I have a Samsung Galaxy Tab 2.7.0 GT-P3100. I would like to root it without losing my apps and stuff. I looked at many tutorials online but none of them say how to backup stuff or how to root without losing everything. Another thing that confuses me is the roms. Do I really need to install a custom rom or can I stick to the stock one? Sorry about posting in the wrong place, move it to all things root please.
