HELP! Bricked SM-T800 topic

I have bricked/soft bricked my sm-t800 trying to flash bliss rom. I can only boot into download mode. Can anyone please point me in the right direction for a factory image for the USA model. I cannot find it on sammobile or anywhere. I have found one xda thread with stock firmware but it fails in odin. The thread states that it does not wipe data. I cannot access recovery at all just download mode. Anybody who can help me fix my device I will make a generous PayPal donation. I literally have had my tab s for a day. I will try to return to bestbuy if I cannot fix it but i;m unsure if they will take it with knox tripped. I also cannot power off the tab my options are the powered by android boot screen or download screen.
