Can you explain step by step and what should I download if possible ?
It goes without saying but I'll say it anyway...I'm not responsible if you mess up your device...Also, I'm not sure it will work for your Korean device.
This assumes that you have an external SD Card - I've included several extra steps for safety and to MAKE SURE that you do NOT erase your SD card accidentally - You would not be the 1st person to do that...If you do not have an external SD card, ignore these instructions:
Step 1: Download any GB kernel - here's one that I know works for USA device: http://forum.xda-developers.com/show....php?t=2318550
Step 2: Download any GB Rom - here's one that I know works for USA device: http://forum.xda-developers.com/show....php?t=2123715
Step 3: put both files on your external SD card
Step 4: Using TWRP, install the GB kernel
Step 5: Power off your device
Step 6: Physically remove your external SD card
Step 7: Boot into CWM recovery by pressing and holding both the volume up and power buttons until the Samsung logo appears
Step 8: Wipe data, cache, Dalvik (in advanced), & format system (in mounts & storage)
Step 9: power off the device
Step 10: physically re-insert your external SD card
Step 11: Boot into CWM recovery by pressing and holding both the volume up and power buttons until the Samsung logo appears
Step 12: install the GB Rom
Step 13: reboot
