Right now I'm trying t oget my phone to boot w/o a sd card. It doesn't matter what version I have to flash. It's just that every version seems to be failing.
Sorry, I wasn't very specific. Because you're on MJC, there's no way to downgrade. That's why none of those ROMs work.
You need to flash the 4.3 MJC firmware via Odin because when you flashed that MD5 firmware, it messed with the MJC bootloader, and the MJC firmware won't let you downgrade to a lower firmware.
So flashing the 4.3 MJC firmware will restore the MJC bootloader, unbricking your phone.
