I started with a rooted S4 SGH-I337 running 4.3. Was eating batteries with AT&T's OTA push failing every day so I decided to flash a new 4.2.2 ROM using "For MK2 Base Users (never took NB1 OTA)" instructions Here. After the reboot, the "Samsung Custom" splash stayed on for an hour until I rebooted manually. Now it remains stuck in the splash screen unless I boot into download mode.
I've tried flashing a new ROM and partition using these instructions and (I337MK2_Full_Odin_Tar.tar.md5) / (SGS-I337_16GB.pit) but have not seen any difference. Here is where I'm sitting now.
Kies doesn't see the phone at all.

I've spent days reading threads and haven't found anything that seems helpful at this point. Does anyone have any helpful suggestions or links to a thread that may help?
