Any root file .
jje

surely it must be the root file which corresponds to your kernel?
if you can use either then why do all the different kernels?

Any body with a constructive comment.

ANY will work .
KE5 is your firmware but no root KE5 nearest KE7
End .
jje

ok, but why the need for all the different kernels KE1, KE2 etc etc.
Why not just have one generic one then if any will work?

In the same forum, look for the other thread on how to root from my specific operator ROM.
I gave the answer.
You must first flash an official firmware then flash your specific csc
Then you will be able to flash CF root corresponding to your new firmware.
Flashing official firmware, you could loose specific apps or widggets provided by your operator

[Q] What kernel to use to root?

Hi,
Planning to use this method to root
http://forum.xda-developers.com/showthread.php?t=1125414
BUT not sure what unsecure kernel I need.
I have done the *#1234# thing and it says:
PDA: 19100BUKE5
PHONE: 19100BUKE1
CSC: 19100VODKE2
Which one gives the right info? Phone, PDA or CSC?
Thanks.
No one has any idea?
How did y'all root your phones then?
Your phone is KE5 firmware .
jje
ok so I can flash any insecure kernel e.g. KE7 for example?
EDIT: also, if I use an unsecure KE7 kernel and then reflash a secure KE7 kernel, a. is this ok, and b. I will then have KE7 firmware I think?
Cheers.

To do it in tue good way :
It seems you have an operator firmware
First you must flash using Odin a samsung official firmware like (KE7 last KIES update for european people) to find the samsung offical firmware for your country, look in the official firmware and root thread of intratech.
Then You can flash the CF-Root kernel corresponding to your new firmware.
The yellow triangle is really nothing bad. Just meens you didn't use all offical samsung stuff ...
Edit : in Intratech thread, for choosing you firmware : find one with same csc as yours or a multi CSC firmware.
Or after flashing any firmware you want, re-flash with
ODIN, your CSC (present in Intratech thread)
in ODIN, use CSC BOX not PDA and don't touch anything else

Ok so I have the KF2 firmware for flashing.
It came with three files:
Phone_I9100XXKF2.tar
PDA_I9100XXKF2.tar
CSC_I9100XEUD1.tar.
I am on Vodafone UK. So I think I should replace the CSC .tar file with this one that I found:
CSC_I9100VODKE2.tar
This CSC .tar is the same one I have already: thus I should have no issues with connectivuty settings etc after flashing.
Is this correct?

That's correct.
Or you can just reflash after updating to kf2 your specific CSC using Odin and CSC box
CSC are specific from a region/country (keyboards langages ...) that's why you should use one specific to yours

Ok great stuff.
So: I use Odin to flash the firmware to KF2.
Then I can root it with the XXKF2 unsecure kernels etc.
Cool.

Nop, you should use Chainfire CF-Root kernel (kF2)
You will be directly rooted and will have CWM recovery mode.
His KF2 kernel is in his 3rd post i bolieve
But don't forget to download and flash your CSC with ODIN in the CSC box if you don't want to loose your specific country configuration.
You will find your CSC in the Intratech thread : official firmwares and how to root.
The how to ROOT from Intratech is older than the CF root from Chainfire.

[Q] Questions regarding stock kernel

Evening everyone,
First of all, yes, I am a noob and yes, I know there is a ton of information on this site. I've been reading basically non-stop for the past day and a half and though I've basically figured out everything I need to know (for now) I still have a few questions and need a bit of clarification. If this info is available elsewhere feel free to link and complain about me starting a new thread.
Just got my sII yesterday, info is:
Gingerbread 2.3.3
PDA: I9100MUGKG2
PHONE: I9100MUGKG2
CSC: I9100MBCKG2
Carrier: Virgin Mobile (Canada)
I'm planning on doing CF-Root -> VillainROM and I believe I understand all the steps for that. However, in an attempt to avoid completely voiding my warranty, I was hoping to find a stock kernel that I can flash in case of emergency. It seems as though there isn't one available for Virgin in North America yet, so what's the next best thing? Is KE7 compatible (I'm still a little confused as to whether I need to find a KG2 version or not)?.
One other question, can I root using CF-Root as my phone is now and use the XX_OXA_KG1-v4.1, or is it incompatible due to the fact that my phone is running KG2?
Thanks in advance.
I can't help you with your stock rom question, there's a thread in android dev that has all the stock roms.
To root, just flash the closest cf root kernel, the KG1 one should work ok. You are using one of the 2.3.3 kg2's and kg1 is 2.3.4. If you have any problems you could try the KF2 cf root kernel or one of the .3 kg2 kernels
Samsung are great at mixing around version numbers! We have about 3 diff kg2's!
Once you have flashed vr2.1 I would use the newest ninfetamine kernel (see my sig). It won't autoroot so you may need to use cf root to root.

Thanks for the reply. I hadn't actually heard of the ninfetamine kernel until you mentioned. It there a significant difference between jusing that and just sticking with CF and VillainROM?

I find them a lot faster than cf root with villainrom, its easy to try it out and you can always flash back.
Ninphetamine doesn't auto root so use cf root to root then flash it.

Right, thanks for the correction. That is what I meant, just used the wrong term. Am I right in saying that there is no stock firmware available for Virgin in North America yet, or am I just mission something? I've been frequenting the firmware thread, edit: (linked wrong thread) http://forum.xda-developers.com/showthread.php?t=1113928&highlight=canada in hopes of finding it, but nothing for KG2 in North America yet.

[Q] how easy is it to roll-back (un-root)?

Hi all,
A quick question on how easy to roll back (un-root) and put back the stock ROM?
My current ROM is stock Telstra ROM. (just bought the phone today)
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
Build Info : Jun 21
I know how to roll back a HTC Desire - by installing the RUU image from HTC or use the PB99IMG.zip install method to remove "root" and put back into std ROM.
I have yet to root my SGS2. Reason to un-root and go back to stock ROM is for warranty purposes. you never know what will happen (for example, my desire decides to dies on me yesterday, had to put back stock ROM to submit for warranty claim).
thank you in advance

Very easy basics are install stock rom removes root and use usb jig to clear custom rom counter .

if i do not install any custom rom, therefore, the usb jig is not required, right?

Nope. Jig is only required to clear the custom Rom counter, in case you have to claim warranty and return the phone to Samsung. And also to force the phone in Download mode, if something bad happens while flashing custom ROM etc.
hey cad,
Made any headway here?
I just bought an SGS2 from Telstra as well and I have a similar phone to yours.
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
I too would like to retain the stock kernel, firmware and csc.
If we root with an insecure kernel, how do we go back to stock kernel if it's not downloadable?
Could we just flash another kernel if we are making a warranty claim and hope they don't check?
I assume CSC is where all the Telstra crap is stored and once we get ROOT, we should be able to back this up out of \system

Usual is flash a relevant stock rom or older stock rom and update via Kies.

CSC is a file for network settings and does not contain any customized add ons from provider .

Custom Rom
Hi all I new to all this so could someone point me in the right direction...
1. I need a noob friendly guide to explain what rooting is.
2. How to root.
3 what is odin and all the tools required to root and flash custom firmware.
Video tutorials would be healpful. Im comming from a HTC HD2 but it feels like the explanations were easier to find.
Thanks in advance.

[Q] Firmware Update Queries

Hi,
Bought a GS 2 a couple of days back and its running the following firmware
Baseband : I9100DDKE4
Kernel: 2.6.35.7-I9100XWKF3-CL276555
BUILD NUMBER - XWKF3
Have a few queries regarding flashing firmware
1) Can i flash the KJ1 firmware from Intratech's official firmware list?
XWKJ1
Android 2.3.5
This package has: PDA: XWKJ1| Modem/phone: XXKI3| CSC: XEUKH2
Download: http://www.multiupload.com/QYQLC8KGJ8
XWKJ1 Stock Kernel: http://www.multiupload.com/3W4XXTHFSZ
Password: [email protected]

Click to collapse
2) The firmware mentioned above has only one file.
If the package only contains one .tar archive then it will have everything, pda+phone+csc, in the one file.
Click to expand...
Click to collapse
3) Since the above package only contains one file, updating to the above firmware would change the CSC. I'm from India. And hence i would lose the settings.
How should i proceed?
I am very much new to this. The above questions maybe / are silly, but would like to know how this works.
Many thanks in advance.
Yes using odin, you can always flash another csc after, I suggest you read the thread and understand the basics of flashing firmware, before you proceed, flash cf root using odin so you will be rooted and reboot into recovery or use cwm app that comes with cf root and do a backup, so if things go wrong you can go back into recovery and restore back.
You can find cf root in original dev section.

The firmware update contains a baseband for a different country. If I update using the above, would I lose my network/data connectivity?
Thanks,
Shray

So if i update to the package without flashing the original CSC back, would i still be able to access my mobile network and data?
In other words, does the CSC have any carrier settings? I own a unlocked the GS2
Any help on my query?
Yes will be able to access the internet.
I tried a firmware of different country and even after that my GPRS and general call and text were working fine.
Later i flashed Indian CSC.

The CSC contains some customizations, but responsible for your baseband/network and data connectivity is the Modem/Phone part.
As there are many other users of your region/country running on Intratech's ROM versions, this should work for you as well.
P.S.: I prefer Frankenstein versions, as you can combine them with any other Modem/Phone and/or CSC.
Just download the files you need/want to use, put them into the corresponding section in Odin and flash them at once to your phone.
Good luck !

[Q] Rooting stock XWLA4 kernel

Is there a way to root the XWLA4 official stock kernel without flashing another kernel?
I found some threads in the forum but i couldnt find a way without flashing.
My phone specs are:
android version : 2.3.6
Baseband v: I9100XXKI3
kernel v: [email protected] #2
build number: GNGERBREAD.XWLA4
it's easier to just download Odin program then a CF-Root kernal that matches or similar to the one you have, putting phone in download mode connecting your phone, select under pda the cf-root-XX***.tar file and flash. You can do it in 5min. (SEARCH THIS FORUM)
If you going want to be with the big boys you have to be bold.
Search the forums, but the above is as simple as 123.
If all faills (which it shouldn't unless you have a messed up infected computer with a faulty usb cable) then you can just start again and flash a whole new stock firmware + pit file - also information available here in the forum.
Ps. remember to back up before doing it.
There are other methods .
Zergrush etc .
But why root do you need root to run something ???

I need to root in order to uninstall some pre-installed apps that i never use (that's one out of many).
I just dont want to flash a kernel and i was hoping if there is a way exept the already known ones. I 've tryed them all but none worked.

True. Neither latest zergrush nor the given link for rooting ICS work. Are there any other methods out there to root the kernel despite flashing the CF kernel?
I have stock kernel, stock rom and rooted mobile, I just used a cwm.zip to get cwm then flashed a file containing su and root access
