Hello, I have an iPhone 6 Plus, that suddenly not working anymore. I have a black screen and see nothing. The screen is working well, when I put my iPhone 6 Plus to iTunes I get a iPhone in restore mode. I dont see any screen here, but when I click restore the apple logo appears and then I got after a while iTunes error 4005. What can be the problem? Thanks. UPDATE: After I cleaned my dock connector I got iTunes error 4014.
