Try using the original firmware's ROFS1\sys\bin\aknskinsrv.dll (in ROFS1 and remove it if it exists in ROFS2, 3 or UDA [C:\]) and change the definiton path in ROFS1 to C:\effects or E:\effects\ and then flash it using Update SW without your UDA.
There is no need to reboot to change effects; you only have to turn them off, replace and then enable them again to change them.
