iOS 17.4 update caused screen to stop working

Did you try to connect the iPhone in Recovery mode and restore it, as explained in this article?

If you can't update or restore your iPhone or iPod touch - Apple Support

Are you using the original Apple USB cable that came with the iPhone?

Update:

• Took 3 Hours for the Phone to finish doing a complete Reset
• 1hr to Restore from Cloud Backup
• All Authentication Providers are gone (very painful for me to reset up)
• Lost All Apple Pay Cards - With one only being a Virtual Card with over $100 Credit which is gone!!
• Tickets stored in my Wallet for a future Event have also GONE, so no idea on how to get them back.

So Apple, not only did it cost me a time, but appears its to be financial Loss.

Please keep my experience in mind before going down the DFU path, but yes the phone Screen is at least working.

Exactly the same issue:

• Did the Security Update (as I normally always keep it up to date)
• Upon Restart after update, Touch Screen No longer working.
• Plugged into Computer to do a DFU, hoping a complete Factory Reset will resolve the issue.

But as someone pointed out, routine security update, should'nt have ended up in needing to do a complete factory reset. Hopefully the future updates will address this issue so more users are not in the same situation.

Anyone find a solution to this? Wasn't planning on having to factory reset my phone because of a routine security update.
