Hey guys basically is flashed my I9100 using ODIN with CF root kernel. It successfully rooted and I had superuser, CWM installed when I booted up my phone.
I only rooted to do a few things(like make phone sim free). Then I wanted to unroot it ( dont ask why (. I reflashed the kernel using my original kernel. But when I rebooted it the CWM and SUPERUSER app were still there and I still had superuser accessibility. So i removed superuser accessibility and deleted superuser but didn't delete CWM ( both were system apps).
Now I can't root my phone. When i flash using CF root kernel the phones restarts( and warning triangle shows ) but superuser isn't installed this time only CWM is but I can't use it since i don't have root properties. If i install superuser from market then it says su binary not found.

Thanks a lot mate it worked well, I am now re-rooted. BTW the yellow triangle appears in bootscreen when you have an insecure kernel installed.

Hey
I just flashed VillainRom KG3 with CWM and I lost root acces. I have the ninethephine kernel (or so)
In on holiday and forgot my usb cable. Is there a way to get root acces back so I can flash MIUI?
Thx

If you flashed CF-Root at least once, you have an app called CWM. Now, download and flash CF-Root from within CWM app's flash kernel functionality. I did it once and it works. CF-Root comes with root so you'll instantly be rooted. The same can be done with Rom Manager app too, I think but I haven't tried that.
Lol I just could flash the rom from CWM.

Once rooted and with CWM you can flash most custom roms via CWM including kernels .
A good tip is to leave the rom you flash on SD card you can then easily reflash in case of problems .

Another idea: install superuser and busybox from the market and see if you get your root back?
I don't know how you lost your root so these ideas may be crap, but you can always try, LOL...
Look for the CWM apk and download SU from Market, install both then reboot.
Guys,
Good morning.
I have a SGS2, I had rooted with ChainFire ROOT kernel (http://forum.xda-developers.com/showthread.php?t=1103399).
After the installation of the Kernel, I'd used an USB JIG (http://www.dealextreme.com/p/unbric...msung-t959-i9000-i897-m110s-i8700-i9100-93514) to remove the yellow triangle.
Then, I've installed the CheckROM 3.1.1 and the SiyahKernel 2.1.1...
Conclusion:
* I have ROOT
* I have the CWM if I press Volume Up+Home+Power
* I do not have the CWM app listed in applications.
Is this normal?
Am I doing something wrong?
Thank you in advance for your comments.
Regards!

CWM is an app not root .It is usually added to a custom rom .

OK, I get it.
But how I have another SGS2 (yes, I have my wife and mine)... And on mine which is running the same Custom ROM and Kernel... I do have the CWM app.
The only difference between hers and mine, is to remove the yellow triangle I used a USB JIG and on mine I flash a stock Kernel.
Thank you for sharing your knowledge.
to remove yellow triangle use cwm to install official kernel have the same number with the rom for example : jpkj ...etc ( zimage in sdcard)
than use cwm to install cf root sg2 ( extract zimage in sdcard)
------------------
i use siyah and speedmod but cwm5 have problem when launch so you can use cwm4 and try new kernel

Sorry, but I'm not asking how to root the phone.
I just want to know how can it be that I root the phone with the CF and I don't have the CWM app.
BTW, thank you for your reply... Is very useful, but I had already done that
Hey guys, I've had my S2 for about a month and decided to root it using Chain fire's post. I have the Telstra firmware(just incase), stock kernel and CF-root kernel, after rooting I flashed the stock kernel to remove the warning triangle, I still had root access and then tried using CWM zImage via the app... my phone rebooted into recovery mode but says:
-- copying media files...
Successfully copied meida files
# MANUAL MODE #
-- Updating application..
successfull...--Applying Multi-CSC...
Installing " "
Can't access to '/system/csc/TEL/sytem/
Successfully applied multi-CSC
then finally the normal(not clockworkmod from root) android recover options appear.
Does anyone know of a different root to CF-Root where I can use a stock kernel that doesn't hijack the recovery options?.

Recovery is part of the kernel, so all kernels will overwrite the recovery when you flash them.
Follow the guide in the cf-root thread to the letter to get CWM and remove the yellow triangle, or buy a USB jig and use it to reset counter and remove the yellow triangle.
I did exactly as the guide says, recovery now only works if I don't use a stock kernel.
I went into download mode, opened odin making sure repartition isn't checked, loaded CF-root-KF4.tar, got root access, the phone rebooted i made sure it was rooted and checked out CWM recovery then went into download mode again and flashed the stock kernel from Intratech's Telstra Carrier branded firmwares Thread and root was fine so I checked CWM recovery and it was gone, I then extracted zImage from the CFroot I flashed and placed on the phone /sdcard I ran CWManager clciked flash kernel>Zimage and it rebooted into the normal recovery mode with CSC crap there still.
How is there not a root program that doesn't modify (doesn't change features) recovery mode? I'd like to update by KIES in future and need to keep the stock kernel I believe.
Other root methods are posted on XDA .

You *need* a custom kernel in order to have CWM recovery on the SGS2, if you just want root, you can flash a root kernel, then flash your stock kernel.
You will LOSE CWM but KEEP root.
Also CF-root is a stock kernel, just with a modified initramfs (added root and CWM recovery)
I think JJ was referring to searching the forum and you will find the other methods..... So not useless unless you need spoon feeding

When I said Useless I mean not being helpful, and it wasn't I've checked the forums which I thought I read superoneclick doesn't work on retail phones.
and on the and then there was root I saw the guide has been super-ceded by CF-root, most guides on youtube are CF-root I'll have to just look around more.
@Veyka is the superoneclick root working? and what's the alternative you suggest?.
My phone has been rooted for a while now. I've tried various custom roms.
I recently did a format and installed Villainrom 2.0. When i try to use root apps such as mobileOdin or battery calbiration, it says the phone is not rooted.
When i go to superuser and try to update my SU binary it says the installed version is LEGACY.
when i try to update it, it gives me an error saying failed to find currently installed su binary. Update cannot continue.
Any help would be appreciated.
I'm trying to flash ICS using mobile odin (because odin doesn't detect my phone). But obviously need root access. Which i'm quite sure i have because my CWM is working fine.
Root it again save all the messing about .
Root + CWM .

Reflash Kernel first.
If also doesn't work, reflash rom or directly new rom ;-)
CHEERS ;-)

Does it have to be Odin that's used to root and install cwm....
Feel stupid now.
Thanks for the advice guys.
Turns out i just had to download the latest SU binary.
I already rooted the phone using CF ROOT. running stock 4.1.2
Can I use ROM MANAGER to flash CWM recovery ?

there are many guides for rooting and installing CWM, but I'd like to know if I can use ROM MANAGER to flash CWM on a rooted S3 ?

AFAIK, ROM Manager is not fully compatible with CF-ROOT/JB (don't remember which, just that it was incompatible with one of those two). Better flash through ODIN.

Try this instead TWRP market download link in first post
Does the same job, download the app from the market and install then install the recovery script from the menu button
Just to clarify, I can install TWRP as suggested above after the phone was rooted via CF ROOT ?
No need to also unlock the boot loader ?
the bootloader is not locked
