Glad I could help happy you got it working properly

What baseband are you on... I want to downgrade but if odin fails usually you get the upgrade failure connect to kies message on bootup. I solved that with flashing the of2 tar kernel. I thought about flashing this but i believe it's unsafe for of2. Any little flashing error this phone gets a bootup problem or bootloop. If you're willing to odin things try this...... It's my next attempt to obtain root.... http://forum.xda-developers.com/show....php?t=2785363
