Root and flashing questions from a beginner - Galaxy S III Q&A, (US Carriers)

Hi all. I am very familiar to android but this will be the first device I root and flash. I'm with bell mobility. I've been doing a lot of reading here lately and want to root and for now keep stock rom. I want to try ktoon kernel as well but haven't made up my mind about that.
I have some questions I need help with before I take any of this on. I understand that in order to flash a custom kernel I need to use cwm and I'm comfortable rooting and installing cwm. I want to be able to go to complete stock if I need to. My question is about getting that back. If I flash cwm but want to go back to 3e recovery will this work by simply flashing the bell stock rom previously posted by adamlange? Also I understand the custom kernel has modified wifi and bt drivers. If I flash the stock rom will this flash the stock kernel back as well. If not how do I flash the stock kernel through Odin? Will this stock kernel contain the drivers I need for wifi and bt? What are the main benefits of custom kernels? Is there any way to flash the custom kernel through Odin if I don't want to install cwm without tripping the counter?
I thank everyone in advance for helping me.

[Q] Is it necessary to flash custom recovery if using stock rom

Hi,
I'm running already Android 2.2.2 update 10E and I'm going to root my phone.
I want to use the same stock ROM.
Is it necessary that I need to flash custom recovery.
Please help & sorry for NooB question.
If you only want to root your phone there's no need to install custom recovery.

however, if u want to overclock, install touchlag fix, etc, you need custom recovery.
Thanks a lot for your replies. It helped me a lot.

Where Download?

I'm sorry if this is a stupid question, but I need to install only a recovery, because a custom rom brings ROOT. I'll use ODIN, where I can find recoverys in tar format, because the one I have, is the site of ClockworkMod and is in zip.
Thanks to all.

why do you need a recovery if you are not going to install custom roms. You already have the stock recovery to whatever you are going to do

Lol, you must know that CWM is integrated into the kernel, so if you need CWM you must install a custom kernel(insecure kernel) having CWM, and all custom kernels are made to enable rooting, trying to push CWM into stock kernel(secure kernel) is pretty dangerous and you might brick your phone, and stock has its on recovery mode which you can use. Anyway before performing any wipe or factory reset check whether if you have super brick bug if you are running ICS 4.0.4, and stupid question or not try including more details about your phone.

Ok.
Before anything thanks.
I want to install a CUSTOM ROM, like cyanogem, slim bean, etc. So your idea is install a kernel, but I can install recovery and then custom rom, right?
And this insecure kernel, can you give me the link to download?
Thanks.
P.S. - My SII have Gingerbread 2.3.5. original, I don't have touch in nothing.

I suggest you to update your phone to official ICS before flashing an insecure kernel

[Q] Flashing back to dualboot original ROM and Custom using Siyah

Hi, I'm unsure of how to tackle this.
I've flashed my way from stock rom and lost the backup somehow. Therefore I intend to download the original firmware package from Sammobile or Kies. The thing is; I want to continue using my Custom firmware as primary ROM and have the original one as secondary ROM. This is hopefully possible through Siyah Kernel and tools. Although, I'm not sure if flashing the original ROM will tamper with my kernel. Is it safe to do it this way? Is it even possible? And what will happen if i get an OTA update after a successful flash of the original ROM?
It's important for me to dual boot, but the custom ROM I have doesn't have great image processing from the camera, so... I want the original as backup.
Thanks in advance.

Swap your own rom from secondrom utility's.
Than install the stock rom via Odin
And swap back your own custom rom to be the first rom.
Because you use a custom recovery you don't get any ota updates.
After flashing Install siyah Kernel back.

i9100 Rooted but no CWM

Hello everyone, greeting from Turkey!
First of all im a newbie for android rooting and romming etc. I ve always used stock roms since ive got this phone. Now Im running a I9100 (int.) with stock Turkish 4.1.2 (XXLS8) on it and i ve rooted it via superuser.zip with my stock recovery.
What i want to do is to install CWM and want to flash a RELIABLE and Long Battery life rom. Are there anyways for me to install a CWM without using odin (via stock recovery). And can you please suggest me a good rom for daily usage. (i want to use vanilla android btw [just like nexus]).
Thank you for your helps.
I don't know much about roms/kernels for the international version, but you will need to flash a stock kernel with cwm and then just choose a rom from your development thread and follow the instructions, don't forget making backups and reading a lot, you can start from flashing cyanogenmod.

As i said i dont know about international version kernels, but it should have a tag like "stock kernel" or something like that if its for stock, just install it and you will have cwm, if its not stock it wont be installed anyway.

You can flash a kernel for stock roms via stock recovery, you don't need to use odin, just read the instructions.

I see a lot of ROMS posted list kernels other than mine (NC2). Do I need to flash those kernels prior to flashing those roms or not?
Also, If I want to go back to a NC2 roms will I night to flash that kernel back?
I am confused, please lmk. Thanks!

No need to flash kernal.
But, If your developer of Rom said that custom Kernal is required then you should flash custom kernal....
For backing to stock rom you need SP TOOLS (Smart phone tool) & Scatter file.
Every custom Rom does have its own kernel included which works perfectly with it. You don't need to flash any kernel. Just if you want to change the kernel you can change it afterwards. If you want to go back to your rom you have had before, just backup your system folder with twrp for example recovery and then you can restore it back. Hope that helped.
