When we use fingerprint to press the iPhone home button for unlocking iPhone 6, it's failed, the fingerprint won't unlock iPhone. How to repair iPhone 6 fingerprint failure? Get latest solution here!

Disassemble the iPhone by phone opening tools, remove the iPhone motherboard. Use Digital Multimeter to measure the resistance value for fingerprint socket, the data tested is normal.

Replace the fingerprint connector flex cable, we found a tear mark on the iPhone fingerprint button. Perhaps the iPhone fingerprint can't be used is caused by disconnection, we need to re-connect the new flex cable. The line inside the flex cable is very thin, total is 19 lines. This can't connect a single cable, we can only remove the flex cable to docking.

Take a new iPhone home button, put it under the Stereo Zoom Microscope, cut off from the position close to the original iPhone home button disconnection, take the end of the socket (try to cut a bit longer), we can separate the lines and lid on the original home button, there is a solder point, directly heated with the QUCIK 861DW hot air rework station, and then pry it with the blade.

After separating the iPhone home button, we can cut off the fingerprint from the disconnection place, scraping fingerprint cable must be very careful, pay attention to the direction cannot be blown back.

We've better find some bad home button and then scrap the flex cable to practice, the boot flex cable can also be practiced. After scraping，apply some tin on it, and then connect the new and old iPhone fingerprint flex cable.

After finish the connection, first we need to test it, if the test is successful, we can reinforce it. Cut off a small piece of discarded fingerprint flex cable, use glue to cover the docking area for protection.

After the glue has solidified, assemble the iPhone 6, and test it again, now we can use fingerprint to unlock the iPhone.

Continue to test other functions, all works good.
