I did something wrong. I installed init.d then copied 77tweaks and renice into the init.d file. I rebooted it once and it went fine. Then after i replaced the build.prop file with the down loaded one I restarted it and it went into boot loop. At least I guess that's what it is when it turns the Samsung screen off and on and won't go past it. I re-odin'd Tweaked plus cwm and fixed it.
Did you reset the permissions after you replaced the build prop...also just for future reference if you download the build prop from tweaktools before you do anything then all you have to do is flash it from the tweaktools folder on your sd card if something goes wrong
