I've created my nnid for usa and had trouble the first time because i entered ny as second, it somehow worked removing ny the first time.
After testing it out i re-created all my work to test if everyone can repeat my steps, but it didnt work. After messing some time with it,
'Internet' was gray and not green and i received 005-5602. I called yesterday Nintendo support and told them i'm having trouble
using eShop, the operator was very friendly and told me that my linked console is not for usa usage and should check my region.
The process changing region is easy for me, but requires a donor because of rsa checks and knowledge not to mess everything up.
I don't know if online play works for JP/iQUE/TWN with swapped region or will result in bann! Someone i know from different board
owns JP 3DS, lives in EUR, and has trouble playing non JP roms online and receives 003-0399. Switching region removes Internet
agreement and you have to accept them again. If your Firmware doesnt offer the region in your profile, you receive the same
answer i got from the operator.
Currently i'm not banned, original region works fine and eShop still works.
1. swapping region will ONLY work without eshop
2. You might need to patch every game to region free IF online gaming is possible
At the moment, i'm not sure if its good to offer a 'How to switch region' as it might end up in banns,
bricks and more trouble if ppl try to fidle with eShop like it happened for sony and ps3. Taking this
in consideration, i don't want to give support for it.
The only thing i can say, part of the information is already out there without me or cearp.
