tl, dr: brand new SG S2. Want to get CF-Root v5 CWM5, CM9, Siyah kernel 3.
I've been reading a lot of threads here lately, but I'm still confused about some things.
I'm new to android, but not so new to most concepts mentioned as I'm a linux user.
So I have a brand new SG S2 and want to root it and install CM9 (ICS) in it.
But before that, ideally I'd like to backup my phone (rom + efs). But to do that I have to flash CF-root, which itself modifies the stock kernel. So I'll lose my stock kernel.
1) Any work around to this? In linux?
My understanding is that this will get me the yellow triangle. And on CF thread he explains how to get rid of it. But the problem is that I checked the stock kernel thread here and I don't see my firmware there.
(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)

My firmware is PDA: I9100BUKG2 and PHONE: I9100BUKG1.
Do I only need to care about the KG1/KG2 reference? And which one is more important the PDA or PHONE?
So for example would XWKG1 do the trick?
There is also the issue of CF-Root upgrade. For my phone only CF-Root v4.1-CWM4 is available (I have PDA *KG2 and PHONE *KG1).
2) So after I flash CF-Root v4.1-CWM4, get root, backup my phone with CWM and k-tool, can I upgrade to CF-Root v5? Or am I stuck to v4?

Other kernels
Replacing CF-Root with other kernels and vice-versa sometimes works, sometimes it doesn't. I don't have a list.
When going from CF-Root to another kernel, root will usually stay, while CWM will be lost (unless the other kernel also includes it), but there should not be issues. The CWM Manager app may remain, but probably won't do anything useful.

3) Does this means it's impossible to upgrade to CF-Root v5 or to use the Siyah kernel?
How can I solve this?
Sorry if this post is somewhat confusing, I'm a bit confused myself
Thanks for any help.
Pmed u dude
Mod or Die
1.) There are a few BUKG2 on samfirmware.com. Not sure which one your provider is though. Once you upgrade to ICS (CM9(, you can use the triangle away in the original development thread to remove the yellow triangle and reset counter (works only for ICS) so that is one option for you.
Regarding the kernel, go under settings, about phone and see what it says under kernel (KG1 or KG2).
2) Once you root and get CWM, you can just flash a different kernel with the updated CWM to get v5. You could also just install the siyah kernel from V4 as it comes with its own version of CWM.
3) You will be fine with flashing most kernels from CF-kernel. Most kernel for the i9100 in xda includes CWM or sometimes its own version of CWM.
I used zergrush exploit to root my gf her i9100 with 2.3.5. Used root explorer to grab efs directory.
Then i had root so i could use mobile odin. Now phone is on litening 4.0.3 ics rom probably still with gb bootloader.
No triangle yet
Gonna flash ics bootloader through odin and move to cm9 nightlies tomorrow.

The zergrush exploit requires
(1) make sure u have installed adb drivers for ur device

What exactly does this mean?
Do I need to install the SDK? Or do I only need the adb executable file? Or is there any SG S2 specific file that I need to download?
Thanks
EDIT: in linux it only requires setting up a udev rules file

Also went with the zergrush, and after that kTool to flash CF-root CWM kernel.
Hi.
I have on my Galaxy S2 the stock ICS 4.0.3 (XWLP7) with CF-root kernel 5.4. I would like now to upload the phone with ICS 4.0.4 (XWLPU). Can I do it now like always with Odin or should I do first something else with my phone (wipe etc.)?
Thanks in advice
You can do it either way, I prefer doing it via CWM recovery.
To avoid BrickBug flash latest Siyah Kernel first (v4.1.2) before you do any wipe operations.
Then do a full wipe and flash desired rom.

I agree but personally would format system as well prior to flashing.

dwnld the 4.0.4 firmware and flash the same using ODIN since ur upgrading from a stock rom to another one it will not be an issue, but after flashing 4.0.4 u have to re-root your phone, since stock XWLPU 4.0.4 will automatically unroot ur phone

You can just upgrade using Odin, no problem.
Note:
-once you upgrade to 4.0.4, then say goodbye to CF-ROOT kernel.
-Just flash a custom kernel like Siyah, speedmod, Dorimanx, Dream at once.
Why?
-Because stock ICS 4.0.4 kernel has a brick bug enabled on it.
-This bug is also present on all kernels based on stock 4.0.4 kernel. CF-ROOT and all insecure kernels fall into this category
What will happen?
-If after rooting your phone after upgrading to 4.0.4, and you wipe your phone or try ROM backup while running stock/stock based kernels then say goodbye to your phone.

Hi. Thanks for your answear. But I would like to know how should I do it, step by step. I have download it the Sizah kernel 4.12.
1. enter the CWM recovery mode and install the Siyah kernel (install ZIP from external card)
2. reboot the phone or?
3. enter CWM recovery mode again: hold down the volume up button,home button and power button.
4. in CWM recovery I have to choose the wipe data/factory reset
5. after wipe phone reboot
6. enter the Download mode and install the new ROM with Odin
Why should I install the siyah kernel? I still have the cf-root kernel (my phone is rooted).
After upload the new ICS 4.0.4 if I wanna root my phone, I should make the root with Siyah kernel via Odin or? Do you think the Siah kernel is better from CF-root kernel?
Thanks
I thought the brick bug has been taken care of in the latest CF kernels

that was not because of cf-root kernel's ma8 since they r tweaked stock kernel's with EMMC_cap (Brick Bug) removed , hence there would be no problem, as i have used one two days back to root a friends phone which was on stock 4.0.4 LPT firmware without any issues
the brick might be caused by the wrong CF-root being choosen like the one's marked with * that people might have dwnld'd without properly reading why it has been * rd.

after upgrading to 4.0.4, simply flash the .tar file of siyah kernel v4.1.2 ( not the .zip file) from odin, it will root ur stock 4.0.4 rom for u and install the latest CWM recovery for u

OK friend.
So you think is better that I update from rooted ICS 4.0.3 to ICS 4.0.4 with Odin without CWM recovery. It sounds good to me.
After update I should install the new Siyah kernel via Odin too. And then I can do the factory reset or?

I had the same feelings two until yesterday,
Two different guys, running Wanamlite LPU ICS 4.0.4 ROM with CF-ROOT kernel (the Rom's default kernel), hardbricked their phones after wiping data in recovery while trying to flash another ROM.

1. Stay away from ROM manager, CWM recovery is already bundled with Siyah kernel
2. You can safely do factory reset with Siyah.

Hi,
I use a Samsung Galaxy S2 GT-I9100, ICS 4.0.3, XWLP7, Siyah Kernel 4.1.1. I have some simple queries and need someone to advice on the same.
1) Since i am on Siyah Kernel 4.1.1, would i be able to upgrade my phone to JellyBean using KIES, when the update arrives?
2) I guess if i flash a stock kernel i would lose Root. Please correct me if i am wrong. Secondly, would it be possible to flash a stock kernel using CWM? If yes, please provide me the links to get a CWM flashable kernel.
3) I had taken a Nandroid backup after installing the Siyah kernel since it came with a new version of CWM. If i wish to restore the nandroid backup, how should i go about it?
Your valuable advice would be highly appreciated.
Thanks in advance.

1. You might need to flash a stock kernel to do the same
2. Flashing stock kernel will only remove the CWM recovery, you will still have ROOT access.
I don't know where you can find the stock kernel in CWM zip format but you can flash the normal .tar stock kernel using mobile Odin
3. You can restore your backup the same way you took it, ie via CWM recovery (under Backup and restore). nothing special!
However, you need to use the same version of CWM recovery to used to backup to restore.
Thanks a lot Jokesy!!!
As usual your answers are to the point.
I'm new to the xda forums, so please bear with my total lack of knowledge on the subject.
This is the first time I'm rooting a phone. I read on a guide here that I need to download odin and a zip file of a kernel. The guide mentioned that the last three characters of my phone's kernel must be identical to the kernel that I'm downloading.
The thing is, I can't find those last "three characters" to search for..
Here is all that is shown under "Kernel version":
3.0.15-1087786

The android version is 4.0.4 (Which I've updated to just recently) and I'm using a Samsung Galaxy SII GT-9100.
So the question is Which kernel should I use for rooting my phone?
You can try siyah or speedmod
Sent from my GT-I9100 using xda app-developers app
If you want a pure stock based kernel, use the PhilZ-CWM6 kernel. This kernel can be flashed in the stock recovery, so your flash counter doesn't get effected.
You can use Siyah which I recommend. It depends on whether you just want root for rooted apps or to install custom roms
I believe the thread you're talking about is using the insecure cf kernel.
However since you're on 4.0.4 it isn't advisable to use that kernel since you may be susceptible to the emmc brick bug which will render your phone useless.
What you can do is install one of the above mentioned custom kernels. If you have a particular Rom in mind that you want to install, mention it here so that somebody can recommend a compatible kernel.
Neither siyah nor dorimanx require a particular build ( last three letters you were talking about) they're compatible with any ICS kernel, I have no idea about PhilZ kernel so can't comment on that.
Just FYI, i believe the three letters you're looking for will be found in the build number tab of 'about phone' in settings.

I want to install the CM9 rom for the s2. (I think it's jellybean 4.1.1?)
My build number is IMM76D.JHLPC
Baseband version is I9100JHLPC
Cm9 is ICS mate..not JB (4.1.1) that's cm10.
If you want cm9 ( older but stable) you can use siyah 4.1.5, if cm10, you'll have to use siyah 5.0 or the latest dorimanx kernel.
In both cases your current firmware doesn't matter.
There are many threads on how to root and get cm9 or cm10. Search and you'll find em.

You can root using odin-or you can root using recovery.
With odin,thats relying on everything being ok between your phone,and your pc.
Using recovery means no need for pc,you are flashing a temporary cwm which enables you to install su/busybox.You then flash a custom kernel containing permanent cwm(and emmc cap erase disabled).

That's all you need mate. This kernel is declared safe by Chainfire but as any 4.0.4 kernel should not be used to wipe data because of possibility of emmc cap bug rendering your phone bricked. Root with this kernel but make sure to switch to custom safe one before attempting to wipe data.
Best of luck

Essentially flashing using a 4.04 firmware will brick the phone? or is it when I flash, it will be bad to flash using a 4.04 firmware? Sooo confused.
If anyone has the steps what I should do, please tell me. I am worried about bricking.
If I root the phone, when official JB comes out, will I be able to update?
any help guys? The thread isn't very clear what do I do if I have this kernal. Do I downgrade before rooting?
Insted of flashing that Cf root kernel with Odin or Cwm, flash Siyah 4.1.5.

I actually have the same HW version in my new SGS2 and I have checked with eMMC check (downloaded from Google Play) that my chip is safe from "brick bug" :laugh:
Now the question is: which kernel to choose, CF or Siyah ? I'm planning to use CyanogenMod 10 on this phone, does kernel version matter at all in this case ?
/edit:
ROM will be either original CM10 or one of the variants (like HellyBean for example)

If GotBrickbug app by CF said your chip is safe than it shouldn't matter what kernel you use. Safe hardware.
Personally I always prefer rooting with CF kernels that match my FW version. Then if you're still unsure about the chip... flash siyah, go to advanced (while still in recovery) > reboot recovery. Then wipe data with siyah kernel just to be on the safe side. I always keep siyah 3.5.2 (the first transisiontl ics/jb kernel) for those purposes. CM10 built in kernels are all considered safe so that's the last time you'll ever be worried about it.
Best of luck, man
Thank you very much, I ran emmc check and I have a sane chip.

Samsung releases firmware in various regions and with varied carriers. So I bet that till it is officially released it will take time but when it does you will get OTA if your are on 'STOCK' ROM. but if you move away to custom rom then you will have to update manually.

To revert back assuming you didn't do backup before, download 4.0.4 firmware for your region on sammobile and flash it using odin.. Then to upgrade it when official update are up just hit OTA, kies, or flash it via odin the same way like you flash 4.0.4..
If you don't have idea how to flash then google it, theres plenty much tutorials out there.. hope it helps
Ohhhhhh. I get it. Flash using CF, or CM 10, use triangle app to remove warning triangle and if I need to unroot, flash with 4.04 (my region) using odin? Sound pretty simple. Am I missing any steps?

Actually I get confused myself hehe, by "Flash using CF, or CM 10" you mean flash what? The rest are ok..
Well, let's put this simple, Flash the CF-Root for your phone then you're rooted now, if you want to flash custom rom such as cm10 then flash it (the cm10 zip file to be flashed on recovery mode and don't forget to read the cm10 instruction before & after flashing), if you want to get rid of the triangle then do it with triangle away, finally to unroot and revert to stock, just flash stock firmware via odin..
Hi everyone! I just rooted my phone and it was sooo easy.
Thank you so much. Your advice and help definitely made it much easier than I though.
