With odin, I think I have succeeded on upgrading to 2.3.3 gingerbread from rooted 2.2.1. But my problem is rooting 2.3.3 again as I saved all the TI backups on SD card. I tried Odin to root the phone with zimage-root and zimage. It seemed successful without any error message. But problem is I cannot see TI app in my apps or home screen. What is going on? Does this mean rooting failed? But wireless tether seemed to be working fine with SU.
