i put the reset options and realized i put erase all content etc. and it takes several hours, i need to do a factory reset on itunes instead. now it’s on the black screen with loading circle. how can i undo this or do i have to wait till it finishes.
Since the iPhone appears to be stuck on black screen with loading circle. You need to perform DFU Mode Restore with iTunes on computer.
erase all content and settings is the factory reset it will wipe the phone to factory condition
