Need some advice bro. I pulled the firmware from xda ( i think u the one who put up the link to multiupload).
I used Kies to update my firmware, then using the file from multiupload, I extract the zImage and made into a .tar. I flash with the previous rooted kernel...ok... have yellow triange... but when i flash again with the kernel built from extracted zImage, Odin just sit there for some time and not responding, its checking file and nothing happen. So I yank out the cable and after that I get a logo with a phone and pc and says not connecting..... use USB jig also dont go away...

So i put back your multiupload file, and then pit files and I flash again even though got that logo above, success, it come back alive...

Not sure if extract zImage and making a .tar archive from it is right way to do this. I inspect previous stock kernel, its just a rebuild from zImage extract from the K1 firmware. What possibly u think I miss out?

Waa pun pening lo... maybe something fundamental I miss...sorry I am very noob to Android, just 3 weeks.
Anyway here is the kernel file i made...donno if its of use for inspection ..

Any advice is highly appreciated. If its you the same person in xda too, salute.

KJ2 firmware is better than KI1 or not?

KJ2 is better for me... and if u wanna root KJ2 u need to use MyGKernel from xda since its the only kernel known to work successfully in rooting ur phone and confirm working wifi but there is another working insecure kernel for DZKHI1 that can be use also... but u wont get to get rid off the yellow triangle in boot since KJ2 still dont have stock kernel to flash with...
but ask ur self do u really need to root ur phone rite now what apps do u really need to use if not just use stock rom for now and wait for a little while until someone make us our own custom rom ... 

thx..i'll change tu KJ2 now and i'm stick to the stock rom..

that is a wise choice as bro @waveweaver said "Better do your own customize using launcher and theme app from market." there are still lot of stuff to do even with out rooting like games are all HD so play with them...

for those sucessfully root their i9100g with firmware DZKI1...
and if u wan to upgrade to the latest DZKJ2 version with root...
u can use full firmware DZKJ2 and then use MyGKernal to root it...
after that ur phone is now DZKJ2 with root...
btw there's a yellow triangle when u start up...but no prob at all

how to usb jig?

If your phone have old bootloader then just chuck in the usb jig and your phone will go into auto download mode and the yellow triangle will disappear like magic ~LOL~
