Still borked this morning. I’ve just delete am re-downloading the update on the computer to see if that helps.
It took me a while to find where it’s saved in 2021 on Windows and ultimately had to find it by running a manual search for ipsw files. Turns out it’s here in case people are looking for the save location:
C:\Users<USER>\AppData\Local\Packages\AppleInc.iTunes_<RANDOM>\LocalCache\Roaming\Apple Computer
UPDATE: While I was waiting I tried to do the update on my Wifes M1 Macbook. It seemed to want to start the same 6GB download, but then said it was doing something with a countdown for a few seconds… then popped up telling me that the software on my phone was corrupt and to unplug and try again. OK then…
It is worth noting that it’s been a long time since an iPhone has been plugged into a computer (for anything other than tethering) since it’s just not needed anymore. This iPhone (11 Pro Max) has had every update as they have come out so hasn’t missed anything along the way.
By this time my Windows computer had finished its re-download so armed with that new information I figured I’d try again on this machine while the Mac downloads the full file. Plugging the phone in and hitting update started the usual dance, but then I got the disconnect chime…
Was this working? Was the phone re-booting?
Sort of. I saw the recovery mode screen for a moment before it flash over the the Apple loading screen with the progress bar with iTunes telling me that it was verifying the update…
then Updating iPhone software…
then Verifying updated iPhone software…
…
then Updating iPhone firmware???
Verifying updated iPhone software…
…
It’s been a while, but I’ve don’t remember it taking quite so long or showing so many steps along the way.
…
Your iPhone has been updated… you phone will reboot
Woooooo
…
One progress bar and an apple logo later, it’s back up and running on 14.5.1
Yay!
I’m not sure if the Mac kicked it just right to do what it needed to do? In any case, it appears to have worked. I had zero issues on my iPad that I did just before trying the phone last night either.
