Not sure what happened as I though I already posted this, now I am being asked to come up with a name to post by??? Anyways I just let my tablet S7 (aka SM-T870NZKXAR) update on this last Sunday. Next thing its stuck in some kind of loop going from a screen with S7 tablet blah blah blah, then a screen with just "SAMSUNG," then a black screen which I assume is it turned off? I tried customer support, no help and no place within 100 miles to take it. So then I try holding different keys at different times in the loop... NOTHING. Tablet stuck in loop until battery died. Next someone said something about **** and so I downloaded it. I have no clue what I am doing now, but the tablet is just a brick at this point anyways. I don't know how to use the software and started it; nothing happened so I figure it wasn't going to work. Then I try holding the power button, up volume and place my thumb on the area where the home button is displayed on the tablet, and I get some menu to show up with items like logs, restart, wipe cash, etc... I see where there is an option to install firmware. Great? So now I am waiting for a firmware file to download from god knows who on the internet, then I guess I try to install it? BTW I couldn't find the firmware anywhere to download on samsung web site. I guess if it doesn't work then I am out nothing as it doesn't work now anyways. I know that if I can't get it to work, I will never buy a Samsung ever again! I'm getting too old for this ****!
