Hi guys, I just got a used S2 G version. Thinking of rooting. I've already updated to the latest ICS through Kies. So I am now gonna follow Advanced Method 2. So it's as simple as that right?

Reason I am thinking of rooting is coz my GPS is not locking. So might rooting help?

How do I un-root if I needed to, for warranty claims

CWM is not kernel FYI..

it's a modded recovery mode.

CWM is not rooted as well. both are separated. some CWM comes along with root or vice versa..

u can flash a custom ROM without root at all, u just need a recovery mode. although most custom ROM requires root or comes with root.

basically there are three different things here.

ROOT, RECOVERY, ROM

KERNEL is different.

even thou i see u r good at flashing, but it doesn't seem that u understand the difference. Hope this clears your confusion.

hi all,

No prob bro. glad that problem is solved.

ok now. if you wanna upgrade to ICS, just download the ICS firmware ive posted above and flash the stock firmware using ODIN.

once that is done, in order to get rooted :

Method 1:

Advantages: Easy to do, permanent ClockworkMod recovery achieved.
Disadvantages: Increases flash counter. (No yellow triangle though.)

Prerequisites: Codeworkx's LP7 or ICS Kernel: http://forum.xda-developers.com/show....php?t=1631934
root.zip here: http://www.mediafire.com/?w3zzodjc1b8kqdhStep 1: Download Codeworkx's LP7/ICS kernel and flash it using Odin.
Step 2: Put root.zip on either the internal or external SD card.
Step 3: Boot into ClockworkMod recovery by pressing Home Button + Volume Up key + Power key while your phone is turned off.
Step 4: Select install zip from sdcard.
Step 5: Select choose zip from sdcard/internal sdcard, depending on where you put root.zip.
Step 6: Flash root.zip and reboot.

Congratulations, you should now have root access.

Method 2:

Advantages: No flash counter increase or yellow triangle.
Disadvantages: Temporary ClockworkMod Recovery. You must have an External SD Card!

Prerequisites: The CWM.zip and root.zip from this file: http://www.mediafire.com/?yh2ii6mbozz9243Step 1: Put the CWM.zip onto your EXTERNAL SD Card and root.zip on external OR internal SD.
Step 2: Get into the stock recovery mode by pressing Home Button + Volume Up key + Power key while your phone is turned off.
Step 3: From there, select apply update from external storage, and select the CWM.zip.
Step 4: You should now be taken to CWM Touch Recovery, where you should select install zip from sdcard.
Step 5: Select choose zip from sdcard/internal sdcard, depending on where you put root.zip. (Your internal and external sdcard might have their locations switched with the other, so double-check!)
Step 6: Flash root.zip and reboot.

Congratulations, you should now have root access without binary increase or a yellow triangle.
ADVANCED Method 2:

Advantages: No flash counter increase or yellow triangle. Permanent ClockworkMod Recovery.
Disadvantages: More difficult than the other methods, but this will give you the best result once achieved.

Prerequisites: Properly executed all steps from Method 2 and obtained root.
Codeworkx's LP7 or ICS Kernel: http://forum.xda-developers.com/show....php?t=1631934

Step 1: Download and install ktool from Google play.
Step 2: Extract the contents of Codeworkx's LP7 or ICS kernel.
Step 3: Find the file "zimage" and copy it onto your phone's storage.
Step 4: Use ktool to flash the "zimage" file. Reboot.

Congratulations, you now have achieved root with permanent ClockworkMod Recovery AND no flash counter increase.

good luck bro

actually i dont understand your issue. ClockWorkMod kernel is required in order to be rooted. only then you can flash CM9. without a rooted kernel you cnat flash cm9

The phone doesn't contains cwm so there is no way I can access recovery. The owner fail root his phone thus stuck at this stage

1 . CWM is not a kernel, it's just a recovery mode.

2. codeworkx mentioned don't flash this on CM9, bcz CM9 is running a different kernel and will not work with this. U need to flash this BEFORE flashing CM9, so that CM9 will overwrite the existing kernels.

3.Fundamentals of flashing a new ROM requires ONLY CWM. Root or no root doesn't matter, cz the ROM itself will be pre-rooted if it requires root for it's custom apps. Kernels also separate one. Custom ROMs can work with stock kernels, unless they require special tweaking, then they will include their own kernels within the ROM .zip file.
u r confused with the kernels and recovery, that's y u can't really understand his situation.

Yeah! Bro wira_lover here helped me a lot in flashing my phone to ICS. Thanks to his guide,flashed my phone to ICS and got it rooted too! Thanks bro!   

yes!! I rooted my phone! using method 2 from here! http://forum.xda-developers.com/showthread.php?t=1679778

got superuser app means root already right?

okay. I read a few threads about the Q&A on rooting. But what exactly is ClockworkMod Recovery?

Does flashing our radio modem have any effect on the cellular reception?

im still on Stock, 4.0.3... dint do any mod on the device so far.

Ohh, then i think i will try out the divine ROM that you suggested... means after root, need to flash a ROM into the device ? and where can i find the divine rom tutorial ?

Bro, i decide to use this method, issit okay for a newbie like me ? i need to complete method 2 1st then only can proceed to below ADVANCED method ? :

-----------------------------------------
ADVANCED Method 2:

Guys,how do I set my phone internet browser to always display in landscape? Back on GB,there was an option in the settings that made it possible. But now on ICS,there's no such option. Im using stock ROM and browser,fyi. Thanks! Also,i disabled auto orientation because i don't need it.
