Chosen Solution
I dropped my iPhone 6 plus accidentally and broke the screen and home button so I had to replace them. Now when I turn it on sometimes shows the screen that says “Hello Press home to open” in different languages and some times it shows another screen with the iTunes logo that says something like “Use iTunes to restore”. I already restored it with iTunes but it keeps showing that screen. Somebody told me that the home button is bad and works as I was pressing it all time and that’s why that screen shows up. Any idea what could be happening?
To get into iPhone’s restore mode or DFU mode, you normally would hold down “HOME” + “Power”. It does make sense you would see this if the home button is stuck in the pressed position and you pressed “Power” to try to turn it on. “Press Home to Open” in different languages I believe shows up on a newly reflashed iPhone, so I am assuming when you reflashed the iPhone you wiped the phone and didn’t recover from a backup profile. If you say sometimes it shows, and other times it doesn’t, the home button needs to be replaced. It definitely sounds like it is damaged. Whether or not its just the button or the logic board, you can open it up to see how extensive the damage is.
