Hi, i was new to Android platform. I was following this thread to root my galaxy s2. [GUIDE] And then there was ROOT ! - xda-developers However there is a step i can't get it right. Under "Long guide (for beginners)", the guide told me to start Odin, but i do not know how to start the Odin. The screen seem to hang whenever i pressed volume up to enter to the odin starting screen. I appreciate your help. Thank you..
