To completely remove every trace you'll also have to reset the custom binary counter. You need special hardware for that though: http://xdaforums.com/showthread.php?t=1068522

True that. Nevertheless (if I understand things correctly), these steps should remove every other trace other than the custom binary counter:

1: Remove superuser and busybox (adb or manually):
adb shell
su
rm -r /system/app/Superuser.apk
rm -r /system/xbin/busybox
rm -r /system/bin/su

* Flash stock ROM and kernel through Odin. Boot up.

* Settings->Privacy->Factory data reset. Reboot.

Please correct me if I'm wrong :)

hmm.... now we have CWM also for SGS2, where r those Custom ROM cookers ? who kept complaining about lack of CWM for SGS2 ???

here u go devs, now can we expect some extra tweaks & modifications to so called custom ROMs ??? because so far, there r hardly any customisations done for the available Custom ROMs... not being so circastic here, just pointing out the fact... pls dont feel loffended devs...

we all love ur work & we will..... but keep up ur good work.... hoping for thee better modifications & tweaks for this bad boy thats all.... keep it up... expecting more & more custom ROMs with nice optimizations....

So... It is out for less than 18 hours, and you are already complaining? You have ROMs available already. I worked round the issues related to lack of CWM by writing an app to install tweaks to your custom ROM...

Then you go "where are the custom ROMs". If that's not rude, I don't know what is. They are already here- see the dev forum. But remember some of us have "real jobs" too... XDA isn't my job, and I've got other things to do as well...

you would also need to delete every link pointing to the busybox binary with a command like "find /system -lname *busybox" (untested)
flashing a stock rom should overwrite the system partition so I guess it's not needed anyway.

Sorry about a very nooby question... After using CF-root how do we remove all and every trace of custom kernel for warranty purpose..

Will flashing an official Samsung ROM do the trick?

Thanks in advance..

Once again sorry if this has been covered already.

Flash a non-custom rom. See intra tech thread.
I say this because I am presuming if you are asking for reversible process you still have the basics like odin, and functioning usb, power keys and the like.

I just noticed, after flashing the ke7 kernel, I can't access the system wiles with adb anymore.

then I type "adb remount" it gives me this error message:
"remount failed: Operation not permitted"

is there a way to mount the /system and /data folder with RW rights within ADB?

A properly rooted ROM does not allow that indeed...

You need to do this through the shell:

adb shell
su
mount -o rw,remount /system

This is why I stopped responding to PMs from this member. I found him quite demanding, it was always "HELP MEEEEE BUDDY! Help me now!!" kind of thing. This dude needs to chill out a bit, learn to be patient.

Hmmm... flashed KE7 version with ODIN. Success. Rebooted with yellow !. (I had come from stock KE7 kernel on VR1.1)

Kernel under "about" shows as standard KE7 details and I can't see CWM under Applications.

Where did I go wrong?

EDIT: CWM Manager shows up in my app listing for Launcher7. So when you mean it is under "Applications", I assume you mean the app drawer? I went looking in Settings - Applications!

It does root but you also get a very useful custom recovery called clockworkmod.
From CWM recovery you can flash roms and kernels directly from the phone, make full systema backups and other nice things :)
See the OP.

    This rooted kernel is for the "rooting beginners" and those who want to keep as close to stock as possible. CF-Root takes the kernel from an original Samsung firmware, and just adds root, busybox, and ClockWorkMod (CWM4/5) recovery

    THIS IS NOT A ROM - it is only a modified kernel. You need to have the relevant firmware already on your device. You do NOT need to wipe anything for this patch. You DO need to read the instructions. PLEASE READ THIS ENTIRE POST!

    Donate
    There have now been nearly 8.000.000 downloads of CF-Root for various devices (see for example Galaxy S1, Galaxy Tab 7", and Galaxy S2), and many more if you include ROMs, kernels, etc that use it. Don't be a leech, buy me a beer (and use the "Thanks" button!). Imagine if every CF-Root user had donated me $1... :)

    Yellow triangle and flash counter
    On Ice Cream Sandwich builds (only), get rid of the yellow triangle and flash counter after flashing using my Triangle Away app!

    Features
    - The kernel is fully stock and taken from the original firmware, with just the following added:
    - Root
    - Busybox v1.16.2androidminimal (from CWM)
    - Integrated CWM 4.0.0.2

    CF-Root v4.1 and older
    - Superuser 2.3.6.1
    - "Secure" mode

    CF-Root v4.2 and newer
    - Superuser 3.0
    - "Insecure" mode

    CF-Root v5.0 and newer
    - "Insecure" mode

    - Integrated CWM v5
    - CWM Manager v3

    CF-Root v5.4 and newer
    - SuperSU (replaces Superuser)
    - "Fake-secure" (ro.secure=1, but ADB is patched to run as ro.secure=0)
    - Fixed ICS SD card issue

    CF-Root v5.5 and newer
    - CWM updated to v5.5

    Instructions - ODIN (short)
    - Flash CF-Root-xxx-vX.X.tar (from the attached zip) as PDA in ODIN, without repartition. Done.

    Instructions - ODIN (long)
    - Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
    - Unzip the attached CF-Root-xxx-vX.X.zip
    - (USB) Disconnect your phone from your computer
    - Start ODIN
    - Click the PDA button, and select CF-Root-xxx-vX.X.tar
    - Put your phone in download mode
    - (USB) Connect the phone to your computer
    - Make sure repartition is NOT checked
    - Click the START button
    - Wait for the phone to reboot
    - Done (if it took you more than 30 seconds, you need practise!)

    Instructions - If you already have CF-Root
    - Copy the zip file to your SD card
    - Stop sharing SD card with computer over USB, unplug the cable, etc
    - Applications -> CWM -> Flash kernel. Select the ZIP file on your SD card.
    - Done

    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.

    ClockworkMod
    CF-Root includes a custom version of CWM4. I always make custom versions, as the originals often do not take some Samsung specific things into account.

    CF-Root/CWM4 is NOT compatible with ROM Manager! Manage/perform your backup/restores from CWM directly or using the CWM Manager application included with CF-Root

    - Booting into recovery will immediately give you CWM. The standard recovery will only be started if a Samsung package is detected.
    - ADB is functional in recovery, however it may take up to a minute for it to start up after booting into recovery.
    - When connected to ADB in recovery, you need to use "rootsh" command to get root, instead of "su". This will not prompt you, it will just give you root. Obviously the "rootsh" command does not work when booted normally.

    NOTICE: On CF-Root before 4.0, the kernel was not backed up or restored, on 4.0 it is. This can also cause issues restoring pre-4.0 nandroid backups. In that case, use "advanced restore" inside CWM4 and restore a backup's portions one by one.

    CWM Manager
    Because of incompatibility with ROM Manager, I wrote and included "CWM Manager". This is a new app (as of March 30, 2011). You can find it under Applications -> CWM. It is much faster to use than manually booting into CWM and selecting these options.

    Features:
    - Boot to CWM
    - Backup firmware
    - Restore backups (CF-Root v5.0: including partition selection)
    - Delete backups
    - Install APKs
    - Flash CWM3/4/5 update.zip's
    - Flash kernels (zImage, zImage in TAR, zImage in ZIP, zImage in TAR in ZIP) - without changing warning triangle status or increasing flash counter
    --- without changing warning triangle status or increasing flash counter
    - CF-Root v5.0: Flash complete firmwares (seperate files as well as .tar and .tar.md5 archives, dump files in /sdcard/external_sd/firmware folder)
    --- without changing warning triangle status or increasing flash counter
    --- can pre-root new firmwares during flash

    Note: If you flash a different kernel, CWM Manager may remain installed. However, functions may not work, because they need kernel compatibility !

    Custom boot / init scripts
    CF-Root will execute the following scripts if present, in the order listed:

    - /system/etc/init.d/* (there can be many files here, no extensions! use #!)
    - /system/bin/customboot.sh (busybox sh)
    - /system/xbin/customboot.sh (busybox sh)
    - /data/local/customboot.sh (busybox sh)

    Please make sure you chown / chmod the scripts correctly so they can be executed. Pretty much root:root / 755.

    Custom boot animations and binaries
    CF-Root also supports custom boot animations:

    - /system/media/bootanimation.zip
    - /data/local/bootanimation.zip

    And custom boot binaries:

    - /data/local/bootanimation.bin

    Installing busybox over the included version
    It is possible to install a custom busybox over CF-Root v3.0 and newer. However, this is not without risk. CF-Root makes heavy use of scripting, and many CF-Root scripts rely on the internal busybox version. If you do install a seperate busybox version (always use "stericson" installer!), install it to /system/xbin. Installing it to /system/bin will mess things up for sure. Even if you do that part right, it may still break CF-Root, so make sure to make a backup before trying.

    How ?
    I wrote my own toolchain to ease patching of initramfs, and that is what all this is based on. Took me a few days to get it to this state. If this works right, however, next time it will probably take me a few hours tops :)

    Help! Which file do I use ?
    Listen closely, for I will say zis only once!

    Go to Settings -> About phone -> Kernel Version. Note the string present there:

    2.6.35.7-I9100XXKG1-CL349526

    What matters most (KG1) in this case, is in bold. Try to find the matching file under downloads:

    CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4.zip

    The XX and OXA identifiers are not that important. Usually a "KG1" kernel is a "KG1" kernel, and that is that. Sometimes (pretty rare) it happens there will be multiple different kernels with the same name in different firmwares, that are actually different. If this happens, they are usually only very minor changes and you should expect them to still be fully compatible. I include the "XX" and "OXA" identifiers so the very advanced users can deduce from which full firmware I have taken the kernel file.

    Don't worry too much, just find the matching download and use it. What if there is no matching download ? You can ask me to make one, but I can tell you right now, I very very rarely make CF-Root's for kernels on request, unless it is the very latest kernel that has been released by Samsung. In the latter case, be sure to let me know. If there's no match and I'm not making one, try finding the closest match. You should treat "KG1" as a number, but instead of 1-9, we have 1-9, A-Z (where A would be 10, and Z would be 35). "KG2" is really close to "KG1", "KF1" is not close to "KG1" at all. I hope that makes sense.

    These are general-purpose downloads. See the posts following this one for the kernels.

    Getting rid of that pesky warning triangle during boot, and upgrading your firmware

    Getting rid of that pesky warning triangle during boot

    On ICS, there is now a much easer way: Triangle Away

    It is definitely possible to remove that pesky warning triangle during boot when running a custom kernel, though you should be well aware that this method does NOT reset the custom kernel flash counter. The steps are not complicated, but they aren't easy either, so read well.

    (1) Make sure you have CF-Root flashed (see the first post). You must have the "CWM Manager" app available.

    (2) Make sure you have the same version of CF-Root extracted until you have the zImage file. (ZIP --> extract --> TAR --> extract --> zImage).

    (3) Push the zImage file to /sdcard . It must still be called zImage !

    (4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)

    (5) Reboot into download mode (adb reboot download, or boot the device with home and volume-down pressed)

    (6) Fire up ODIN, and flash the Samsung kernel

    (7) Boot the device with the stock kernel. CWM Manager will still be available.

    (8) Start CWM Manager, select Flash Kernel, and select the zImage from CF-Root you previously put on your SD-card. The kernel will flash and the device will reboot.

    (9) You will now notice you no longer have the warning triangle during boot, but you are actually running CF-Root with all it's goodies!

    (10) In the future, if you only use the Flash Kernel option inside CWM Manager instead of ODIN, the triangle will not return, neither will your flash counter increase. But keep in mind, that CWM Manager can only handle a direct "zImage" if you are NOT running a kernel with full busybox support (this is currently needed for flashing kernels out of .TAR and .ZIP files)

    CF-Root v5.0: Upgrading your firmware

    Important: This works ONLY on a CF-Root kernel !

    CWM Manager has the ability to flash firmware parts either from separate files (zImage, factoryfs.img, etc) or from .tar / .tar.md5 files that they usually come packaged in.

    - Download the firmware you want to flash
    - If you have a ZIP or RAR file, extract it until you have seperate files, or .tar / .tar.md5 files
    - Create a folder named 'firmware' on your external SD card
    - Copy the files you want to flash to this folder ( /sdcard/external_sd/firmware ). factoryfs ("system") is mandatory part at the moment.
    - TIP: If you are flashing a new firmware that already has a CF-Root kernel available, put it in the 'firmware' folder as well in zImage or .tar form (NOT .zip). Select it when asked which kernel to use, then use the "Flash normally" option later on.
    - Open the CWM Manager app
    - Select "Flash stock firmware"

    - At this point, CWM Manager will tell you about the firmware parts it has found, and which ones it will flash. It will also give you warnings about bootloaders and PIT files if those were found. If some firmware parts are present multiple times, it will ask you which file to use as source.

    - If what you are flashing includes both kernel and system parts, CWM Manager will warn you about this as you are about to lose root. It will provide you with three options:

    1: Keep CF-Root kernel
    Keeps the current CF-Root kernel, only flash the other parts. You will not lose root or CWM Recovery. You can flash a newer CF-Root kernel later (or maybe you have already done so), see 3.1 above.

    2: Pre-root system
    Flashes both kernel and system parts, but roots system during the flash. You will lose CWM Recovery, but you will keep root (if all goes well). The CWM Manager application will also remain, and allow you to flash the correct CF-Root kernel at a different time (if you have not done so before), see 3.1 above.

    3: Flash normally
    Doesn't do anything specific. If the kernel you are flashing is not a CF-Root (or similar) kernel, you will lose root, and CWM Recovery.

    - CWM Manager will reboot into CWM Recovery, and will flash the firmware, rebooting afterwards.

    The goods

    It is important you guys let me know of new stock kernels and ROMs, else no new CF-Root's will be made :)

    Note that I generally do not "back-port", in other words, I rarely make CF-Root's for old kernels/firmwares, and new features and fixes generally only appear for the very latest kernel/firmware.

    NOTE: Removed < 4.0 version of CF-Root
