Well its still 2.3.5 so I guess you can use the nearest kernel. I would advise to do a backup beforehand just in case.

If you're on 2.3.5 then you need the XXKF4, if not use the other one.

I do not know, if any of the existing CF-Root kernels will work ...

... but there is an alternative method to root your phone by flashing an insecure kernel, running SuperOneClick and re-flashing the stock kernel.

Please stick to Intratech's description in the first post of his thread => http://xdaforums.com/showthread.php?t=1075278

But you will need the stock kernel (zImage file in a tar file) for your ROM!

Or wait till Chainfire will post the corresponding CF-Root kernel.

It's up to you.

Camera issue

Hello,

Sadly ife to report that at least the CF-Root-SGS2_XX_OXA_KI3-v4.1-CWM4 Kernel scres up teh camera.

It try to autofocus - which work but shortly after havin perfect fokus it blurs again.

its not possible to get a good scan of a busniness card

same issue on distance

However flashing back the stock kernel solved that so it really looks like its the kernel.

I dont know if other root kernels have the same issue but it looks like after reading same issues with that cam from other rooted phone users

Funny thing it happens only with full resolution. with less it works fine again.

problem here is that some apps like google googles or businesscard reader dont care about settings in the cam - they automatically try on full res so they dont work

Workaround would be use less than 8mp and a picture and scan it as a file

but this is not very satisfying and of course if you got an 8mp cam you wanna have those 8mp even i do not take regular pictures normaly :)

someone else having similar issues?

someone got a rom for 2.3.5 / cf-root with workign cam combination?

Ok, the nearest CF-Root kernel for your KG4 ROM (2.3.4) seems to be XX_OXA_KG5, as it is also Android 2.3.4.

That should work, but I have not tested it myself.

So, please make sure to have a backup before flashing.

Curious ...

... I would recommend to flash the latest available and stable ROM for your region (and provider) to your phone.

Please have a look at Intratech's thread (=> http://xdaforums.com/showthread.php?t=1075278) and read the first post !

I am running XWKI8 in the moment, and it is very good and stable.

XXKI4 seems to be good and stable as well.

The latest ROMs are XWKJ1 (Luxembourg) and JPKJ2 (Arabic/Iran).

If you flash a ROM from the Frankenstein section, you can combine it with any CSC file for your region/provider as you like.

So,

1. read

2. backup everything you do not want to lose

3. flash latest ROM

4. root your phone using the corresponding CF-Root kernel from Chainfire.

Good luck !

Dear All

I have got the SS II, with baseband is GDZKH5 and Kernel is "2.6.35.7 root@Dell151 #2" ang thelast row is: GINGERBREAD.DXKH6. So which CMW can I used to root for my SS GII? Or it has root already?

Please help

Thanks alot
[Galaxy S II Original Android Development] It_ler:
No, the "root" in your kernel info just says that the user, who compiled the kernel, was "root" on the device/computer named "Dell151".

The interesting part of your kernel version is missing.

It is the part before the text you posted above.

So, please post the complete string of your kernel info to get a proper answer.

Thanks !

EDIT:

DXKH6 ... hmm, I can not find this ROM.

Is it 2.3.4?

Then you can try CF-Root kernel for KH4.

But please remember to backup everything you do not want to lose before flashing.

Not sure if I should ask this here or wether the Q/A area is more suited, but anyway.

Updated my Galaxy S2 using kies to Android 2.3.4, baseband version I9100XXKI1, Kernel : CEKI2. From holland.

Used the CE-XENX KI2 CF-root to root it again, and it seems it stops the USB jig from resetting the counter and the yellow triangle, just like the KI3 does.

Was wondering if flashing the old boot loaders from Intratech through pda on Odin, work on the CF root as well.
[Galaxy S II Original Android Development] It_ler:
I have not tested it myself, but I can not see any reason for a problem.

Should work as described by Intratech ... even if you flashed a CF-Root kernel.

ok so i follow instructions on CF and then what how do i back up my pda, phone, kernel and csc in case something goes wrong
[Galaxy S II Original Android Development] It_ler:
If your phone is already rooted, you have several good backup options:

Nandroid and/or CWM Manager backup for complete system backup/recovery,

Titanium Backup app (from the Market) for your apps, etc.

If your phone is not rooted, there are only some and not as good options:

Google account synchronisation for contacts, calendar, mail, etc.,

some other apps from the Market, which do not need root (sometimes hidden in Antivirus apps and not very good),

KIES backup for contacts, calendar, messages and media,

or you have to connect your phone as mass storage to your PC and copy manually all the stuff you want to keep to the computer.

Very poor options without root ... that was the main reason for me to root my phone => to get a proper backup and recovery option.

I hope that Google will add a (better) system backup in pure Android OS ... sometime.

[Galaxy S II Original Android Development] luke222010:
Yellow Triangle - no more CWM

I've just flashed stock samsung XWKI4 firmware back onto my phone, and then flashed the chainfire KI4 root kernel over the top after putting the zimage at the root of my sd card.

However, when I then flash stock firmware over the top using chainfires instructions in the original post, CWM then stops working - and claims I need superuser for it to work - superuser is installed, and CWM is under the list of allowed applications, but it never boots.

Any ideas? It seems that the phone isnt rooted anymore.

I am guessing im doing something stupid or not reading properly! Can anyone help please?
[Galaxy S II Original Android Development] Rinoko72:
If i'm reading what you written correctly, when you "flash stock firmware over the top" you've gone back to stock, ie no root. You should have just flashed the stock kernel, to keep root and lose the yellow triangle.. :)

Try flashing agian the CF root kernel, then flash a stock KERNEL, if you want to get rid of the yellom triangle.. ;)
[Galaxy S II Original Android Development] It_ler:
Yes, it is correct that you should do the following:

1. Flash the ROM you want to have with Odin (XWKI4).

2. Flash the corresponding CF-Root kernel with Odin (XW_NEE_KI4).

3. Place zImage file of this CR-Root kernel to the root of your internal SD card.

4. Flash the stock kernel of your ROM with Odin (XWKI4).

5. Start CWM Manager app, choose to flash kernel and select the zImage file of the CF-Root kernel.

That should work fine.

Good luck!

To root you can use the CF Root KI2 kernel in post 6 of Chainfire's post. Follow the Odin instructions carefully, and you'll have no problems.

I bounce around between a few different ROMs. All of them are fabulous nowadays - stable, fast, good battery (in my experience, YMMV).

CheckROM Revolution works very well. It has good flexibility and a very useful app that lets you change themes, kernels, modems... nice for a mid-noob user. They also link to some useful noob-videos in post #3 of their thread.
