used this method and looks like i got downgraded. thanks,but when i go to settings to check version it just hangs at the 3ds logo on top and never loads settings. same with browser just hangs. i did get a error at end of sysupdater and it auto rebooted. but it looks like it downgraded but im thinking something didnt flash? i put a game in and it loads also.
Look like a softbrick, try redo the downgrade using another entry point like OoTHax or ninjahax if you have the game cartilage. If not, well you will have to boot in recovery and update from nintendo to the newer version sorry.
