Erm.. your firmware is a carrier branded firmware. There is no matching CF Root Kernel for your firmware. You have two options:

1. Flash any unbranded official firmware from this thread: http://xdaforums.com/showthread.php?t=1075278, and find the CF Root that matches the firmware (look at PDA) that you just flashed to root your phone. The instructions are clearly laid out in the OP; or

2. If you wish to remain at your current firmware, you could take the KE7 CF Root (I am just randomly picking one, don't really matter) and flash it, thereafter flash back your stock kernel that can be found here: http://xdaforums.com/showthread.php?t=1113928, the only thing with this is that you would lose CWM Recovery and some functionality of CWM application. However, root would still remain and no pesky yellow triangle. As for instructions, again, it's on the OP.

@Chainfire

Would it even be possible to add BLN Support to the kernel?

Thanks
[Galaxy S II Original Android Development] hkwildboy:
Sorry, this may sound like a stupid question....

When you said "push the zImage file to /sdcard", did you mean "copy and paste" the extracted zImage on to the sdcard using a card reader on my computer? Or is it necessary to use ADB to push?

Thanks.
[Galaxy S II Original Android Development] DaFileFather:
Push it or Copy it

doesn't matter

as long as it is on /sdcard

and has the name : zImage
[Galaxy S II Original Android Development] hkwildboy:
Cool, thanks for your information.
[Galaxy S II Original Android Development] elban:
It would be very cool, but AFAIK, cf-root is a stock kernel with modified initrd, so you should look for a custom (compiled from source) kernel to do that, like supercurio's.

EDIT: or if someone can write a module for the stock kernel it will probably work on cf's too.
[Galaxy S II Original Android Development] tygoger:
Just wanted to say thanks for the effort to make this CF Kernel! Works great on F2.

Hi Chainfire,

My SGS2 has:

can I root this with your method ?

If yes, I need to download the CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4.zip file, right ?

Computer doesn't recognise phone when connected via Odin in Debug mode

Hi,

Apologies if this problem seems over simplistic but I am trying to gain root access - I am at the Odin stage and when I connect my phone, Odin does not detect it.

I have Kies 2.0 installed and I have set to Debug mode.

Any idea what the problem is? When i connect it in this development mode a windows popup comes up saying that the device is 'not recognised'

The phone can connect to Kies when debug is not on- I have tried to update it through Kies 2.0 but it fails everytime (still on KWDD!), when Kies restarts my phone to install firmware it says 'try again later'.....

Are the problems linked?

Any help will be hugely appreciated!
[Galaxy S II Original Android Development] dinoc:
@Harry - usually I search the first page, this is the one which gets updated, do you want me to read 75 pages ?

If you knew the answer you could tell ...
[Galaxy S II Original Android Development] ogdobber:
re-install the drivers from kies (debug off) -its in menu options i believe

then to connect to odin put your phone in download mode. (turn off and press volume - , home, power)
[Galaxy S II Original Android Development] :
If you read one page back (just as i said) from where you posted there is the answer to what to do with I9100

BU

KE5 which belong to a version number, but BU should be about the branded part, so no need to read 75 pages, but a bit more then just the start posts could've given the answer.

The reason that i posted the answer is cause of forum rules of XDA and very much new users to a new area for them only ask while the answers are easy to find and mostly a dozen of times in a thread, besides that reading a bit more could give a lot of wisdom for the future ;) .
[Galaxy S II Original Android Development] hrking2000:
Hi,

Thanks for the quick reply!

I reinstalled drivers with Kies (MTP mode) and I had Odin open in background- I noticed Odin detected the phone then. I disconnected the phone so I could put the phone in debug mode (and reconnected, when phone was on- Odin detected it then) -when I booted up in download mode Odin does not detect it.

Any ideas?

Just to say that I already had root via your previous insecure kernel and had no issues. But with CF-Root applied, IPtables is broken again and consequently breaks Droidwall. This same issue existed with my previous SGS handsets using your previous CF-Root's.

As you mentioned in OP, the CWM Manager remains when changing kernel. Is there a quick way to remove the CWM Manager app?

see this thread for more info on hemdall (flashing on linux) for the sgs2:

http://xdaforums.com/showpost.php?p=13995677&postcount=5

specifically to this thread, do this on linux:

- download the binary on the link above and download the cf-root of your choice

- unpack cf-root until you get the "zImage" file

- put the phone in doanload mode (power on with volume down + home button)

- connect the phone to the pc

- run "./heimdall flash --kernel zImage"

- done!

I did what you said many times before initially posting on this thread 2 pages ago.

The whole 'what if I use odin when phone is on' was a hypothetical question as Odin (and my laptop) doesn't seem to detect the S2 when in download mode and so I was just asking as I could not think of any other scenario where my phone was being detected by Odin (won't be doing that again).

I feel that I am 'part 5' of your reply: 'now you can ask on the forum'....

Any ideas?
[Galaxy S II Original Android Development] CamoGeko:
Have you got the right USB drivers installed for your Galaxy S2? Sounds like that might be the issue, also double check that you have Odin v1.85.

Reinstalled drivers using Kies (and updated to SP1) however problem persists.... when I connect in download mode windows says ''one of the USB devices attached has malfunctioned...' and Odin still doesn't recognise anything attached (it is in debug mode and all other steps in OP have been taken)

May just be my laptop.... I will give it a go on a friend's laptop tomorrow to see if that works?

Please look back a few posts, or use forum search. Your question has been answered already.

Transmitted from a Galaxy far far away via XDA telepathy.
[Galaxy S II Original Android Development] CamoGeko:
Yeah, trying on your friends pc is a good idea. Still sound to me like your drivers are messed up. I would advise you to ditch kies completely and just find drivers for your windows separately. Uninstall kies, make sure you remove everything related to it plus the drivers. Once everything is clean, connect your Galaxy S2 to your pc again and windows should automatically install the right drivers.

ok before i try to root/debrand let be see if i have got this right

(i have a vodafone 2.6.35.7-I9100BUKE1-CL182896root@DELL105 #2)

using downloads of XWKE7 from:

http://xdaforums.com/show...ighlight=XWKE7

and

http://xdaforums.com/show....php?t=1103399

1) using Odin3 i flash the 520mb I9100XWKE7_I9100XXKE4_I9100XEUKD1.tar file

boot it up as now should be XEU KE7 unbranded

2) using Odin3 i flash the CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4.tar file

this will add cf-root and so i can install root tools

3) using Odin3 i flash the I9100XWKE7_Kernel.tar

this gets rid of the yellow warning sign but leaves me with root access

4) Start CWM Manager, select Flash Kernel, and select the zImage from CF-Root-SGS2_XW_XEU_KE7-v4.0-CWM4.tar

this gives me back cf-root and CWM4 but without the warning sign

can someone please confirm i have understood this correctly as it is a bit different from the HTC desire!

many thanks in advance

UPDATE: Rooted and successfully removed the yellow triangle, great great thanks. yet, another concern comes up, if there is any stock update coming, i suppose i would need to do the following?

Method1:

1) download latest stock firmware from samfirmware

2) put the whole firmware .tar and use CWM(don't know if it would work?) or Odin and flash it

3) i would lose root and i would have to wait for Chainfire to release the latest CF for my latest firmware

4) it happens Chainfire the great has released the CF and i used Odin again to flash and root it again

5) i am rooted but i have this annoying triangle and counting again

6) i would have to do the trick to remove the yellow triangle again

Method2

1) grab some stock roms who had extracted by some genius and added root and just flashed it using CWM(I believe?)

please correct me if my understanding is wrong, thanks guys

Hi Guys,

On another forum somebody found out that after flashing the CF-root kernel (KE2-v4.0) the benchmark score of Quadrant was actually lower that before the flashing. I can confirm this finding, after the flash, the score dropped with a ~400 points.

I am fully aware that Quadrant is not a good tool to determine the phone's performance but, since the structural drop indicates something has changed on the system, I am wondering what the root cause of this finding is. Maybe the root/CWM application keeps a process running on the background that consumes more memory that affects the Quadrant score?

Does anyone has similar findings on this matter?

[Q] CSC verification due to CSC reference in .tar file name

Dear all,

A quick check before I flash CF-Root-SGS2_XX_OXA_KF2-v4.0-CWM4.tar

My handset has this installed: stock XXKF2 XXKF2 OXXKE2

From what I understand the CF-Root is purly a kernel (untarred there is the zImage contained within).

The question

Why does the file CF-Root-SGS2_XX_OXA_KF2-v4.0-CWM4.tar have a reference to CSC OXA when it is purely a kernel?

I would like to check that the MultiCSC OXXKE2 I have installed won't be overwritten.
