Actually it is a epic touch issue and cwm issue. I earlier just glanced through the thread because a friend told me about it. But after going back, It was really more to do with flashing a ics Rom and then flashing a backup of gingerbread. The partitions were different as to what was stored on them. Causing the issue. I was told this was only an issue when using cwm version 9.

Just Flash It !!!
