iPhone disabled, "connect to iTunes" happened so i came to apple for support and i followed all of the steps but my phone screen went black yet lit, instead of the iTunes logo screen popping up. However i was able to proceed with the steps because my computer and iTunes did have the exact same pop up question asking to restore or update the phone. i clicked restore but when the screen said it would be downloading software and to wait around 15 minutes plus, my screen stayed lit yet black and i sat and waited by the phone and compute for more then 155 minutes but the iPhone would just restart up after being lit black for a while and go back to original disabled connect to iTunes. i even looked up videos on youtube nut i didnt find anything about a black screen while doing all of the steps. the phone is an iPhone 6 plus. it is not damaged. its my husbands old phone we saved for our son but his friend changed his passcode without my sons knowledge and my son didn't know about too many attempts causing his phone to disable. trying to do this but its not working for some reason. is there suppose to be something on the computer screen showing iTunes is downloading the software or just the phone as i saw in the youtube videos. my phone stays all black but lit. not iTunes image as seen in these steps with images. i am wondering why this is happening and how i can move forward in some way to restore the phone.
iPhone 6 Plus, iOS 11.4.1, unsure the iOS
