Can't update phone cause I need to update iTunes, but I have the latest version of iTunes so...
I'm running Windows 8 and trying to update my iPhone 7 (from 12.4.1 to 15.2) and keep getting told I need to update iTunes first. I just deleted and completely reinstalled the latest version and it's still telling me I need to update iTunes even though checking for updates tells me I indeed have the latest version (12.10.11). I'm starting to get desperate because my phone will also not download/install the update independently and I've been trying off and on for months (nor will it transfer any of my photos or videos for some reason and I've been playing a very not fun game of trying to tediously balance my constantly almost full memory for nearly a year). I finally had the time and high speed wifi connection to sit down today to really try and troubleshoot this but I'm just hitting a wall.
iPhone 7, iOS 12
