Root with CF-Root in stock recovery + Back up your existing kernel
Full Un-CF-Root and Restore your previous kernel
No need to a PC, no Odin, no Yellow Triangle or counter
Only one file flashed in stock recovery
Credits to Chainfire: http://www.chainfire.eu/
If there is one popular root method, it is for sure the CF-Root kernel one.
So, do not miss the original CF-Root thread here: http://forum.xda-developers.com/showthread.php?t=1103399
Advantages of CF-Root kernel are:
Keep a stock based kernel
Add Root with Chainfire SuperSU
Get insecure kernel for developers (Root acces for ADB in recovery)
Get permanent CWM5 and Chainfire CWMManager application
Get customboot.sh support

Original releases need to be flashed in odin, so you need a PC.
After flashing in odin, you get a Yellow Triangle and increase your custom flash counter. You need a special application called Yellow Triangle to reset these.
If you end up with a bootloop after flash (this can happen if you flash the wrong kernel) or you want to change your mind, you have to look for your previous kernel to flash it back
Unrooting needs you to flash a full ROM in odin, simply flashing previous kernel will not remove root.
In this thread, I got rid of these issues, putting the CF-Root kernel in a zip that can be flashed directly as an update in stock recovery.
The CF-Root files included here will backup your existing kernel to external sdcard (Kernel_Backup.img)
Later, you can restore your Kernel_Backup.img and fully unroot using the attached CF-Unroot file
CF-Root + Backup existing kernel files:
- Download the CF-Root zip file corresponding to your Kernel.
- Put the CF-Root zip file on your External SD (needed for stock recovery).
- Boot into stock recovery (volume up+home+power), and select "apply update from external storage".
- Select the CF-Root zip file from external SD
- It will backup your current kernel to Kernel_Backup.img file on the external SD and apply CF-Root for your kernel

CF-Unroot + Restores your Backup Kernel from SD Card
To completely remove CF-Root without having to flash a full ROM in odin, use the attached CF-Unroot.zip file
It will restore your Kernel_Backup.img file from external SD and remove all root files and CWM Manager application
It is unsigned as you are supposed to only use it on CF-Root Kernel when you have a Kernel_Backup.img made with previous method
FAQ / Fix for common issues
After flashing CF-Root kernel, you end up with no root access:
This is not caused by my script, but can happen even under odin when you flash many kernels
If it happens to you, just run the attached CF-Root-Fix.zip attached here. It will put superuser and cwmmanager application in /system
You used my CF-Unroot.zip file without the Kernel_Backup.img file in ext-sd
You should have read the instructions!
But do not worry, the script should now abort and nothing is done
You can use the CF-Unroot script to flash any kernel over CF-Root kernel
Just extract the zImage or boot.img file from the kernel you want to flash and rename it to Kernel_Backup.img
It can be useful to quickly try some kernels. Keep in mind that mobile odin can also directly flash zImage files.

No, this part is easy. Can be helpful for many people not having PC, or when you're on the road, flash a ROM and want a root...
I am looking to make CWM permanent... but this moves me to custom kernels, while all my guides were about keeping stock kernel
Also, it will need a kernel build for each kernel version, no other way till now. So people will need to rely on me to build each kernel. Not sure I have the time for such a support.
Looking to release only a few kernels maybe.

Yeah CF-Root is most popular because it was for long the only reliable method, but since Rachmat3 came with the injection and you polished it to current state of art perfection makes it little bit obsolete Why to bother with insecure kernel (and till now with counter increase and yellow triangle [not anymore as sorted by you again ]) when you can do it in such easy and noob proof way?

Insecure kernel is useful for dev purposes and also to recover phone in some circumstances
CF-Root also comes with fixed cwm and a cwm manager, useful for dev and crazy flashers.
Also, i forget to mention customboot.sh and init.d support
So, depends on each one and its needs

With these zip, rooting an S2 can be done at the age of 5.
Also, for the cf-unroot, you can put any zImage file, rename it to Kernel_Backup.img and it will flash your new kernel

Hey Guys!
I got 2 questions about root and flashing mods via CWM.
First is:
I rooted my I9100 with CF-Root (thanks for this Chainfire!) and reflashed the Stock Kernel to get rid of the yellow triangle.
Root Checker etc. still says I'm root so do I have to flash back the cfr-Kernel or isn't this necessary anymore?
Secondly:
If I flash a mod (e.g. circle battery mod) and want to flash another one (e.g. crt-effect) and both will modify the framework-res.apk, will the second mod overwrite the first one?
Or will I have both mods active after that?
Thanks in advance.
Kc
1. if you followed instructions and flashed the zimage after using the stock kernal no. other wise flash the zimage that you unpacked.
2. As along as they are different mods, it will not overwrite your previous modifications.
Thank you for answering.
But I was still root after reflashing the stock kernel.
Are there any benefits I will miss when I don't flash the zImage through CWM?
because I still could do everything I wanted to, for example getting root access and browse system folders.
What other benefits will the cf-root kernel give me?
2. Sounds good, thank you =)
flashing the zimage will replace certain links that were over written when the stock rom was flashed.
Not all commands will work properly because the are no command links to certain files.
can you get to CWM recovery?

You just lost cwm recovery by flashing the stock kernel, so good luck flashing any mods or installing roms.
So after reflashing the stock kernel I'm still able to reflash the cf-root kernel via CWM but I will not be able to flash any mods?
Seems a little bit strange for me...
you just need to reflash CF-Root zImage with CWM to have a CWM recovery.
---------- Post added at 03:15 PM ---------- Previous post was at 03:10 PM ----------
for flashing mods and other stuff you need to have CWM RECOVERY!
So without CF-Root I will land in Samsung/Android Recovery Mode instead of CWM Recovery?
Yes that's the point of the cf-root kernel, it adds root and cwm recovery.
Just flash the CF-Root kernel and jig the triangle.That way youll have full access to everything you want to do.Easy.Also might come in handy if you need to clear the counter for warranty purposes.
Yeah I just reflashed cf through cwm and will jig the counter to 0 if I find time to build a jig
Hi,
Firstly I will mention I'm a noob. I hgavent installed a modified ROM before, I currently have the latest 2.3.5 KJ2 firmware which I flashed using ODIN.
I want to installed a modified ROM mainly to get a digitial battery display in percent on my notification bar. However it appears all these modified ROMS require flashing through your SD card. The problem is I dont have an SD card. Is there a way to do this through USB only (i.e. Odin)?
Also what ROM and kernel would best suit my simple needs?

save the rom of your choosing on your phones usb storage...there you can flash it easily...so download rom and you will find it if you go in my files then search the folder download and it should be there ready for you in a zip file..
just follow the instructions at the main page of the rom thread that you want to flash and you should be fine..
first though if you are not already make sure you flash a cf root kernel so you get rooted and then go ahead and flash a rom....once you have cf on then you should have cwm were you can flash your rom through there...
http://forum.xda-developers.com/showthread.php?t=1103399
follow the guide in that link (im sure you have done but its late here so sorry) and then will see you have cwm and then flash your rom of your choosing
I'm rooted but I rooted the old way --> flashed an insecure kernel, downloaded this program called S2 root and rooted via USB, then flashed the original kernel back. It appears that by doing it this way, I don't have clockworkmod recovery..
Should I always flash using the way you said?
Ok.. so let me go through the process..
1) Get a CF root Kernel which will allow me to have cwm. Question: Does the kernel version always have to match the 'ROM' version? When I updated to KJ2 I see that under phone info the 'Baseband Version' reads I9100XXKI4. Does baseband mean ROM, i.e. I have KI4 ROM but KJ2 kernel?
2) Flash following instructions from the modified ROM. I can simply store the rom on my phones memory and flash from there. Do I have to do anything after this? e.g. wouldnt I have to flash another kernel from that modified ROM, and in doing so would I lose my root and cwm? How important it for ROMS to match kernels?
Also, when I install the CF root kernel I get the yellow triangle on boot right.. I read the method on your link to remove it but it seems complicated. What is he actually doing to remove the triangle? Is he flashing back the original kernel?
The method he mentioned is the easiest way to flash a custom kernel, without having the yellow triangle.
The kernel doesn't have to match the ROM version. A custom kernel, e.g. like hardcore's speedmod (can be found in the original android section) installs root and CWM automatically.
Flash the custom kernel with Odin. The yellow triangle should appear after that. But CWM should be available and you're rooted now.
Reflash the original Kernel with CWM to remove the yellow triangle.
But wouldn't reflashing the original kernel using cwm defeat the purpose of flashing the custom kernel? Also do I use 'flash an update' or :?'flash a kernel's what's the main difference?

Any stock kernel is flashed through ODIN after rooting to get rid of yellow triangle. Afterwards, to flash any kernel of your choice, use DarkyROM tool.
https://market.android.com/details?id=com.ficeto.darkyrom&hl=en
Just copy the kernel tar file in to your usb storage and you can flash the kernel within phone using darkyrom tool (no need of pc). Also this method won't give you back the yellow triangle again.
And to be safe, it's a wise idea to buy an USB jig to reset your binary counter.
Thanks for your help Droid. Interesting I noticed that I did not get the yellow triangle after flashing siyah kernel over cwm. Original kernel before that was the stock one modified as per crikelos instructions to get the speedmod.. is that normal?
Ohh I don't get the binary counter thing. Why do I need to reset it? And how and why can a USB jig do this? A link would help. Thanks!

Galaxy S2 i9100.
Bad chip.
Bad Firmware: Stock 4.0.4 with (Stock) Kernel XWLPT.
Rooted with S2Root+Using SuperSU.
Searched forums, only similar thread is for Galaxy Tab. I'm assuming it's not relevant enough for me to follow it directly.
If possible, explain it like I'm 5:
What is the safest way to install a custom ROM? (Ideally, I want to install CM9 and later CM10 when it is more stable). I've seen people saying to flash Siyah kernel first, then do whatever afterwards. How can I do this? Almost a complete noob here, what buttons do I press in Odin and what procedure do I follow to flash a safe kernel then a custom ROM.
NB: USB is a little buggy, on-device flashing preferred for that reason.

Yes,, you need to flash a custom kernel.
1. First post your full ROM details
2. Can you confirm that you have ROOT access?
3. If your USB is buggy, you still flash Siyah kernel using mobile Odin, or the temporary CWM recovery. Root access is needed.
Thanks for the really fast reply.

1. Stock 4.0.4 from samsung; Kernel version 3.0.15-I9100XWLPT-CL941023
2. 100% have root access. Running Droidwall (which is working) among other things
3. I'm unsure if it's the phone, USB port or drivers which are buggy.
Is it possible to get a definitive procedure to flashing Siyah with mobile Odin? (presuming it's safe to do so). After that, is it safe to just flash the full CM9 ROM with CWM?
The safest way to avoid the emmc bug is to flash a custom kernel. Like siyah or dorimanx. If you have root access, and CWM, you can install one of them. Do you have CWM? well then follow these steps.
-Download a custom kernel. Eg the .ZIP file of the latest version of siyah kernel for S2 from gokhanmoral's site.
-Store it in your internal SD card on your phone.
-Boot into recovery. ( Vol-up + Home + Power button )
-Go to: install zip from SD -> install zip from internal SD
-select the kernel's zip file
-select 'yes'
Let the phone reboot once your done. You should have a custom kernel and no chance of the emmc bug bricking your phone.
The reason I suggest using CWM rather than Odin, is incase you have a faulty usb port, that might pose a problem while installing via Odin.
Hope this helps.

I have root access but no CWM. When I originally rooted the phone the sole reason was for droidwall.
Is it safe to install CWM and flash a custom kernel as long as I don't do any data wipes?
Can I install a custom kernel and have the phone as is (without noticeable differences) until I flash a custom ROM?
What happens to SuperSU and it's settings when I flash a custom kernel (and will I still have root access)?
Finally, if anything screws up what is the recovery procedure? I don't have a copy of this kernel/firmware as I installed it as an OTA update.

You can make a nandroid backup with cwm. That will create an image of the current state of your phone to restore incase necessary. Just make sure u have a custom kernel and follow steps mentioned in the guides on this site and you shouldn't need to worry

Thanks for all the help so far.
I've installed Mobile Odin (v3.35)
I've installed FlashKernel (v2), there was a v1 higher up the page but I'm going to assume that v2 has some bug fixes or other updates (please correct me if I should be using FlashKernel-I9100-v1 rather than v2.
Now, I'm not sure where to go: Should I install CWM or flash straight to Siyah kernel. CWM seems safer since I can do a backup and hopefully have some access if anything goes wrong.
How do I flash CWM with Mobile Odin? Which flash (mode? partition? not sure about terminology here) do I choose (Kernel, ..., etc) and probably importantly: which version of CWM should I be using? I've seen many threads talking about CWM4/5/6. Are they simply updated versions? designed for different kernels/android versions? Are there any specific versions which try to mitigate the superbrick bug?

Flash Siyah kernel straight using mobile Odin. It comes with a permanent CWM recovery too.
Todays almost all kenels are safe
so resure yourself
And be careful, when you flash rom in recoverymod
if. battery is off when flash rom, your device have hard brick
so you must have change your main board

Siyah kernel flashed and working perfectly. Didn't realise how instant it would be. Thanks again to everyone, this community is friendly and helpful.
I'm just wondering as I'm in the same boat as the OP was once in.
When it comes to choosing the Kernel does it matter if its JB based or ICS because I'm on the stock ICS rom.

You don't have root access, right? Flash a custom kernel with Odin (like Siyah), but make sure it's compatible with your firmware. So if you're flashing Siyah, flash the version (v4 and/or v5 is what I thought) that's meant for ICS, otherwise your phone won't work.
Sent from the Matrix
Actually I used another method that allowed me to gain root access, but I'm on stock kernel and rom. I kind of feel safer when flashing a kernel and rom from recovery.
So say I use Siyah ICS for my Stock ICS rom, If I wanted to flash a JB rom like the one leaked from samsung would I need to also flash the Siyah kernel for JB too?
I have I9100T as well and 4.0.4 on it, what do I do? Will Siyah work for me?
I am about to install the international S2 JB ROM, and want root. The solution I have seen so far is the Siyah Kernel (6.0b4/5).
My question is this: If that kernal installs root, will I lose root if I change back to the official kernel that is inside the Firmware download (zImage)? What I might need is the CF-Root kernel, but I can't find it for JB (yet). Is it just a case of waiting for this?
I'm not familiar with ADB but am willing to teach myself, if this would help once I change to the siyah kernel (have looked at the quick root guides here: http://forum.xda-developers.com/showthread.php?t=1075278) but all the downloads are flagged by both Chrome and Avira if I do decide to continue past the chrome warning)

Thank you very much for your quick reply. I see now, the recovery seems to be part of/linked to the kernel. But I should still have superuser for use of titanium backup?
The only question I asked is: Do I keep root/busybox/cwm recovery
Lol of course you'll lose root and cwm, common sense. You will be flashing a new ROM package, new everything.
The only way to keep root (doesnt actually keeps, roots while flashing) is mobile odin.
I've found the answer, I do keep root, you were wrong.

Devils advocate here
Arent you still going to have to flash a custom kernel, without the emmc bug, which will (usually) come with su anyways?
I guess what im saying is, while this can give you root without increasing the binary counter, it will still leave you with a buggy stock kernel....
For me, from stock, i do the following:
1) Flash Philz kernel and recovery from stock recovery. (wont increase binary counter, and includes CWM recovery)
2) Reboot
3) Back up efs (important)
Then either stay on stock, reboot into recovery and flash Dorimanx 8.43 branch (with su included)
Or
reboot into recovery and flash custom ROM (usually with root)
And then update su (superuser or SuperSU (better))
Thats not exactly hard to do.

Thanks to reply
I created this thread for who wants only root (without flashing kernel, using odin and flashing custom rom)
I think it will not leave any bug (It's only copy files) and will not do anything to kernel
and your way is good but it's still replacing kernel ( duh )
