Mobile Update - Help

[MargoTester]

My iPhone 5 was updated overnight to IOS 15.8.3. I now have a pop up telling me this with OK under a line I've tried to click on this but nothing is happening and phone is completely locked. Any ideas would be appreciated.

Have you rebooted it ?

[MargoTester]

Yes switched it off and on

I think there are factory type resets you can do, but we'll wait for a more informed answer then.

They usually ask for PIN code to be entered after an update

Just a thought do you mean IPhone 5 or 15. The 5 might be obsolete

[calmck]

The iPhones 5 and 5c are considered obsolete by Apple. The iPhone 5s and iPhone 6 both run iOS 12, for which Apple issued a security update in January 2023. This update was issued for those few devices that don't support iOS 15.Jul

OH has just fixed it! Apparently he held down volume down button and on/off buttons simultaneously, the Apple logo appeared and and that cleared it. Thanks for trying to help. I suppose I'll have to think about getting a new phone at some point but I only really used it for WhatsApp and google
