First time:
user definied mode + ignore variant in green menu -> without reboot to red update menu -> Userdefinied -> mark everything with MU in Front like MuTnrRef MuINIC and so on... when you marked everything with MU in front, then start the update (dont look for MU9411 ... only flash the others) - if version is same it doesn't matter mark it!

After Update it will tell you that MU9411 is not reach-/startable don't get in panic press something like cancel and finish the update.
------------------------------
Second Time:
user definied mode + ignore variant in green menu -> without reboot to red update menu -> Userdefinied -> now you must have there a MU9498 ... go inside and mark everything, then start the update! After that you must have the right unit again for AU3G Unit.

I've done this many times.
PS: Use original Metafile, don't mess with it and don't change something!
