[Q] bricked tab s topic

Hey guys,
so I really messed up. I don't blame anyone besides myself.
Just seeing if you guys had any ideas that would help.
So I have a tab s t807 which is now bricked.
I did root and flash twrp which went perfect.
Since I don't use my mobile data for my tablet I decided I would flash a t805 rom
I knew it would work fine just data would be a Problem.
Now here's my mess up. I really wasn't paying much attention.
downloaded the Ironman t705 and flashed it. Huge mistake I know!
Now my tablet screen won't turn on. I can boot download mode
Can't figure out how to get to recovery.
I work for tmobile and now they don't do warranty for that tablet,
also my knox count is at one. So I can't go to samsung.
Any ideas? Thanks for the time for reading this.
