Let your mom plug in her phone, let it update to Mango, then flash the mango language pack for Dutch: 0407 (Dansk is 0406). You have to make sure that the version of the Dutch language pack cab that you use is the same as the FW version of her phone.
It can't be that simple. I've been trying to figure this issue out for 12 hours straight now.
