Software Update via Personal Hotspot
Using an iPhone and an iPad running iOS 13.3.1 and iPadOS 13.3.1, respectively, I would like to download and install iOS 13.4.1 and iPadOS 13.4.1 via Personal Hotspot over Wi-Fi. While there are no connection problems whatsoever, both devices—the iPhone using the iPad’s Personal Hotspot as well as the iPad using the iPhone’s Personal Hotspot—are stuck in Update Requested….
Curiously, some amount of data would actually be downloaded: When I tried the same for iOS 13.4 and iPadOS 13.4 two weeks ago, more than three hundred megabytes were received; just a few minutes ago, it was roughly half of that, I could verify via Charles that this indeed originated from Apple’s update servers, and yet, it would simply stop at some point. I have an unlimited plan, all VPN configurations are disabled, Low Data Mode is inactive, and I can visit any other website just fine.
Since this did work in the past and as recently as a few weeks ago with iOS 13.3.1 and iPadOS 13.3.1, I wonder why it doesn’t now. Any ideas?
