When you boot up for the first time, it will create a license request file. You upload it to the Xecuter license site and download a license file and place it on the sdcard. That's it.
To be honest, you are overthinking it. It's kind of simple to do. The most important thing is to line it up properly and soldering the anchor points. After that it's cake. Like I was saying, I was using cheap jewelers glasses and one eye closed. Also for me silver bearing core solder worked...
Installed mine today in about an hour. Soldering took about 15 min using a cheap iron and $10 jewelers glasses. But I use to install original 30 wire xbox chips, so this was easy even with my now bad vision and shaking hands.
I am trying to hack Fire Emblem Warriors on my 2DS XL, I have been trying to get it to work, but I need some extra help figuring it out. I have HEX codes, and a possibly outdated plugin, but I dont know how to implement them
