I am trying to root my tablet and it won't show up in My Computer when I plug it in. I have tried different ports and have tried rebooting the phone. I just purchased it 5 hours ago. I have Windows 7. I installed some Samsung drivers, but I am not 100% sure they are the ones I need (I got them from a guide).
I don't have an SD Card, but I do have 8 GBs of internal memory. I have Samsung Galaxy Tab 3 T210R with WiFi.
