FAIL! SHA256 is Invalid error trying to Root

I, along with several other users, have been getting a SHA256 is invalid error when trying to do the root from this thread:

The fail comes in at the step when trying to flash the Sprint userdebug firmware in the AP slot.
I tried using different computers, cables, and ODIN and all that happened was I managed to brick my phone (but then fix it by flashing the stock ATT files thankfully)
One thing I noticed is that the firmware is downloaded as an MD5 instead of a TAR file, but I assume this has no bearing on the error.

Does anyone have any solution to this problem? It seems there are many people who have been able to acquire root, so there must be some solution available.

Any help is greatly appreciated as root access will be incredibly beneficial!

This is what the log looks like in the Odin version provided in the post:
