Root Samsung Galaxy S2 GT-i9100
I am completely new at this and wanted to find out how exactly to root a Samsung Galaxy s2. I have read around forums and one says one thing and the other says something help. Can you help me. Can you root it through the stock kernel or do you need another one and how do you get it with no yellow triangle (without a USB Jig). Then how exactly do you put a rom on and super user. Also how do you remove root and the rom if you want to go back to stock. Thank you any help appreciated.
