@josemanuel87453, the guide that was being referenced was for the Honor 8, not the 8X. The author of that answer was of the opinion that they're similar enough that the 8 guide would be good enough to get you through the repair. I don't know what happened to the original guide, but here's the one currently visible on the Honor 8 device page.

To be fair, it is similar, but since an actual guide for the 8X does exist (unfortunately not on iFixit), you might as well use that.
