Not to sound repetitive of what others have already suggested, but there is definitely logic in re-downloading a ROM in that some downloads get accidentally corrupted in the transfer process. Hence the purpose of the md5 validity check. Also, in searching for Samsung usb drivers for the sm-t800 I came across at least 3 bundles having different drivers and quantities within them. The 1st one recognized the tablet but not Odin. The 2nd one recognized both, but Odin kept failing. Needless to say that after the 1st two bundles didn't work I thought that I had not followed the instructions carefully. That I had done something wrong, so I kept trying with those same crappy drivers again and again until someone suggested I try to download them again. I realized I hadn't tried the 3rd bundle yet. When I did, everything worked great.
In other words, never be reluctant when things fail, to try a different approach or to start all over again from scratch.
Hope this helps.
