Can't enter download mode on Samsung Galaxy Pro 12.2 SM-T900
Following different tutorials on how to root my device, they all begin with instructing me to enter "download mode." They all seem to say that I need to press Power+Volume Down+Home and, when the warning screen appears, press Volume Up. Well, I hold down Power+Volume Down+Home (I check a video to make extra sure I was holding down the correct buttons) and all that the device ever does is continually display the initial splash screen, the reboot again. If I let go, the device goes into "manual mode" in which it prompts to reboot, update the device or factory reset it. Am I missing something?
Sorry, I looked at a few articles and could not find a solution.
