How to Restore Touch ID of iPhone Due to Home Button Flex Broken

iPhone users might be in despair when their iPhone home button touch ID gets into trouble or even doesn’t work after replaced home button. Why? For iPhone 6 and later versions, touch ID is bonded with CPU, and the user who has replaced his home button will then lose its touch ID fingerprint function. For a long time, it is a sticky business for repair technicians to repair the iPhone touch ID issue, but actually, about 80% of the touch ID failures are resulted by damaged home button touch ID flex. REWA therefore released a video about how to restore iPhone 6/6 plus/6s/6s plus home button touch id issue by making a jumper on flex.

Restore iPhone Touch ID With Home Button Flex Reparing

Power on and test. “Unable to activate Touch ID on this iPhone”. Press Home Button, the returning function is normal.

Disassemble the phone and remove the display assembly. First of all, check the logic board connector J2118 for mouldy condition and dry Joint. Everything is fine.

Then, measure the resistance between J2118 and grounding. The value is also normal.

Take down the Home Touch Sensor Assembly and check the home button flex cable. There are obvious broken traces on the flex cable.

Preliminary judgment – Touch ID malfunction is caused by fractured flex cable circuit. We can fix the problem by replacing the fractured section with a new length of flex cable.

Pry up the back plate with Tweezer and Soldering Iron. Cut the fractured part from the flex cable with Sculpture Knife.

Scrape out the flex cable circuit. Be careful not to cut the circuit off.

Apply some BGA paste flux to the flex cable and then solder tins with Soldering Iron. Clean with PCB Cleaner after cooling.

Prepare a new Home Touch Sensor Assembly.

Pry up the back plate of the new Home Touch Sensor Assembly. Cut a length of flex cable from the new Home Touch Sensor Assembly (allow for some adjustment in length of the cut cable).

Fix the newly cut cable with double-sided adhesive. Then, scrape out the newly cut flex cable circuit. Be careful not to cut the circuit off.

Apply some BGA paste flux to the newly cut flex cable. Then solder tins with Soldering Iron. Clean with PCB Cleaner after cooling.

Cut out the excess parts of the newly cut flex cable. After that, apply 460 Glue to the bonding part and adhere the two cables carefully. Pay attention to the aligning position.

Once cables are fixed, apply some BGA paste flux and solder flex cables with Soldering Iron. Be careful with bridging and disturbed solder condition.

Clean with PCB Cleaner after cooling. Remember to check the circuit for bridging and disturbed solder.

Get the Home Touch Sensor Assembly mounted on the screen. Then buckle the display assembly to the logic board.

Power on and run Touch ID function test. Touch ID back to normal.

Take down the display assembly after test and take out the Home Touch Sensor Assembly. Prepare another length of cable. And then adhere the cable to the previous bonding part.

To further secure flex cables, solder with Soldering Iron. And then secure the back plate with Glue carefully.

Get the Home Touch Sensor Assembly mounted on the screen. Buckle the display assembly to the logic board. After that, power on and test. The phone works with normal Touch ID function.

Step 1:

iPhone 6s got water damaged. Try to start it up, the phone can not boot normally.

Step 2:

Take apart the phone and connect the phone with DC power supply, we can see that the logic board comes with heavy current.

Step 3:

Take out the logic board. We can see with naked eyes that the logic board is mouldy. Let’s run cleaning with PCB cleaner at the beginning.

Step 4:

Tear off the shield sticker and remove the CPU shield plate with hot air gun.

Step 5:

Since welded junctions of baseband shield plate come with high melting point that can not be removed by hot air gun easily. Remove the baseband shield plate with cutting nipper.

Step 6:

We can see it clearly that areas under the shield plate are also water damaged. In this case, brushes are helpless for thoroughly cleaning. So continue the cleaning process with ultrasonic cleaner.

Step 7:

Pour adequate PCB cleaner into the ultrasonic cleaner and put the logic board in. Power on and get the lid on.

Step 8:

Five minutes later, switch off the power supply and take out the logic board. After that, Leave to rest for 5 minutes.

Step 9:

Check cleaning effect with naked eyes. Then check with microscope again. The logic board looks great after the ultrasonic cleaner process.

Step 10:

Water damage also caused corrosion of rear camera connector. So we have to replace it with a new one.

Step 11:

Apply some BGA paste flux and take down the damaged connector with hot air gun. After that, clean with PCB cleaner and apply some BGA paste flux again. Then solder the tins with soldering iron. Once finished, clean with PCB cleaner. Again we apply some BGA paste flux, align and install a new connector and then clean with PCB cleaner for the best effect.

Step 12:

Once rear camera connector replacing finished, connect the phone with DC power supply and boot with startup signal triggered by tweezer. Booting current displays normally.

Step 13:

Assemble the phone. Connect with the original screen and power on, the phone go with no display.

Replace with a new screen and power up again. iPhone boots and works normally.
