Home button stopped working after charging port replacement


Recently, I replaced the charging port on an iPhone 7. I disconnected the battery, then the screen, and from then just continued disassembling the logic board.

The repair went well, and the charging port now works. The only problem is that now the home button does not work.

I am frustrated because I did not do anything to the screen, only disconnect it. I’ve had to use a JC home button (bluetooth version) as a temporary fix.

Do you have any idea of how I could fix this?

Thank you!

The iPhone 7/8 series have a very inconvenient bend on the Home Button flex. It’s really easy to tear the flex, either near the logic board connector or at the 90 degree bend before it sneaks underneath the LCD heat shield. You have to be careful when you lift the screen off the first time but also anytime the flexes are connected and you have the device open.

The other area that is easily damaged is the connector on the Home Button itself and the opposite connector on the short flex that runs underneath the heat shield.

The long and short of it is that there are multiple failure points. You will need to carefully inspect the Home Button and flex to see if there is any damage. Magnification here will help.  Look for tears to the flex or any physical signs of damage. You should also check the connector to insure none of the pins are damage or that there isn’t any debris.

keep in mind if you insert an isesamo into the usual spot on the iphone 7/8 series, bottom left of screen, the home button flex cable is right there and is very easy to damage accidentally. I usually go in from bottom right on these particular devices.
