asking, though. Can you give more specific details? Are you going to flash a different ROM and try to flash the stock ROM, or parts of it, on top of the new ROM? I wouldn't do that unless you're very sure of what you're doing.
Hi all,
I'm sorry about my stupid question but I really don't know nothing about that . I had rooted and flashed my NS and installed the matr1x kernel (very good btw), and now I knew that JB will be available to NS. My question is, need I back to stock kernel to receive the update?
Thanks

You have to understand that installing an OTA (official update) on a rooted device regardless of what kernel can cause problems, as it did with my Nexus S before. I suggest you make a NANDroid backup at all times before you install any ROMs, official or Custom. You can also use Titanium backup and others.
There's still a slight while until the new JB 4.1 comes out. It's suggested that you install a Custom JB 4.1 ROM for your Nexus S as though you don't cause any problems. I think it's OK if you do it with the kernel pre-installed. But people always install the Custom ROM THEN they install the Kernel, I think installing a new ROM always overwrites the kernel, if it comes with it.
EDIT:
In short, wait for the JB Custom ROM and you don't have to revert back to stock kernel, when you do the update it will automatically overwrite. Most Custom ROMs come with Stock/ordinary kernels. So then the user can flash whatever kernel they like in your case, matr1x.
Wish you the best of luck, and I am waiting for the Nexus S JB to come out as soon as possible
Ota binary patches the boot image iirc. So it can get all messed up.

A NANDroid backup is a internal memory backup. You can create one by booting into Recovery (Power off your phone and Hold Power and Down on your volume buttons.) If you rooted your phone and unlocked your bootloader (that's what you had to do to flash a new kernel), you should be able to load ClockworkMod or TeamWin Recovery and do a backup of your phone.

There's one rom but it's a port from the SDK and the amount of major bugs is high so it's not recommended but you could try another custom rom meanwhile, I can't go back to stock after trying custom roms, like AOKP and Cyanogenmod 9. Make sure you backup your apps and some settings (not everything will be compatible between stock and custom so pay close attention to which system setting you'll backup) with Titanium Backup.
To sum it all up for you
There's a Jelly Bean release which is unstable and has no sound, and will not be fixed until the REAL version comes out.
NANDroid backs up the whole internal memory on the phone including the system, it can be done from clockworkmod recovery.
Titanium backup, backs up specific settings and information that you choose, available from the playstore.
You don't need to unroot or go back to a STOCK kernel in order to flash a CUSTOM ROM. DO not however flash a STOCK rom after rooting, as at times that can cause problems.
If you want to go back to a STOCK ROM after rooting a device, there's a way, check this guide
http://forum.xda-developers.com/showthread.php?t=1063664
and choose your Nexus S model: To acquire model, go to Settings - About - Baseband version. if it says I9023 at the start that's your Nexus S's model
Choose one of the Fastboot Stock ROMs and use the Fastboot method to flash the ROM. That is a good way to go back to STOCK ROM if anything bad happens
By the way you should expect the new OTA official 4.1 update for the Nexus S to be on your model's page.
NOTE: Using Fastboot to flash a ROM is very clean. However this will delete all your data and if you do everything correctly will lock your bootloader and unroot your phone. So use Fastboot only when you really feel the need to.
Cheers
and stay tuned for Jelly Bean :victory:

That means, when I receive the official 4.1 update notification, I should unroot my phone first and just install it after?

OK first off, do not install the update using the system update method from about, as that is a 100% stuff up if you're still rooted or on a Custom ROM.
However to update I think flashing a stock ROM but USING Clockworkmod works fine!
Someone please confirm, as I am not 100% sure
However what I am sure about is that if you run into any troubles installing your STOCK ROM using Fastboot is very very good and clean, however there are 2 things:
1. You will wipe everything COMPLETELY
2. You need the ROM to be in a fastboot format kind of way for you to flash it
There's a guide and everything for fastboot.

Personally I will wait for a custom ROM for 4.1 if it doesn't take too long as that's guaranteed and will obviously be faster and safer to install on a ROOTED device.
Someone still confirm if installing Stock ROM while over Custom ROM while ROOTED through CWM is OK or not!?
Hummm, ok...
I'm already using the Stock ROM, I just flashed a new kernel, and I prefer install the stock kernel and unroot my phone. Just to let it clean.
After I install the JB official update, maybe I flash and root again, depends of Google :laugh:
Do you know where can I download a trust official 4.0.4 kernel from the forums? My phone is a Nexus S I9020AUCKJ1, Version Number: IMM76D
Thanks!!!
Ok so i've finally decided im ready to unlock and flash. My question is this: whats the deal with returning to stock and redoing everything on certain roms? Can anyone explain to me the variables here?

once you have your device rooted and have a recovery installed, make a nandroid back up your stock rom, flash whatever rom you want, then if you need to go back to stock rom, just flash the nandroid back up you made. If you want to go 100%, then you will have to find the stock recovery image, and flash that over your custom recovery as well, then just use OTA Rootkeeper... and temp unroot your phone... and viola, your 100% stock again.... but if you plan to go back to 100% stock then DO NOT UNLOCK YOUR BOOTLOADER!! there is no way to lock it again once you unlock it.
I think it's worth while to note
currently the only custom recovery that is able to flash stock is CWM
TWRP is not able to flash a stock rom

If you flash a stock ROM using CWM you will lose all data on your device, including any backups you made using CWM. So be sure to backup those files to your PC (they're located in the clockworkmod/backup folder of your internal storage) before flashing the stock Asus ROM.
I've been changing my ROM's throughout the day and have basically memorized the process of flashing CWM, root, and ROM's by now

not sure if I understand your question right, but yeah you can use your stock rom when you root or flash cwm. Untill you wont wipe anything within CWM, theres no reason you coulndt use it. But dont forget to do backup of your stock mate.
I think part of the confusion is defining what "stock" means, and I've got two different views on it over the past few days:
COMPLETE STOCK means flashing ASUS' original stock firmware, which completely wipes out everything on your tablet (including your nandroid backups) and CWM and takes you back to a fully stock tablet (except it will still have unlocked bootloader). From here, if you want to install ROM's like CleanROM or Hydro you have to re-flash CWM each time, then flash the appropriate ROM.
MODIFIED STOCK would be making a nandroid backup of your stock settings as soon as you flash the stock ROM, install CWM, then back it up and you can revert to it accordingly. I don't know if this would break things when you tried to flash Clean/Hydro and so maybe someone can clarify.
I wanted to try both hydro and cleanrom so I spent many hours yesterday flashing between stock/modified stock. Its kind of a pain, but all part of the learning process.
And one thing I want to note both for myself and for anyone else: if you flash stock without removing CWM it'll give you the broken bootloader logo (android on his back w/ exclamation point), and my solution has just been to do a 'wipe data' from the fastboot menu and the stock will work fine. What I mean by this is I've done this at least three times, where I flash STOCK from within CWM and when I try to boot into recovery, I'll get that android. That's because STOCK completely erases everything including CWM so in order to restore the normal operating procedure, you just need to 'wipe data' from within the tablet.
Hope my understanding of these situations is correct, if not anyone can feel free to correct me
People like to experiment with their tablet, they get easily bored with the same thing.
So they go back to stock and flash another rom like Hydro which is stock based because when you flash CM or AOKP it won't let you just flash to Hydro.

NOT TRUE!
It should be noted that TWRP is now more functional than CWM. TWRP can now flash stock ROMs just fine. It can now restore complete nandroids, including /boot, and it can now flash from and store to the external SD card. It was just recently updated for this, which is why all the information until now has said to use CWM to flash the stock ROM. So, go ahead and use TWRP. It's perfect now.
Hey im tryinna OTA update my One S its at Android Version 4.0.4 Sense 4.1 and i have an OTA ive had it for a while now. How could i update it and keep my root? Or if i install a higher version custom rom will it brick my phone?

not sure what you mean with your last sentence... but:
in my case the ota deleted my root. but I also recommend to do a factory reset after updating to 4.1 sense 4+, just to be sure that you have a clean jb rom (do titanium backups of your apps you wanna keep).
but you have to be on stock recovery if you want to apply the ota.
after your update you can root your phone again.
applying the ota wont have any effect on flashing a higher / newer custom rom.
you only have to be unlocked and on custom recovery. but you alawys have to flash the boot.img of the custom rom after flashing the custom rom zip.

the rom you want to flash doesnt care about your previous rom, because you wiped your previous rom.
so it really doesnt matter which rom you have before if you want to flash a new rom.
its like.. you have installed windows xp, then format your hdd and install windows 7, windows 7 doesnt take a --- about the old os
recovery and rom are two different parts.
you can stock recovery and custom rom, you can have custom recovery and custom rom, you can have stock recovery and stock rom.. blaaa
