I don't know if this is the right place to post so you can move to where it needs to be "How do I find out the secret id from an event Pokemon? Anyone have an idea on that?"

Hello. Nice to meet you all.

I looked through every thread and none of them didn't really answer the questions that I have. My questions are down below. 1) When I try to import my save data for Y it doesn't seem to work. Is there something I did wrong? 2) What is a .ekx file for? This is probably a newbie question haha... 3) My current firmware on my 2DS is 10.3.0-28U and I tried to trade with my sister but an error popped up. Is there something I need to do first? If the questions I asked sound dumb, you can just disregard them and lock this.
