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 .

Hello,
(1) I am confused between root and cf-root? What's the difference between them?
I'm talking about these threads.

(2)CF-root - "THIS IS NOT A ROM - it is only a modified kernel.". Will rooting (either root or cf-root) change my kernel version?
(3)Let say I installed/ flashed/ root/ cf-root (i don't know which is the right word) my SGS 2 phone, can I get back to my stock version including kernel version for warranty purpose? Using these steps to revert to stock (http://forum.xda-developers.com/showthread.php?t=1075278), right?
As far as I gleamed, you have to have the correct version of the rom installed before you root. So if you want to root with CF-Roots KE7 kernel package, you have to first install a KE7 Rom.
To get back to your stock version you have to get a hold of the correct carrier branded rom and flash it with Odin. Take a look here.
By the way, you can find out wich version you currently have by entering *#1234# in your dialer.
Anybody more knowledgable feel free to correct me.

Yes if you have kernel KE2 and flash CF Root KE7 its now KE7
(3)Let say I installed/ flashed/ root/ cf-root (i don't know which is the right word) my SGS 2 phone
Its root all the same do you need root ???
, can I get back to my stock version including kernel version for warranty purpose?
If you have a copy of your original branded firmware flashing that back and removing apps that require root and resetting custom binary rom counter to 0 should be enough . Or flash a stock Samsung firmware

I rooted my SGSII using CF-Root 3.7, re-flash stock do zImage in CWM etc to remove the warning
Now there is CF-Root 3.8 available. Is it important to update? Do I need to repeat the same cycle:
- ODIN flash cf-root
- CWM kernel flash of .zip file
- ODIN flash stock kernel
- CWM kernel flash of zImage
TIA

I do not think that all stock kernels and their CSC and MODEMs are available or even noted. I flashed a custom ROM and would like to get back to the unbranded Netherlands version (likely the same KE2 for Benelux) but its unlisted even on samfirmware.com
I should think that flashing any stock version for your region (EU/USA/ROW) would leave the warranty intact in so far as a Samsung repair centre won't care/tell the difference.

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 .

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.

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

Cut and Paste ..
Use Triangle Away to zero rom counter .
Remove any root stuff like CWM .
Flash stock rom or your original rom from stock rom thread .
