I haven't had this issue before, which is odd, because I have been using the same rooting techniques/rom/cwm/phone for a while, and former tech support employee. I simply can not install any rom. After it installs, it reboots and either stays on the samsung screen or sits on the samsung screen for a while and then goes back to cwm. I have tried reformatting my sd card. I have successfully used odin back to 2.1, upgrade to 2.2, root using one click (I have never tried to root on 2.3). Then upgrade cwm to 18.104.22.168 and the problem starts all over again. Any ideas? Please and thank you.
