I was trying to be nice to my dad and update his iPhone 6s (he hasn’t updated in 2-3 years) but when I went through the process and cleared the 750MB of space for the update I plugged it into my laptop and everything was going fine until it stopped not even half way through the black Apple download screen and then this error appeared. I tried looking into the error but there’s no information on it in the error code guide. Please help I’m stuck.
