Unknown Samsung Galaxy Tab 3 7.0! Badly need help!!!

Hello elders. Need one again, your help. In fact, I have an 4.2.2, 2GB internal memory, android based tablet which I want to flash cause too slow running, even after factory reset. But, that's not the first reason of why I'm posting this. ?I've tried many times to find a discussion file here on your website but never can I cause I don't exactly know which kind of tablet I have. Turned on, I can read this message "Samsung GalaxyTab 3 7.0" but if I search on google writing down in the search field that words, I always see another tablet, never the one I actually have, holding those specifications. If I go in the settings, "About the phone" at the right place of "Phone model", I can reed "N968" but if I google it too, nothing. it belongs to none of the differents varieties of GalaxyTab 3 7.0 I've googled. Can you first help me identifying which kind of tablet I have and then, help me finding a path to the dedicated discussion forum in the website so that I can benefit of development. Thanks a lot in advance. I've attached some pictures of what I've talked about. Have access to the gallery of pictures here. Sorry for the bad quality! Hope that you're seeing something. http://postimg.org/gallery/1cgvpkvro
