You are welcome.

Just S2 Classic wifi. I am unsure of any similarities or differences in the S2 cellular vs S2 classic. However, in my experience with phones and music players, the device with cellular capabilities needs to have an additional antenna or two to grab those signals. It is most likely that what you are trying to do will not work.

Not all bits/ screwdrivers are made to the exact dimensions as another. So my Y00 may be bigger in size than yours. Maybe try a Y0 from the place you ordered, or just buy the 64 bit toolkit. That is what I used in this guide.

This is my own personal watch, so I did not try to remove the bezel. The only way I can think of is by prying up on the bezel from the top. Just be careful as I do not know how or if the bezel is connected to the watch.

Just updated, sorry about the delay. The guide is now finished.
