Ripped one of the cables on LCD, but what is it exactly?

That is the home button and 3D Touch cable.

There is nothing you can do to connect it back, but you can replace the entire display to make it work.

Currently there is a standing issue that some replacement screens do not work due to some issues of this cable/connector, but if you are careful and lucky enough, the replacement will work just fine.

Also,

DO NOT REPLACE THE HOME BUTTON.

USE ONLY THE ORIGINAL HOME BUTTON THAT CAME WITH YOUR PHONE

Remember the separate home connector cable on the 6 and 6 plus you could replace apart from the screen? This ran from the connector on the board, underneath the metal plate and to the home button flex itself. I'm assuming this is just that. Simply connects your home flex to the board itself.

It’s 3D function of the screen

hi the ripped connector isn’t the LCD and Digitizer, if the LCD and Digitizer still works, then you have then ripped the Touch ID home button ribbon flex, if you replace the entire display assembly the home button will then work again, how i know is i had the same problem until i replaced the entire screen and mine is now fully working.

Hi, this one is Touch ID cable, it can be replaced with complete backlight module and cost about $30

Here is a link to this unit on eBay

That cable appears to be the back light/home button flex. the back light has adhesive around the edges and can be carefully separated from the LCD and replaced but you will need to unsolder the contacts on the remaining flex cable to remove the old back light flex cable.

I am facing a similar issue(I guess), After a screen replacement my home button works fine, my screen works fine but there is something wrong with my 3D Touch, It just doesn’t registers a 3D Touch input(does not responds to my hard/firm press on the screen). Is there a way to test it ??

I have Apple Pro Max Lcd with broken ribbon can you repair it .please reply urgently

I have iphone 11 pro max with broken lcd flex/ ribbon can you repair it please reply urgently

Hi, I have the same problem (iPhone 7, not the iPhone 11), and found a solution, I think. I still have to try it myself, so wish me luck! I’m buying these parts, since I can’t find the home-button cable on its own: https://www.etradesupply.com/apple-iphon... and will try to assemble it … Since this is an old thread, I might not respond to it further … Oh, see also Tom Chai’s reply from 2017 (higher up) - I don’t need the touch ID, just a basic home function.

The Part I assume is The Earpiece
