Basically, I broke the home button flex on my OEM iPhone 7 screen (the part that goes from the screen to the logic board). I had an iPhone 7 screen lying around, but it's not OEM, and I want to transfer the non-broken home button flex cable from the non-OEM screen to my old broken OEM screen.
How should I go about doing this?
Thanks :)
Is this a good question?

One question, did you tear the flex that the physical home button is attached to? Or did you tear the flex that the HB (home button) attaches to just below the screen.
If you tore the flex that attaches to the physical HB, you can transfer a Non-OEM HB as many times as you want and still have no touch ID or "click to home" functionality. The HB's are serialized and without a tactical dome switch button (the home button design since the first iphone), there is no circuit running that detects your "click". Your only recourse is to seal up the phone as best as you can, take it to Apple, don't mention any efforts at repair, and pay their price. When the HB fails to work for them, they can replace/reprogram the system.
If you tore the flex that comes out from the LCD backlight plate and connects to the HB, you don't have to transfer the Non-OEM HB to the OEM screen. You have to transfer the OEM HB to the Non-OEM screen.

I think it's pretty clear that he teared the home button extension cable coming from the screen to the logic board but yeah just putting the home button to the other screen and using it would do the trick.
Well the two cables going to the mobo are LCD and Digitizer, with the force touch and HB cables integrated into the Digitizer.

I tore the HB ribbon cable connecting the screen and the logic board. The thing is, I have a perfectly fine working OEM LCD, the only problem being that torn part. Is there any way I can KEEP the OLD LCD touch screen and only replace that singular cable?

Not easily, no. That cable is integrated into the backlight and force touch panel. I imagine it’s doable it has patience, Heat, and soft tools. You could swap that backplate out completely.

Is there a tutorial for that process?

Not really as far as I know, no. I just experimented on old broken display assemblies. It works a great trick if the backlight burns out and you need to recover data. I would recommend just being very careful and going slowly. Don't get your tool under the plastic as much as you can, and there's probably a ton of adhesive along the top as that's where the backlight LED strip is. That requires just being careful. Depends on how much you really need it vs buying a new screen to try again.
