Hello and welcome to Android Forums lardos
Normally I quote a new poster's problem but as you have given such a concise and lengthy description, which does help, I won't bother.
In a nutshell, it would appear that you have become, "Flash Happy", in an effort to sort out your problems... which they have not.
Assuming that you are still rooted, try flashing the PhilZ.tar in recovery via Odin as per #1.1
of the PhilZ CWM Recovery - Dummies Guide
and see if that helps.
IMHO the time has come to bite the bullet, and do a Factory Reset and flash a stock Samsung firmware using Odin before going on to root
and recovery and custom ROMs.
Just a thought... you haven't, during all your flashes, changed your .PIT file by any chance have you?
