Answer to: Fingerprint Sensor no longer working after screen replacementI have the same problem. I have updated and restored the ipad with no luck. The only option is to consider another LCD. I've done thousands of iphone 6, and sometimes the cable that the home button plugs into is faulty. That's a cheap and easy fix, but another Air 2 lcd is real expensive.
Answer to: Tablet is stuck on "iconia tab".Power + volume down while lock button is in the locked position. Once tablet vibrates move lock button to unlock position, and then release the power button. Use both hands. If it gives a bootloader error in red letters, repeat the steps until it takes. This took me about 15 consecutive tries before it finally reset the tablet.
