My iPhone 6 has failed an update.
My iPhone has failed an update wat can I do.
Hi Bakm,
Welcome tom the Apple Community,
where some of us do our best to help each other troubleshoot.
Wondering which update failed,
and
which iOS you have installed on your iPhone 6.
iPhone 6 is not included on the compatibility list for the most recent updates.
(iPhone 6 lacks components necessary for these updates.)
Unfortunately iPhone 6 cannot be updated beyond the security update iOS 12.5.5
