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
