I have offloaded all of my unused apps, it’s showing I am only using 55 of 256 GB of my iPhone X. I’m currently running iOS 11.3.1 and would like to update so I can use the Chase app and jailbreak again. I have tried plugging my phone in on WiFi and still getting this error, any suggestions? I currently have no access to a desktop, but could potentially use my parents if I absolutely have to although I am currently injured so this would be difficult. Thanks!
