I have a new 3ds xl us already install gateway exploit and it runs perfect . Just this morning , i did this : "Problem: After the installation of a .cia file, you must “unwrap” the application after every boot Solution: Remove your internal SD card and Gateway Red cart. Power the system on and do a system format from the System Settings menu. Once finished, power the system down and replace the SD card and Gateway Red cart. Power the system back on and test again. " It's on gateway menu guide . I did exactly every steps and now i can't boot to gateway mode . Do i suppose to install all over again ? I don't own cubic ninja . Thank you for all your helps.
