Depend of your variant. Check your variant and search for root for that one. The most of root options dont support all variants.
As you already saw at IOROOT
page, there are links for root options for other variants.
Don't just download 1st one and try, or try random like @ac3ofS2
mentored. Check variant and root your device.
Trying things on that way can lead to brick your device.
p.s. if your device is not found, check do you have installed good USB drivers.
