Hi guys, i was trying to upgrade my New 3DS XL to Luma 8.1 ( i've been using 7.1 ), i'm having problems at the very begin of the upgrade, when it says to boot the device while holding Start button it doesn't show Luma3DS chainloader screen, but instead takes me directly to the nintendo home screen. Booting the device while holding SELECT instead bring me to the menu where you can choose "Show Nand string" bla bla etc etc. What am i doing wrong? I downloaded 2-3 times every file needed but it still doesn't work, anyone can help me?
