So what I did on my a9lh console is, delete my eshop,format the 3ds, then do the region change part. Do I have to open the eshop again before the region change or after? Cause i opened it after. And since it's a japanese console, Im not really sure what happens when I delete the eshop account. What happened was, I blindly looked for some options until I saw an image pointing at the serial number, till Im prompted to put the serial number, and afterwards I get stucked at somepoint where I can't press home(it shows the home icon with a slash on top of it) and I hard reboot the console just to get back to home menu, then format, then region changed. Did I do it right?
