I really have to LOL each time at these kinds of threads.
Working on a $$$$ Laptop with a $1 dollar screwdriver set.
If you need to do a job on expensive gear get the right tools before you start, I have a set from iFixit, cost me I think about $20, a great toolset and before I use any bit I try out a few bits before I start using it, it must fit snuggly, if not you get the results like the OP.
I also laugh at some of the so called advise, like using Super Glue, it does not work on tiny surfaces, you need a minimum surface for it to work compared to the torque you apply.
These screws are tiny, the surface contact is most likely (far) less than a square mm and for the torque applied it is way too little.
The elastic band will do a better job than the above.
Get good tools beforehand and you won't get stripped screws!
