Is there a difference between the SM-T315 and the SM-T310? Are they the same device and can the OEM Rom be interchanged between the two? The reason I ask is because the thread title is about the SM-T315 but the rom you are trying to load in Odin (per the image you posted) is for SM-T310. So I am wondering is Odin actually protecting you from doing irrevocable harm to your device?
If everything is OK, then try Odin 3.07. I have seen several posts regarding failed loads with Odin 3.09.
