Hi I am on 5.121 and am just about to start using a (UCM/GSM4(2G) which is being delivered today. From what I have read I need to upgrade to a more recent firmware 7.117. I will be using a new USB/UCM module which is also coming today. Please could you confirm the steps I need to take to upgrade successfully. or let me have the link to where on the forum this question has already been answered. Many thanks Attachment: IMG_1559 crop.jpeg (Downloaded 19 times)
