Ok so my issue is sorted. I found a post and someone had posted a link to a conversation CCDD (another user on here) was having. He said to set it in DFU mode and restore it as a new device through iTunes as this clears all the settings.
It's worked for me. It's up to you if you wish to try it but you're wanting to use your phone which means you'll not have anything on it. Unsure if a restore with backup will work or even the scenario I've described but I'll leave this info here for you but it's entirely your choice and responsibility if you try it lol
.
Cheers.
