I'm not sure you needed to do that being that it's based on cyanogenmod. On the first page of the rom there's a troubleshooting guide that may help. I just looked at it and there's help specifically for your situation that I'm sure will help so try reading that first. I wasn't running cm before I flashed it. I was using sky ics and was having a bunch of fc's so I actually returned to my stock rom, but sky ics was nice when not fc'ing so I don't want to take anything away from that seanz. It just was not running smoothly for me. This rom is really smooth, and I haven't had any problems at all. So basically, my method was probably not ideal for most people(going back to stock). If you can get back to your current rom try checking out the instructions for install from that perspective (not wiping data/fac reset) and just installing the zip. Breeze through the pages, as there's only about 30 so it's not like there's thousands of posts yet.
