Chosen Solution

the bottom screws to open my 6S are completely stripped and I have tried multiple methods to fix this. I have tried rubberband bigger bit superglue and use a flathead. None work. Please help

You could try drilling them out if you have tried everything else.  There has been a few times over the years when I have forgotten to remove the pentalobe screws. The brackets on the screen break off at the base and I just glued them back on when reinstalling the screen. If you are doing a screen repair all the better.
