I've got an N86 (RM-486). Seems as though there isn't any WLAN or 3G on it but I was thinking that at least the WLAN may be locked because of the firmware. So my plan was to try and change the produce code to that of an RM-485 N86 via NSS and then update with NSU. Is that possible or does the product code have to be from the same RM model? Thanks for the help!
