iPhone XS Max unable to verify or install update 18.7.7

Unable to verify/install latest (April 1) iPhone update 18.7.7 on iPhone XSMax. Do I wait or worry? I tried restarting the iPhone and “unablt to verify” message persists. This is the first time i have not been able to update. Is there a update server issue because I also got 2 server error messages “too many requests” when trying to post this query. 😬

I followed instructions on Apple support site and deleted the 18.7.7 update. Re downloaded it and it still give me the same error. 🙅

“If you still can't install the latest version of iOS or iPadOS 

If you still can't install the latest version of iOS or iPadOS, try downloading the update again:

  1. Go to Settings.
  2. Tap General.
  3. Tap [Device] Storage.
  4. Find the update in the list of apps.
  5. Tap the update, then tap Delete Update.
  6. Go to Settings.
  7. Tap General.
  8. Tap Software Update and download the latest update.“

Perhaps an initial attempt on this type of failure might

include use of Feedback to Apple Support form online

and to clarify your experience fill in all blanks carefully.


Feedback - iPhone - Apple

//www.apple.com/feedback/iphone/


Instructions will appear in your local language, while

my form was in english, for a US version submission.

.Also found the download in iPhone (XR) and deleted.


And before you send, a final idea to remind end users:

"Please read Apple’s Unsolicited Idea Submission

Policy before you send us your feedback."

I have the same issue since yesterday. I am in USA. No VPN. I tried connected to wifi only and celular only, both give me the same message.


I have deleted the downloaded udate file, restarted iPhone, but it does not fix the issue.


Tried to update using iTunes and it also fails but with another message.


It is able to download the update file, but when it tries to verify the update it fails. No matter how many times I try it.
