Bricked SPH-L720 after modem firmware upgrade attempt. Help!

Phone: SPH-L720
Baseband: L720VPUAMDL
OS: PAC-ROM 5.1.1

Attempted to update the modem from MDL to OK3 with only the modem.bin and NON-HLOS.bin file via Odin 3.10.7. The upgrade failed. Now the phone fails to boot and displays the message "Firmware upgrade encountered an issue. Please select recovery mode in Kies and try again". ODin was run "as administrator" and I have swapped cables and USB ports. The phone will go into download mode and display the follow screen:

PRODUCT NAME: SPH-L720
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: Custom
KNOX KEARNEL LOCK: 0xfffffffC
KNOX WARRANTY VOID: 0xFFFFFFFC
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE: enabled

I attempted to reload the factory image L720vpumdl and it failed with a missing PIT partition error. see below.

I attempted again with the same image and added a L72016GB pit file.

With PIt file added:
<OSM> Enter CS for MD5..
<OSM> Binary Check MD5.. Do not unplug the cable..

<ID:0/003> DO NOT TURN OFF TARGET!!
<ID:0/003> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
<ID:0/003> Removed!!

If anyone has any suggestion or a known solution I would apreciate it. I do have access to another SPH-L720 but it baseband is on NAE.

Thanks
