The old iPhone 11 of my sister says „swipe up to reset“. Then I need to enter a pin and confirm it. After that the device starts to „try to reset“. However it always fails. I train a hard reset and restart. If I restart the phone it will be locked for 8 hours. iTunes doesn’t recognize the phone (I have only a windows pc). The phone is also deleted and removed from my sisters iCloud account. Any help is appreciated!!!
