[Q] SGH-1497 enable screen mirroring

[phirestalker]

The wifi only model of this tablet running 4.1.2 has screen mirroring capability. However AT&T in their "infinite wisdom" decided to leave it out. I am looking for hopefully just a quick and dirty hack to enable it. Here are possible solutions in order of what I would like. I will accept any answer that get the feature, but I would like to not have to put some completely different custom ROM on it as it is for my dad and he is used to the interface as is. Thanks all for reading.

1. The stuff is all there and they just disabled it (maybe just edit a file after rooting the device)
2. They left out some files to offer screen mirroring (just copy some files over after rooting device)
3. Putting a custom ROM on (as long as I can get play store and all other normal functions)

I was thinking, does anyone have the stock firmware for the wifi only version of this? I was going to get that and get the firmware for this AT&T one and see what files the wifi version has that the AT&T one is missing. I tried searching online but it is old and all the links I find aren't there. The only model I can find is the 5113 which seems like a foreign version because all of the firmwares are from some other bloody country. I need the US version since the 1497 has the US version. Please help
