Rooted stock rom ICS 4.0.4 but...

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.

[Q] JB update and custom kernel

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?

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.
---------- Post added at 12:35 AM ---------- Previous post was at 12:33 AM ----------
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!!!

[Q] Restoring through CWM to stock

hi,i am using stock rom running 4.0.4,i had it rooted too and now i had two queries
1)Is rom manager compatible with Atrix 2??
im asking this because when i open it, it shows u need to install CWM recovery...but no option in that responds...not even intall cwm (1st option in menu)....so i installed CWM using atrix boot strapper app and now still rom manager is not detecting CWM..please help
2)after installing CWM, i had backup my present stock rom..so if i flash a new rom now will that CWM and back up still exist??(because we will wipe data which will remove everyhting right??)
for suppose if i flash jelly bean rom and if i dont like it...can i restore my previous stock rom without bricking my device??
thanks for u r help

1) Rom manager is not compatible with Atrix 2. I would not use it. Why do you need it anyway??
You can use Atrix Bootstrapper to go into CWM recovery . Rest can be done there. Or you can use Boot Menu Manager.
2)Of course! it will still be there! the backup is saved on your SD Card. So as long as you don't format your SD Card. It will be there.

Rom Manager does work with Atrix2. If you're on Stock ICS, you can install CWM on every boot, then flash the Bionic recovery through Rom Manager. That will allow you to use the 1 touch backup in RM, just hit backup rom and everything does what it's supposed to.
Here is the CWM on every boot for Stock ICS.

No, your Recovery will be wiped after you flash a new rom, but you can install it again and restore your ROM.
But when restoring a rom, make sure you ARE ON THE ROM you are restoring.
E.g. If you flash JB and want Stock ICS back with your backup. First flash the Stock ICS from RSD and then restore your backup from CWM on it.
Or Vice-Versa.
@41rw4lk, Thanks for rectifying that. I did not bother with Rom Manager much.

I don't think any recovery exist after flashing a new rom. We have a locked bootloader, so we can't replace the stock recovery.img, all of our recoveries hijack the boot process to work. CM10 and PA I believe have a built in recovery, and that's about as close as you'll get to having a recovery exist after flashing a rom.
As far as restoring from JB, I believe you can downgrade to ICS, but you'll have to look at the JB thread to be certain. I'm on AT&T so I haven't had an opportunity to try JB (officially). CM10 is based on JB, but for our phone with the locked bootloader, it's more of a pseudo experience and is based on our ICS framework.
As for bricking, there is always a chance to brick, that's part of the mod game, but if you read and pay attention to what you have and what you're doing, you'll be alright.

UNLESS you have AT&T phone you should be just fine with ref lashing the ICS.
YES. there is a big problem if you are not on a ROM you are restoring.

You need to use the CWM on every boot setup, the Atrix2Bootstrap alone won't do.

Yes. I will say though, if you're on an AT&T branded phone with AT&T firmware, do NOT try to flash the new JB FXZ. It doesn't matter who your carrier is, it matters what firmware your phone is using. So, if you're on AT&T then you need to make sure that the things you flash are for AT&T, or else you will brick and that will be then end of that.

MIUI (had battery issues, but I think they got it all worked out)
there's a few, you'll just have to look. Most of the time, if something is not meant for AT&T, the devs will post in the description that it isn't compatible. If you want stock ICS back at anytime, you can do yourself a favor and make a backup of your stock ICS all setup the way you like it, so you can restore if needed. If all else fails, there is an Official ICS FXZ that will get you back to stock ICS.

You're killing me smalls. You're on ICS already, you're not downgrading anything, nor can you downgrade ie. Gingerbread. There is no Official JB for AT&T, so that's not an issue. CM10 is a JB based rom built on an ICS frame, (for our phone at least), and again, you're not downgrading.
To make a back up, boot in to CWM or whatever recovery you're using (not stock), and click backup. You might hit up the noob thread to get an idea of the terminology and basics for our device. Not trying to be rude, but you're running yourself in circles. You got to walk before you can run.

[Q] Custom recovery and CWM Recovery-on-boot for stock ICS

I've looked all over this forum and I hope that I can get a definitive answer here. I don't feel like my use case is that unique but I'm going to be as specific as possible and hopefully get as concise and complete an answer as possible.
Until recently, I was running a custom GB-based ROM. When I was running GB, I used the Atrix 2 Bootstrapper and RAZR-CWM-Recovery-on-boot-J.Y.Daddy (or whatever it's called) to get CWM Recovery on boot and make backups and so on.
I ran the return to stock script from my GB ROM and am now running the stock ICS ROM that I got from the official OTA upgrade from AT&T. I've obviously rooted it.
I want to make a backup of my current stock rooted ROM with CWM Recovery. To my knowledge, the old bootstrapper method does not work on the official ICS OTA upgrade. I don't want to multi-boot with BMM, I just want a custom recovery so I can run CWM Recovery to backup/restore/possibly flash a new ROM.
I know that most of the new ROMs include their own custom backup, but that leaves me with no way to get back to the new stock ICS ROM (to my knowledge, I may be wrong).
If the simple solution is not possible and the only solution is to install Numa or Paranoid or the unofficial CM ROM, that's fine, I'd just like to know.
Thanks in advance.

My advice would be to just use BMM from the play store, edit the recovery.fstab as shown in that thread.. And make a backup with that.. Use tar format I think (if there's a choice - sorry I have not made a backup on this phone in a while).
That should be good to restore with other recoveries.. Plus you can uninstall BMM and don't need to multi-boot..
But, wait, I thought the old a2 bootstrapper worked fine on ics...?

I actually haven't tried it yet, that's just the general "feeling" I got from what I had read thus far. I was up super late last night fixing three or four soft bricks before I got my phone to a working state again and now I'm taking the cautious route. The bootstrapper doesn't count as a custom recovery, though, for the purposes of creating a backup with CWM Recovery, right? As in I'll still need to find a custom recovery to run a backup.
That is, of course, assuming I don't just use BMM to take my backup now. I suppose I had planned to go with a custom ROM eventually anyway, probably Numa, or maybe the CM ROM (if it gets a little more stable here pretty quickly, I suppose).
I'm pretty pleased with the stock ICS ROM over my old custom GB ROM (SCv6), which is why I'm now circumspect about trying out a new custom ROM without having a way to easily get back to where I am now (because I lost my backups the first time, like an idiot).
Thanks for the reply.

You can do two things:
1.Install BMM make a backup of your current system.Install the custom ROM you want.Restore whenever you feel like.
2.Install BMM.Edit recovery.fstb(don't go after the name you just have to edit some text).Leave your current system on system 1.Install any ROM you like on system 3 and/or above.No need to restore.Switch between your choice of system whenever you wish.

SGS4G Android 2.2 rec 3e. Do I have to flash kernel and modem before flashing custom?

Yep.. You take a backup, wipe cache,data and dalvik cache. You are ready to flash your custom rom.. But while changing kernels you gotta flash your stock rom+stock kernel then root then flash new kernel then the custom rom.

Appreciate. So I now will backup and wipe everything and then update it with kies mini. And then will ask more about custom stuff, am I doing right?
The problem about SGS4G is that it is WAY TOO MUCH information about it as well as kernels, mods, articles and you are lost because some of them conflicts with other.
P.S. I spent a week for going into Android stuff and Galaxy S.

The guide seems good enough but a bit more complicated that it should be. Anyway here are two tips or info for you. First, whatever you do, have Odin and Stock Firmware ready to flash coz when everything else fails, Odin to the rescue and also flash stock firmware (Rom+kernel) whenever you change kernel as changing kernels without doing so removes root access and you cant apply root update on a custom kernel unless it has pre root access. Second, you dont need any kind of manager to flash firmwares and updates. CWM is a replacement to all. But its all your choice.
