Not possible you may get same rom from branded /providers roms posts /
2) what is the best way flashing the first time?
Follow the instructions
Decide what rom you want and read instructions before flashing .
a) flash cf-root then backup /enf then backup my rom
If you have cf root and CWM flashed then you can use CWM to backup
b) flash SiyahKernel thet will auto backup /enf then backup my rom
If the instructions say they do then they will .But i dont recall that kernel backing up the rom .

[Q] How to backup S2 Stock Rom

I want to backup my stock ROm does anyone know how to? I heard there something called clockwork, could someone explain further and have you tried it working?
One try the branded rom posts for your phone .
BUT you say its STOCK rom no need to backup stock roms just download a stock rom .
Clockwork Mod is a tool that installs custom roms and also can back up your current rom .
CWM is found here with root .
Root + CWM .

[Q] Backup kernel?

Hi everyone.
I was wondering if there's a way to backup my kernel. (before root)
I want to change the rom I'm using, but due to legal issues I need to be able to revert back to the rom that's installed on my phone now...
I know I can backup through recovery but I need to root my phone first and I cant find this specific kernel so I can go back to it if needed.
So is there a way I can backup my kernel?
Or if anyone knows where I can get this kernel:
I9100JHKF2 ?
Thanks!
You need to download the stock kernel used by your rom, then reflash it when you need a complete stock firmware. I think there's no way o backup kernel without rooting your phone. Flashing with odin increase your binary flash count , flashing inside cwm doesn't not
Why would you want to backup a kernel ???
Firmware yes kernel no.
kernel is only a small part of the firmware and of itself is no use to return a phone to stock .

What do you really mean? from where are you accessing and what?
Why you want extract...? for removing any specific app?
If you have a CWM back up of earlier ROM, you can use Titanium Backup Pro for individual apps installation for installing from your earlier ROM....
I just wanted to do it in case I would like to back up to original state before rooting and flashing CM7.

Sorry to say you cant backup your current ROM till you root your phone...
Use checkfus to download original firmware .

If you use CWM you do not back up original as it has cwm and root kernel ,

Ok, I have back up my phone just after root so I have possibilty to back my stock T-mobile brand firmware but with root.

[Q] Noob Question Plz Answer

Hi ,

you can backup/restore both stock/ custom roms, the default will restore the whole backup replcaing the existing one, you can make advanced restore to restore specific backup.
well i restore many times if iam not happy wiv the custum rom so yes u can restore back but hav a proper backup and don wipe the whole phone as the backup goes off sometimes.

Yea you can restore your stock rom any time with Cwm recovery. As long as you have cwm recovery in your new custom rom you can acess your backups. So be sure you flash cwm recovery on your custom rom btw most of rom's come with cwm so you don't have to worry if not you can flash cwm recovery from odin too. Just search on google about cwm touch
Hope it helped you.
Thanks me i my words are helpfull.
Thanks You All cuz im not happy with this rom i wanted to go back..thanks again

As far as my expereriance, after restoring a ROM form your backup it is always a good idea to wipe Cache and dalvik cache befor rebooting. (not the factory reset..that will wipe your applications this you do before restoring only)
how will you restore to stock via CWM if CWM is via a rooted kernel .
It will be a non stock kernel .

I think here everybody meant by "Stock" is the first ROM which was there in the phone..no matter its rooted with a custom kernel.....

But its not original and voids warranty if restored was my point .
Far easier to grab a download of the original rom .
OP did say stock rom and not custom rom so the answer is as always not via CWM its no longer a stock rom once rooted .
