Hello guys! I searched everywhere and I couldn´t have a proper answer: can someone help me? I have a New 3DS XL, firmware 9.0. I use GW for a while and I lost the blue card. I´m trying to use DS roms with 2 another flashcards: Acekard 2i and a R4 SHDC Dual-Core (website www.r4isdhc.com). Both only shows black screens... I tried use the CIA for updating the NAND to use older flashcards but with no avail. Can I upgrade to any further firmware to downgrade to 2.0? I´m afraid of bricking it! If someone can give some leads... Thx!
