iPhone 15 Pro Max boot loop issue before & after update to iOS26
My iPhone suddenly got dark and then stuck on the Apple logo. With a reset (volume up & down & power button) I was able to get it to run again after a couple of hours. I connected it to my Mac and followed all the steps.
It had uploaded the iOS 26 version without any announcement. I thought that I would get a notification that it would happen at night as usual but it happened while I was scrolling Instagram.
It worked for five minutes, I could see the new iOS 26 icons and stuff and then - black screen, Apple logo and than the restore display with the MAC icon and the cable.
Now I tried the first steps again but got an error code The iPhone could not be restored. An unknown error occurred (9). I tried to choose reset to factory settings but got the same error code again.
I don't know what to do. My phone worked just fine up until a few hours ago. Enough storage and enough battery, I've checked everything.
