Can I downgrade my iphone 6 from IOS 12 to 10? [duplicate]

This question already has an answer here:

  • Can I install any iOS version I wish by picking and choosing which firmware to restore? 3 answers

I upgraded my phone to ios 12. But I want to use ios 10.

So I searched that, but I found the way to downgrade from 12 to 11 or from 11 to 10.

I tried to do with these methods but failed.

Is the reason why I failed to downgrade that I didn’t downgrade sequentially, for example, from 12 to 11 and then from 11 to 10? or that the way to downgrade from 12 to 10 is impossible?
