2002F Issue

This isn’t a question more of a help for anyone else experiencing this issue, after coming across this issue when trying to reinstall an OS I found that there was no easy answer to the situation. I rung Apple support and the response was take it to the nearest Apple shop. (4hrs drive away) not good enough Apple. Especially when that area was in lockdown at the time. According to Apple this is a router issue... not an Apple issue and as far as my provider says this is an Apple issue not a router issue. Basically it will not download if there isn’t a stable connection. And some say to change the DNS settings of your router to 8.8.8.8 After spending a day trying to find a solution and failing each attempt even the DNS setting change. I went for a drive. While parked up I thought I’d try one last time. So I got spotted my iPhone and boom it worked straight away. Simple solution guys - USE YOUR PHONE AND HOTSPOT IT.
