The other day I replaced the power button cable and volume button cable of my iPad Air 2 due to the microphones and power button being faulty. In the process of removing the screen, I pierced the LCD in a few spots. This rendered the screen unusable, so I ordered a B stock replacement screen. I received the replacement screen today and managed to get the home button moved over and everything reconnected. The power button works. The up volume works, but the down volume does not. The microphones still don’t seem to work, Touch ID still works. However, every few minutes, the iPad reboots itself. I haven’t timed it, but it seems to be happening pretty regularly. I don’t know if I have a short or if perhaps the battery isn’t fully connected. It seems to be charging fine. Any ideas what the problem could be? Thanks.
This could be a replacement parts quality issue. The button flexes could be defective or damaged (they are easy to damage). Hopefully you haven’t sealed the device before doing final test. You’ll want to remove the Volume button flex and inspect it closely for tears or connector damage. I would do the same for the Power button flex. As for the initial reason you did the repair, did the microphones fail out of the blue or was it following a drop, repair attempt or contact with water?
I have had this issue a couple times with the iPad Air 2. One of the methods to fix this is to do a full DFU restore. Im not sure why this works but it has done on several occasions. Let me know how you get on. https://www.hardreset.info/devices/apple…
