No need for anymore flashcard since installing CFW is more safer and no money paid.
There is 2 things you need to know right now, of course, about 3DS hacking.
- 3DS exploit: This is a way allow to run somethings that normally can't run such as homebrew, etc. Example of 3DS exploit are menuhax, arm9loaderhax, fasthax, etc.
- 3DS CFW: This is what you want to allow your 3DS to add more function to FW, such as out of region cart load, pirating, ETC. This one need 3DS exploit to be able to run. Example of CFW is Luma3DS. ReiNAND, Corbenik.
The choices you have now is Installing
Arm9loaderhax (A9LH) Exploit with
Luma3DS CFW. Can be done by following this guide:
http://3ds.guide/. This setting is mostly safe from removed by Nintendo. The problem is, this setting require user to hack into 3DS System files. So it has a small risk of brick. But,
if you're understand and following every step of the guide I gave you correctly. Even though you bricked, it can still be fix by hardmod.
You better do this now since your FW is mostly perfect for this. 11.3 right now is hopeless.
PS. For who concern (Not OP), I decide to drop menuhax setting since 11.3 is deadly for that setting.
