You can try and install a CV ROM which stands for Country Variant, it will look like this in the list > 059R071 RM-821 VAR EURO1 GB CV RED , you need to choose the right device color only.

Also i was thinking maybe there are some issues for your variant introduced with GDR3 or Lumia Black, that's why i was thinking that flashing with a different ROM may resolve you problem.
