I just tried to root my phone using a method that I found on Youtube using Root S2 and Odin. Basically it effed up my phone. I can't connect to the net, make calls, have no service, and there's a plane icon that is constantly next to my battery icon. I tried to use Root S2 while it was connected to my computer after using Odin but it kept telling me my phone needed to be connected by USB which it was. I have no idea what to do but my Kernel on my phone has the following letters: XWKDD and XWKDD_insecure.tar is the kernel I used and loaded up. Can someone please tell me how to restore my phone back to how it originally was and explain to me what I can do to root it properly. I'd really appreciate it!
