Flashing question

I am new to the Charge but not rooting and Android. I came from the DX so the way things are done in this thing are different. Here's my question:
I am currently rooted and running a rom with a custom kernel. If I use Odin to flash the official software, will I also need to replace the kernel separately or will flashing the official software also restore the original kernel?

You will not need to replace anything, the Odin package is all in one. It will put you back to bare stock which means ROM, kernel, recovery, modem, you name it.
If you wouldn't mind helping could you link me to a rooting guide on a DX? Some general tips on rooting it would be very appreciated. My dad has one and I'd like to root/ROM it for him but i don't feel like studying up >_< Thanks!

Odin will replace everything, including your kernel.

Thanks for the response. I got confused because I saw posts saying that some kernels were interchangeable but I didn't know if they meant that you would have to flash the kernel after you flash the rom or if you just flash a new rom and the kernel remains. Appreciate the response.

You have to flash kernal only on cmw versions and not all of them read the pre requisites it will tell you if the cwm version either do not or do.have a kernal included for example humble 5 cwm version I.believe u.have to flash a kernal prior to rebooting or stock recovery will over write cwm happened to me and learned my.lesson the hard way !!!

Okay...so flashing the stock file will also get rid of CWM, right?

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.

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] doubt

Why do i have to reflash stock rom if i am moving from a cyanogen mod rom to another custom rom(like fitdroid,janas etc)
And does that mean i have to re root the newly installed syock rom and re-install cmw?

Who said to reflash stock rom every time?
And NO you dont need to flash cwm every time, it will be always there until unless you flash a stock firmware.

Btw with a custom rom your device gets rooted automatically

If you flash a full stock rom then you need cwm/amon-ra for flashing custom rom...
Rooting is optional...

thanks guys
Btw,i think i read somewhere that you should be on stock gingerbread rom before installing stock based roms

Hi,
I have similar question. I have installed Creed rom 3.5 on my Fit. I would like to try JoyOS from here:
HTML:
http://forum.xda-developers.com/showthread.php?t=1704120
I think I know how to use CWM, based on instructions posted in that thread, but in there it says rom is: based on Cyanogenmod 7.2.0-RC1 1.2 by tj_style.
I know that CreeD rom is based on stock gingerbread, and in his neewb instructions it said I need to upgrade my phone from Froyo to GB first.
Now, I also have same doubt - do that I need to have Cyanogenmod 7.2.0-RC1 1.2 by tj_style installed on my phone prior to installing JoyOS. I'm pretty sure I do not (I can not even find thread for this rom), but I would like just confirmation, since I'm little scared that I could brick my phone.
Regards,
Petar

Bricking a g-fit is not easy, believe me
Since you are on creed's, you probably have cwm installed...
So you just need to flash the desired custom rom of your choice (in the same way as you installed creeds) and you are done...

Thanks (I pressed it already )
Also, In case someone else might come up to same question, I realized that you also need to use “mounts and storage”>”format /system” in case you are transfering from stock rom to cyanogen for the first time. best would be to follow youtube tutorial about it.

[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??

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.

when i restore to stock fom JB, it means downgrading the firmware right??
so will there be a chance of bricking or is it same to restore anytime from any version??

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.

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.
