sorry got a noob question! beside check the battery method to confirm is i9100g! Is there still got other way to check?

the g version better izzit? how come the price lower 1?

still no custom firmware?

Thank you I9100G and IntraTech. Am a "G" owner. Share same feeling with ZenkiMon, that we're cheated by Samsung Malaysia. Anyway, I managed to root the 9100G but before downloading/installing apps, I find the camera unstable. Now I cannot use the camera...giving "Camera Failed".
Any ideas, please. Have flashed and reflashed 6 times already. Sometines the camera works initially but after a few minutes, it fails even without installing any apps..    

Congratz for those who have succesfull in rooting their phone. If you have Superuser app and CWM then its good. Otherwise download that two apps. Use CWM to make full backup of you rom. Incase shit happen, you can flash back your original rom using CWM. No need to use Odin anymore as flashing using Odin increase your binary counter.
Next download Titanium Backup from market. Use it to backup all you apps. Again if shit happen and you have to do hard/factory reset, you'll going to lose all your apps. Just download Titanium Backup again and then use it to restore back all your missing apps. Easy huhh.. :-P
The G version still dont have custom rom at the.moment but it doesn't stop you from customized your phone. You can't unleash you phone full potential yet as you're using stock rom but you still can customized it to suit your personality.
Download launcher from market. There are a few good free launcher such as LauncherPro, ADW Launcher, Go Launcher EX and even ICS Launcher. Use the one that you like most. Then start customized it by downloading Theme. There are dozen of Theme that you can use together with your Launcher. After that download Icon Pack so you can change and make your icons more beautiful. There are also Fonts Pack where you can add more fonts style in your phone. Try mix and match all of this. You'll learn new things on how to customized and beautify your own phone. There are tons of thing that you can do and learn. Before i stop the ceramah, download Android Assistant app to monitor your battery condition and also to monitor any roque apps that may drain your battery. Another good app is BetterBatteryStats app. You can download this paid app from market or download the apk from xda-forum. Use this good app to monitor if your phone got any wakelocks. Meaning monitor apps that keep running even when your screen is off. Try to minimize or eliminate this wakelocks as it keep your phone from deep sleep thus draining your battery. Ok guys and gals.,
Happy Exploring :-)

bro waveweaver.. can u explain step by step how to root by using ur method.like use superuser and cwm like u said.explain step by step and software download link like bro I9100G did.pls bro.. thanks

Good Morning to all....and speaking about SGS 9100G,I found out that when you go to contact,both sim and phone are displayed!This does not happen in SGS 9100(as I happened to also owned one now....having both phones!).SGS2 9100 just display phone contact,I just have no idea how to see the sim contact(wether to know the amount of sim contact,let alone to update...!).So in this aspect SGS2 9100G is better.

so, how do i install cwm for Ki1 firmware? as i see it, we will use the stock kernel. anyway, i also tried the insecure kernel from xda for i9100G KI1, but still no cwm in it.

This is the first time I'm writing a tutorial, so please bear with me a little, key? I've had some requests and decided just to write up a simple tutorial. Although I must stress out that flashing your phone might void warranty, and I'm NOT in anyway an expert and I can't guarantee you everything will work out. I'm NOT going to take any responsibility if you permanently bricked your phone. Although my experience says, it is very hard to really brick a Galaxy SII.

PLEASE SHARE YOUR RESULTS/PROBLEMS/SUCCESSES/FAILURES

What you'll need;

1. A Galaxy SII I9100G phone. The G is required!. Check behind your battery
2. USB cable suitable for the phone
3. Samsung driver or KIES installed. But please close KIES before proceeding Go Google if you don't have one
4. DZKI1 original full firmware: http://www.multiupload.com/6L8BALT56F
5. DZKI1 original kernel image: http://www.multiupload.com/AS18CIXQNX
6. ZCKH4 rooted  kernel image: http://forum.xda-developers.com/showpost.p...52&postcount=22
7. I9100G PIT file: http://forum.lowyat.net/index.php?act=Atta...post&id=2465180

The idea;

Update your phone to the latest DZKI1 firmware, then flash a rooted ZCKH4 to get the Superuser application. (ZCKH4 is compatible with I9100Gs, although, your wifi will not work). Update the superuser application, and flash back the original DZKI1 to fix your wifi.

The Steps

Preparation
Firstly, extract everything into its own folder. Switch off the phone and take out SIM and SD card. To enter download mode, hold down Volume Down button + OK button(home) simultaneously and THEN press the Power Button. Once you see the warning logo, IMMEDIATELY release all buttons and push ONLY the Volume UP button. You'll see "ODIN MODE" and the android logo. Plug in the phone to your pc and let the new driver installation finish. WARNING, please DO NOT continue if you are having problem with the driver installation.

Updating Your Firmware
Please follow the instruction exactly, otherwise, you'll probably get into complicated problems.  Get to the Odin folder and run the application. Click PIT button and browse for the "omap4_all_20110627_emmc.pit" file. Click the PDA button and include the DZKI1 original full firmware. It's filename should be .tar. Click "Start" and wait until its done. The phone will restart and you'll have a new firmware. If you stucked on the galaxy logo (NOT THE YELLOW TRIANGLE case), please google for "Galaxy s2 clear cache". If everything went smoothly, you'll be up and away setting up the google account information.

Flash The Rooted Kernel
Please follow the above instruction again, substituting the DZKI1 original full firmware with ZCKH4 rooted  kernel image. Once your phone booted up, you'll be able to find the Superuser Icon;



That's mean your phone has successfully been rooted! Yay!

But, still not done yet, because your custom kernel is causing your wifi to malfunction and the yellow triangle to appear. We'll address that by reflashing the DZKI1 original kernel image

Flash The Original Kernel Image
Just follow the "Updating Your Firmware" substituting the DZKI1 original full firmware with DZKI1 original kernel image

You'r done! Now you have a rooted phone meanwhile maintaining original firmware. YAY!!!
