iPhone 6 requesting a 6-digit passcode after full reset
I bought a new iPhone and was planning on keeping my old iPhone 6 as my emergency backup. I did a full factory reset on it over a month ago and today I got it out to power it up and make sure it still works which I do every few months. The Hello screen displayed and when I pushed home I got a semi-dithered passcode request screen for a 6-digit code. I entered the ONLY 6-digit code I've ever used and ended up getting locked out for a minute. Based on past posts it looks like this has been an issue since at least 2016. Any updates? Or is my perfectly good but old iPhone now a brick? Would it be possible for Apple to stop putting out new products until they get the old glitches like this and songs magically disappearing during backups fixed?
