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.

I didn't any backup before flashing a new kernel :crying:, so what can I do now if I want my stock kernel back?? What's a NANDroid (I know that is a tool but how can I do it?) ? Is Titanium bkp easily?

I prefer wait for stock JB Rom and probaby I'll , but, can I already find some JB ROM?

I don't need to remove the kernel even unroot my cell, alright?
Thank you!!

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!!!
Since I want to flash the thalamus kernel on my Nexus S with JB, I have to be on a rom and given that no JB factory image is available yet I don't really get what I should do.
When the OTA came out I was on a deoxedex, zipaligned, etc. stock rom of ICS, so, in order to elude the error status 7 issue I flashed the 4.0.4 factory image from google and then flashed the OTA update.
If I want to flash a JB rom, do I have to re-flash an ICS rom? And if so, can it be a non-stock rom or I would get the error status 7 message again?
No. You just need to make sure you have a custom recovery, like CWM. I was on ICS and then flashed a JB ROM with no issues.

Well, factory images just came out so it's fine now.

Hi,
I have followed everything in this thread http://forum.xda-developers.com/showthread.php?t=1837863
I have backups nandroid ready and wasn't too sure, if I dont like this build then i could restore back to stock using CWM? or Odin.
I felt that I need to wait for reply to comfirm before flashing this cyanogenMOD 10.
Thanks!

IF my memory serves me right, with an unlocked bootloader, you can recover to a TW rom but I think its needs to either have the kernel built into it OR you need to somehow flash to a TW kernel. I say this because I think that if your kernel is still an AOSP one, then the device will not boot up.
some roms already come with a kernel for their rom so I think in most cases, with CWM 6.0.1.x, you could restore a TW nandroid.
If you want to restore a backup of a TouchWiz rom you have then just use the EZ Recovery app to flash the hybrid (CWM/Kexec) recovery...reboot to recovery and restore your nandroid. Simple process!
Once the Dev's building TW roms start using the non-kexec flashing method then you will be able to restore using the normal CWM recovery. Just like you said, you can also use ODIN to restore to stock but it's a pain because you have to root all over again. Just know you have a few options.
Ok thanks everyone!
So good
Fwiw... I've been switching back and forth between Synergy and CM for a couple days now (flashing multiple times) and cwm touch works for synergy but u need new cwm for CM10.
Hope this helps.
Question regarding going back to stock,
I installed CleanRom and feel like it's using more battery than stock bloated.
Can I use CWM recovery to go back to stock nandroid that I made?
So I followed the methods on this forum to install the ROM,
Root,
install CWM,
make nandroid backup
unlock bootloader,
flash Cleanrom
Can I use the nandroid that i made to go back to rooted stock rom? or do I have to go back completely?
You should be fine using the nandroid as long as you do a full wipe beforehand.... If you run into problems you'll just have to Odin back to stock.
Can I flash back to TW from the 2.3.3.0 recovery or would I need to revert back to the previous TWRP.

You come back to TW at your own risk. This where most bricks happen. Best practice is to Odin back to stock and then come back to TW. Luckily you survived CM so far but flashing back to TW could cause a problem. If you don't want to Odin first wipe all partitions till raw and give it a shot.
ok just to clarify....Say I was on Synergy then flashed CM 10.1 now I decided I wanted to come back to Synergy. I would need to Odin back to stock, then flash Synergy? I just couldn't flash Synergy from Cm 10.1? Is this true for CM10 as well? What about flashing my nandroid backup instead of Odin back to stock?
Thanks

you do take the risk anytime you flash anything. HOWEVER, i have SYNERGY, MIUI, and CM10.1 along with Liquid (4.2) on my phone. YOU will have problems with finding your files, as 4.2 will create the 0 folder, and it may look like you have lost files. TWRP 2.3.3 does an excellent job of finding back-ups, or just scroll to find the TWRP folder to find your backups.
Gallery also has been known to "lose" pictures. IMO, they are still there, just have to find them. i've actually opened gallery and had it be empty, but a quick close, and then re-open and they show up. Sort of like it has to find them.
YMMV, make backups of everything, and flash away! just know what chances you are setting yourself up for, and be prepared.
edit: AND... i'm not responsible for anything YOU do to your phone... yada yada yada...
just thought i had to throw that out as well...

so i can use 2.3.3 to flash between TW and CM right? the last time i went back to TW was when i was on 2.3.2.3 and they were say i had to revert back to the recovery before 2.3.2.3. and with that i never had problems flashing between both ROMs. i just want to know if i can flash between TW and CM with 2.3.3 and not revert back to old recoveries.

Stay on TWRP 2.3.3. I've been using TWRP 2.3.3 just fine while flashing multiple Beans JB TW builds. Not sure what issues others had but it works fine for me. Also, if you intend to install 4.2 AOSP in the future then you'll have to update TWRP again anyway if you downgraded it.

yes, you can use TWRP 2.3.3 to flash old backups made with any version TWRP. with no problems.
however, you can NOT flash old backups made with CWM. different system and will definitely NOT work.
:cyclops:
thank you very much guys! appreciate the input!
what is the proper way to flash between TW and CM (10.1) so I dont get stuck in roaming mode again?
Yea I am about to do this to correct me if I am wrong please but we are suppose to Odin back to 4.0.4 stock coming from 10.1 then up grade to stock JB from there

know that if you go the ODIN route, you will have to re-root and re-unlock your bootloader.
if you have the MOST up to date recover (CWM OR TWRP - I prefer TWRP 2.3.3) and you have a backup made of a TW ROM, and are on 10.1 currently, then just clear dalvic, cache, and restore your TW ROM.
however, if you do not have one, then would suggest factory reset and then clean install of TW.
there are always "chances" of issues, mainly the 0 folder, but i've been flashing back and forth between MIUI bV, Synergy, and CM10.1 and only problem i had was when my mobile network got switched, and i had to go back in and change to RUIM/SIM. and that was the only thing.
just know what you are doing and know where to go to get answers to help fix things that may go wrong.
and, "insert legal comments here"... no one is responsible for what YOU do to YOUR phone, except YOU.
:cyclops:
The only bad experiences I've had going from 4.2 to TW is when I only briefly installed 4.2 but didn't get data working. That left me with no data in TW. So I had to odin back to stock then re-root, unlock bootloader and flash.
will i be able to go from CM 10.1 to AOKP 4.2.1 without any issue?

I haven't had a problem going from one 4.2 AOSP rom to another. YMMV tho. Just flash a nandroid before you do it just in case.
