Does this have the same problem as flashing a root kernel, where there are problems mounting secure storage after?

This works perfectly (if you actually READ the title and instructions)!

Thanks mate. :)

This worked fine but I have a couple of questions..

When I "flash" it from stock recovery, it's volatile, reboot and it's gone. Is that expected?

Also, it doesn't grant root adb, is that also part of the deal?

Finally, what on earth did I press to get a counter in the bottom corner, it counted to about 8k before I got bored of waiting and pulled the battery.

Anyway,

For the sceptics, it does work if you use it properly, does what it's supposed to.

Don't forget, rooting this way won't give you remount capabilities by "adb remount", because kernel is still secured.

If I want to try this to get as stock as possible and have my SD issues fixed, I'll just need to flash the ICS bootloader from KPH and the stock KPH kernel, correct?

Are these components around that somebody could point me to, please?

Does the CWM recovery disappear on reboot?

Still the same issue.
SU permissions are fine but busybox is not working...
Try using luckypatcher and you'll see.
Root is there but it is not complete. Some functionality is lost.
Still... appquarantine does work, droidwall also so not all is lost.
Anyway, great work and elegant solution to keep the yellow triangle away.

If I'm already rooted with CF-Root and I want to use this to fix the SD problem, can I just flash the stock kernel and then use these files to keep root and busybox and CWM recovery?

Thanks!!!
You sir are great, it is working as it should now.
One Little, Tiny problem, every time I reboot to recovery I get stock recovery and not the CWM installed through your patch, HOW COME??

Is there anyway to get to that CWM recovery or does it reset on each boot??

The recovery IS NOT persistent.

So you'll either have to flash a new kernel/recovery via ODIN (PC) or Mobile ODIN.

    Simple way to root and unroot stock kernel without flashing insecure kernel.
    Don't worry about custom counter and yellow triangle, with this method they never appear, because we only rooting, it's a rooting script not a custom kernel.
    This rooting script included Busybox installer.

    Why do I get no answers to my questions?

    Are there so evident? Are they answered yet?

    There are bad questions?

    I just want to learn what the software does!!

    :(:(:(

    Yes they are evident and answered many times (in other threads, and on interwebs). Questions asked are NEVER bad, just that the place you are asking is not appropriate for those questions.

    Let me try this (but promise that you will do the research on your own now, and also in future, before you tweak your device):

    As far as file 1 is concerned: You really need to read across the internet. Just Search "What is Clockworkmod recovery" and you will get your answer. Basically it is a custom console to recover the OS. The basic job is to install OS updates, and delete user data if required. CWM gives you more options than the standard recovery on any device.

    SU (superuser app) controls the superuser access to applications. Once this is installed you can control which apps get access (It will ask you for permission).

    Busybox is a collection of utilities from Linux. These are utilities that are not available on android by default. If you have worked on linux you will have separate executables for each of these utilities, busybox combines them in one.

    So effectively they do modify stuff on your phone. Although, in my experience, nothing that will damage your device. These have been written by true masters and used by millions.

    Regarding question 2:
    Read the post 1, and with the answers already provided to your questions above you will be able to figure out if this will work with your device. It has worked with ICS on my device.
    If you are not comfortable with/do not know about tweaking/rooting your device, please avoid making changes until you learn more.
    I understand your hesitation, I spent a month reading hundreds of posts here before I rooted my device.

    Hit thanks on Rachmat's OP (and this post if you like :D ) if this helped you. :)

    Super Method for Rooting SGS2

    I Fully Appreciate your work​
    ,:)

    Superb Way to Root without Triangle!

    Thanks you very much!;)

    ---------- Post added at 10:39 PM ---------- Previous post was at 10:25 PM ----------

    Im abit confused here... How can I flash those ZIPS if I have no recovery?

    My SGS2 is BRAND NEW. I want to root it but I cant find a unsecure kernel that matches my current one (XWKI8)

    Also, if I do flash the unsecure one, how the hell do I get the original one back (as Im unable to back up because im not root...)

    HELP please...

    First of All, you should update your stock rom to LPQ (4.0.3) ICS version, then

    download all zips from following:

    http://download.clockworkmod.com/recoveries/recovery-clockwork-4.0.1.5-galaxys2.zip

    https://dl.dropbox.com/u/34053267/SU-Busybox-Installer.zip

    http://dl.dropbox.com/u/34053267/SU-Installer-signed.zip

    After downloading, you should copy these files in to your Phone Both Memories (SD CARD & Internal Storage)

    Turn off your phone
    and follow Rachmat3 steps
    1. Go to recovery.
    (Vol-UP + Home + Power> release power button after Samsung logo appear)

    2. Choose apply update from external storage.

    3. Choose recovery-clockwork-4.0.1.5-galaxys2.zip and wait until CWM recovery appear.

    4. Choose install zip from sdcard.

    5. Choose and Install SU-Busybox-Installer.zip

    6. Choose and Install SU-Installer-signed.zip

    7. Reboot System.

    You are done and now your device is Rooted!

    Hope you understand!
