I just bought a New 3DS Japan with the preinstalled arm9 and Luma3ds from videogameshop in a Asia Country. The language has been changed to English. I can play pre-installed games from the menu. I see there are Soon2 and FBI's icons to manage the CIA files..etc However, i check my n3ds setting and see the firmware running is 11.0.3U. Should i downgrade it to 10.6/10.7 to be secured from future blocking from Nintendo?How? Can i use NTR CFW on the current stage of my N3DS (FW 11.0)? How can i protect my self from getting my N3DS bricked? Sorry for the noob questions!
