It worked for me but I have to reformat my entire SD and start fresh, a small price to pay if you ask me!
Confirmed to work for me.
Is it safer to try and downgrade from the latest firmware or the firmware my N3DS is on (9.9)
10.3 N3DS downgraded to 9.2. Without launching FTPony before sysUpdater.
Did you guys erased 000400102002CA00.cia from the update? Kinda scared over a n3ds here...
