Worked fine flashing a FACTORY binary firmware, but only of equal or greater version as already on the phone (no downgrade!).
I haven't tried a regular USER binary firmware, so your milage may vary.
Then tried flashing an engineering rooted boot.img converted to TAR in the AP tab but it fails every time on a G930A
Here's the log:

<ID:0/003> Odin engine v(ID:3.1203)..
<ID:0/003> File analysis..
<ID:0/003> SetupConnection..
<ID:0/003> Initialzation..
<ID:0/003> FAIL! SHA256 is invalid
<OSM> All threads completed. (succeed 0 / failed 1)

Turns out that every TAR package also has a meta-data\1.mf file which contains a signature of each file hashed with SHA256 encryption.
Dang it, if anyone knows how to generate such file please share it.

I think it was not so easy to generate those hashes because this is new security from samsung and secured by samsung
but developers can welcome this security and play with it ;)

Your're trying to downgrade your firmware.
You're trying to flash a revision 1 firmware on a revision 2 device. You need firmware that is XXU2 not XXU1

Will this Odin fix an error ext4 with system.img? I believe the error has to do with different system partition sizes by region? Or is that error something you have to abide by and repartition your device?
