No bootloader, instead says "Downloading, Do not turn off target!".

[AC Question]

So i'm trying to unlock my bootloader, I found a way and saw I had to boot into bootloader, instead it showed "Downloading, Do not turn off target!" with text in the top left talking about Odin. Long story short I gave up and went to sleep, the next day (today) I decided to boot into recovery (not custom recovery, default) and clicked on "boot into bootloader". Last time I did this it showed the bootloader, it showed the android lying on it's back with its front opened. But then it just went to "Downloading, "again.

I have an Samsung Galaxy Tab A Rooted (Includes Busybox) 5.0.2 Lollipop Stock Touchwiz.
