Hello, I have a Dragon Quest 2DS LL I imported from Japan and I want to change the region on it or put CFW on it so I can play US games. Currently the firmware is on 11.4.0-37J but I'll probably have to update it to the latest firmware if I want to redeem a DLC code it came with. Not entirely sure I'll have access to it once I put CFW on it and change the region but would rather try and redeem than it expire and go to waste. I also purchased an R4 B9S card for installing boot9strap. So before I proceed with just following the guide is there anything I should do or not do? Just want to make sure I don't f anything up and brick this console. Thanks.
