I've had a Hyrule n3DS XL with a broken B button for quite some time. I sent it in last November right before the 1 year warranty expired, bringing my warranty back up to 3 months. Sent it in again in December because the circle pad came back scratched. Now the B button is failing again, and I'm on my last month before the warranty dries up. However, I installed cfw right after receiving it back from the second repair. If anybody has any experiences to share about sending it in with cfw, is it okay? Any precautions to take use, such as using the Kecleon patch? Or should I just do a fresh uninstall of a9lh and reset, transferring my current progress to another n3DS before sending it in again? I kinda want to just remove everything suspicious and keep a9lh on the system (since 11.3 exists), but if the repair center actively checks that, I'll just do a full uninstall. Thanks!
