For everyone that is having problems with FOTA over a rooted 307 (update starts and terminates a few seconds in with RedBend error 318).
I went around this by:
Flash ONLY system from the 307 FTF (http://forum.xda-developers.com/showthread.php?t=2325990&highlight=ftf)
Root again
Reinstall SuperSU
Set SuperSU system app
Run FOTA
This has the advantage that you do not loose all apps/settings.
