Passcode incorrect even if it’s the correct one entered
I’m trying to update to ios14.8 / ios15 but when I entered the passcode of my phone to download and install the update, it’s not being accepted even if I entered the correct passcode. I already had 3 attempts and I don’t dare to make more. Please can someone help on this. I’ve been using the same passcode for a long time and it only had a problem now.
