The only step I took was to reflash the DT recovery and it's working - thanks!This is normal, as Odin will reflash all system files including the recovery. (The storage should remain fine)
Yes, but you will probably have to create secondary FS partition again. Best restore one of your nandroid backups (CM10.2?) on the secondary FS partition and then flash devil2 kernel over both FSs.
