Hey @Gavo2002 ,
in order to successfully update the phone software, you will need to have at least 50% of the battery left, a strong connection to a Wi-Fi network, and enough free storage. Is that your case? If so, what exactly message did you get when you attempt to do this?
In this case, we would suggest contacting our Support Team to get a repair arranged for you so our colleagues can update this. Find their contact details here: https://www.samsung.com/uk/support/service-centre/
