Two things real quick. One is that you should've posted this in the PKHeX thread, and secondly something that might work is one extracting it if you don't see a icon next to it and the other is changing it's compatibility mode.

Can you describe the steps you're doing please. Also yes your version is compatible.

PKHeX isn't the only software that is usable, just as long as you are saving the file correctly and the file has the valid code.

It likely will work it worked for me and I have a Persona Q 3DS XL.

The pokemon servers are likely not recognizing it as a real pokemon. A easy fix that has a fairly decent chance of working which is to trade it in a LAN and then trade it back.

When you're in PKHex and hit save as are you sure you're saving it as a .EKX which should have the file name .EK6 before you change it?

As long as your browser crashes you should be fine.

I would personally recommend trying this is may change something it may not. However there may br another fix for the current SD you have which you might want to try as well. I would tell you this fix now but I'm on my phone.

What SD card do you have? Also if you've changed the SD card that originally came with the 3DS mention that to.

It's likely a issue with the generated pokemon it's self because I personally got a Ninetails & Glaceon but when you put them in your party you get the same black screen if you hit the button to show your party or if you try and view the pokemon's summary. At the moment I've found a way to fix it but it's kinda inefficient, however the way I solved it was by trading the pokemon to my friend and then he traded it back to me and it worked. This was done on LAN however and it may take a different effect if you do it online.

I'm not really sure then, but try asking the creator.

Ahhhh I myself used 9.4 and I originally heard that you could only use 9.2 & 9.4 .

Your version is one of the two that will work. So as of now I'm not completely sure why it's not working for you.

That would be correct you may be able to receive the egg but it will never hatch.

I have two pieces of advice for you. One is that if you go into your 3DS and go into the settings and if at the top screen it doesn't say 9.0 or 9.4 then you are kinda screwed for now. The second piece of advice I have for you is to watch a video tutorial to make sure you're doing everything correctly I personally would recommend this video.
