I must be mad, lol. Just flashed my French 930 with the CV UK unbranded firmware. It really doesn't make any difference but being a geek I wanted to do it. The 930 is an RM-1045 and the firmware codes are here: Product Codes Nokia Lumia 930 Rm-1045 - Product Codes Nokia - Nokioteca [Nokia] Forum - I have the white 930 so my product code for the UK unbranded firmware is 059W025
