Touch ID is no longer responsive
Let me give you a background on whats been happening...
So I have a 6s plus that has severe damage on the screen and housing however the internals of the phone are perfectly fine - In fact, the phone actually is usable and touch ID was working. (Even 3D Touch!)
However, from reading on iFixit (and I couldn't get a direct answer) it seems that from opening the iPhone and unplugging the lcd, digitizer and touch ID cables (after the turning the phone off of course) I may have short circuited the flex cable. It's quite odd because I've probably unplugged those 3 flex cables about 2-3 times before to inspect damage on the internals and the touch ID 'died' on me. I soon found out that I should have unplugged the battery before taking those out.
The phone gives me a warning that "Touch ID is not activated on this phone". I wanted to order a separate new button but I found out the original button is coded to the motherboard.
Now this is fine because I've ordered a new housing and LCD, but my question still remains, can I transfer the long flex cable from the new LCD metal shield and use that with the old button? And will that fix my touch ID?
From reading on various forums some say the Touch ID on button's mini flex cable may be fried but that is less likely. It seems the longer flex cable behind the metal shield can easily short circuit.
I really want touch ID back on this phone. It would be a nightmare to have to constantly type my password each time I need to quickly use the phone.
Finally, does anyone know what the "coupling grounding connector" does? It was somewhat bent from the external damage and I can seem to screw it back in due to the corner damage however the phone runs fine.
Here's a photo of it Coupling Ground Connector
Thank you all.
Is this a good question?
