Have an iphone 8 that I rarely used. Decided to turn it on a couple days ago and saw the apple reboot logo. I to restore it with my mac and the 4042 error showed up. Went to apple and they had no idea what this error is. The apple support working there told me it’s not under warranty so my options were pay $350 for another iphone 8 or toss this one. No idea what to do now.
