[Odin-EC05] Froyo EC05 Prerooted/CWM v2.5.1.0 RFS (Odexed) - Android Forums You have to register on the site to be able to use it. This will get you from EB13 to EC05 with root. I did it and it worked. It seems people that rooted and went with EXT4, are having some issues. I had only rooted, but kept everything stock, so if you are in that situation, this should work for you. Thank the person who posted it if you like.
