Just want to share..yesterday i tick repartition while flashing xxkg1, and i used the .pit file as well.. but, apparently my old data still available in the internal storage, e.g files that i pushed in, and even in CWM there are still my old backup files.. so, by repartioning, i think it will not clean up the storage. but there is possibility of data loss if only the data located at the new partition area.
