After swiping up from the hello screen, it asks for 6 digit passcode. I 1st tried the steps to remove activation lock password by hooking up iPhone to a computer & following those steps, with the recovery screen. I have gone into my iCloud account, removed all the off-line devices as instructed under “activation lock.“ That has not worked either, even though it says that it has successfully removed the devices from my iCloud account. In the history of my devices, I have only used one 6- digit code to enter my phones. Never changed, not once. After “removing devices” within my iCloud account, power cycled phone, still asking for pw, tried the only one I’ve ever had, locked phone for 1 hr. Guess the only option left is to open up a support ticket, however I have to wait until I can see the IMEI on screen, bc who keeps 2 yr old receipts or old phone boxes? Thermal receipts lose their ink anyway. Hopefully a trouble ticket will eventually fix it. 👍
