Well, what can you say, what goes around comes around I guess. Over the last few day I have been experiencing more and more frequent bright, white flashes on the screen of my iPhone 13 Pro Max. Of course this prompted me to do a bit of reading on the topic.
I found that this is caused most frequently by either mechanical or software damage and very occasionally by corrupted applications. This morning on wake the display went to a fixed white screen.
This issue has been around for a long time, since iPhone 6 and can, most often be repaired by connecting the phone via USB to a suitable computer with iTunes in the case of a PC or earlier Macs or the Finder in later macOS then putting the phone in DFU mode. In my case the only indication that I had successfully activated DFU mode was the appearance of the below screen in Finder because all I had was a blank white screen. On the screen that appears in Finder;
select "Update". Not Restore. Restore is a last resort method which will erase your iPhone to Factory Settings. "Update" downloads a fresh copy of the current iOS, overwrites the old copy (if it was already current) and updates the firmware of the device. This was an 8GB download in my case so it took a little while, about 30 min. Eventually my screen turned to black with the beginning of the installation accompanied by the comforting white Apple logo in the middle and a progress bar below. This process also took quite a while, another 30 min. At completion the iPhone disappeared, rather disquietingly, from the sidebar of the Finder window and a dialogue on the screen warned me not to disconnect the iPhone. After about 20 min I succumbed to curiosity and pressed the power button on the phone. The screen came on, white this time, with a grey Apple logo, progress bar and a message, "Attempting Data Recovery" at the bottom. After a further 20 min it had almost progressed to the end and when completed the iPhone reappeared in the sidebar of my Finder window.
At this point I ejected it from there, dissconnected it, entered my PIN and all appears to be back and functioning as before.
The Apple Support page mentions nothing about the "Data Recovery" process; If you can't update or restore your iPhone or iPod touch - Apple Support
From what I can find on Apple's Support pages it implies that if "Data Recovery" fails you may need to restore from a backup and goes on to describe how to do that.
For me, although time consuming (about 90 min) the process worked perfectly and appears to have fixed the problem but I have read that a number of users complain that the "Data Recovery" process got stuck or ended in a loop, whatever that means, and I wonder if they missed the "do not disconnect your device" warning as I almost did myself.
I have performed a new backup to reflect the firmware update and any other changes that may have occurred under the bonnet.
