Right out of tge gate, there is no stock 4.4.2 for this device. Not official anyway. 4.1.2 is official OS.
Status 7 means your recovery needs updating.
CWM does work and the newest CWM touch is just dandy.
I would try going all the way back. You need to be totally clean.
Go to Kies and go with emergency firmware recovery.
Get back to stock and see what is working.
Clean clean clean, the best way for anyone to help you. You would be at the best starting point.
Maybe do a little reading as many of your issues have been documented and solved. None of them are major.
Start from scratch and folks can get you running again.
