So I installed the USA firmware CIAs for 9.2.0 on my 9.2.0 EUR emunand then swapped secureinfo_A files, which created a USA emunand. I formatted the USA emunand then went through FBI to uninstall the EUR files which are no longer needed. However, everytime I do something that requires the keyboard in software other than system settings, be it in a game or the Mii Plaza, my N3DS gives me the black screen with "An error has occurred". I've tried many different region changed NANDs while deleting titles through FBI based on the 3dbrew title list to no avail. The only time I've seen this issue on the forum was on this thread: https://gbatemp.net/threads/help-request-region-changed-from-9-2j-to-9-2u-keyboard-crash.388725/ Is there any specific file tied with the keyboard that is causing the crash? If anyone has any advice, it would be appreciated.
