iPhone 6 glass is shattered ¶ 

Oh no! Your iPhone's glass did not survive your unintentional drop test!

Broken front panel ¶ 

Take a deep breath and see if your iPhone will turn on and operate normally. In most cases, the iPhone is still functional but now a cosmetic disaster. Unfortunately, the iPhone 6 front glass and LCD are fused together and must be replaced as one piece.

You can purchase a new display assembly here.

The guide to replace the iPhone 6 front panel assembly can be found here.

iPhone is frozen or unresponsive ¶ 

Even after furious button mashing and screen smashing, your iPhone 6 doesn't respond.

Restart iPhone ¶ 

Sometimes all it takes is a restart for the iPhone to become responsive again. To restart your iPhone when it is unresponsive, press and hold the sleep/wake and home buttons until the Apple logo appears (~10 seconds).

Very low battery ¶ 

It is possible for an iPhone to become unresponsive if the battery drops to an extremely low level. Plug the iPhone into your computer or wall charger and allow it to charge for at least 20 minutes before using it again.

iPhone 6 will not charge ¶ 

Plugging in your iPhone 6 does not bring it life.

Bad cable connection ¶ 

Check the USB cable for damage and dirt, especially at the ends. Then try using the wall charger, as this will provide greater power input than the computer/USB.

Broken charger or USB cord ¶ 

Try using different chargers and different wall outlets to see if there is a problem with your charger, cord, or wall outlet.

Obstructed/bad lightning connector ¶ 

Inspect the Lightning connector at the bottom of the iPhone for dirt, lint, and damaged pins. Clean out the connector very carefully with a tooth pick or soft toothbrush. If the lightning connector is broken, you will have to replace it.

A new lightning connector can be purchased here.

The guide to replace the lightning connector can be found here.

iPhone will not turn on ¶ 

You cannot get your beloved iPhone 6 to turn on.

Drained/dead battery/bad charging port ¶ 

Plug your iPhone into your computer or wall adapter to charge. If the phone does not charge when connected, the phone likely has a dead battery or a bad charging port. Replace the battery (using this guide here) with a partially charged one and see if it will turn on. If not, then it can be a power button or logic board issue. If it does turn on, plug it in and see if the charging indication comes on. If the phone says it is charging, then the lightning connector works, and the problem is either the battery that was removed or it is the logic board.

Bad power button ¶ 

The button may have lost its click. If this is the case, plug the phone into the computer and let it charge, and see if that will get it to turn on. If the phone turns on and has power, then there might be a problem with either the power button or the power button cable.

You can investigate the power button using the guide here.

You can investigate the power button cable assembly here.

Bad display ¶ 

It is possible that it appears nothing is happening because the display is bad. If the iPhone sounds like it is working properly but nothing is visible, it is possible the display is bad and must be replaced. Unfortunately, the LCD and glass panel are fused together, and must be replaced as one unit. An easy way to test this is to turn the phone on and listen for a sound. Also you can move the mute toggle switch back and forth to see if it vibrates. If it vibrates or you hear a sound but nothing displays on the screen, then that is most likely the problem. Try replacing it to see what happens.

You can purchase a new display assembly here.

The guide to replace the iPhone 6 front panel assembly can be found here.

Bad logic board ¶ 

If nothing else works, your logic board is probably bad and needs to be replaced. Now it is time to either replace it or diagnose if and what components are bad on the board and replace them, using microsoldering techniques. That is a whole 'nother beast!

If you have interest in chip level repair, you can start your investigation here!

"This accessory is not optimized for this iPhone" message ¶ 

An error message appears as if you have connected an unsupported accessory to your iPhone

Obstructed/bad lightning connector ¶ 

Check the Lightning connector at the bottom of the iPhone for dirt, lint, and damaged pins. Clean out the connector very carefully with a tooth pick or soft toothbrush. High concentration isopropyl alcohol (at least 90%) and a cotton swab should be used to clean any debris that does not come off with a tooth pick or soft toothbrush. If the connector is broken, you will have to replace it.

A new lightning connector can be purchased here.

The guide to replace the lightning connector can be found here.

Dirty or corroded logic board connections ¶ 

After an iPhone has been submerged in a liquid, there may be some corrosion or debris on the logic board connections that cause this error message. Remove the logic board and clean all of the contacts with a soft cotton swab and high concentration isopropyl alcohol (at least 90%).

The guide to remove the logic board can be found here.

Weak or lost wireless connections ¶ 

You have trouble connecting to a wireless network.

Dirty antenna grounds ¶ 

If your iPhone has been disassembled before, it's possible that finger oils were left on the grounding locations for the Wi-Fi or Bluetooth antennas. These oils will cause grounding issues for the antennas, which could lead to a weak signal or no connectivity at all. Be sure to clean all grounding points with an electronics cleaning solution before reassembling your iPhone to prevent grounding issues.

No audio or distorted audio through speakers or headphones ¶ 

Your iPhone 6 turns on and appears to work, but when you plug in headphones or speakers, the audio doesn't play properly.

Bad headphones/speakers ¶ 

It's unlikely your headphones or speakers are bad, but it's worthwhile to eliminate these as the source of your problem at the beginning. Try your iPhone with different sets of headphones and speakers just to make sure that the problem is with the iPhone and not an external device.

Bad audio jack ¶ 

The most likely cause of audio output problems on iPhone 6 is a bad audio-out jack. If you have determined that the problem does not lie in your external speakers, you should replace the headphone jack. The headphone jack is part of the lightning connector assembly, and the entire lightning connector assembly will need to be removed in order to replace the headphone jack.

The guide to replace the headphone jack can be found here.

A new headphone jack can be purchased here.

Touch ID nonfunctional after replacement ¶ 

Following a home button replacement, Touch ID features stop working.

iPhone is paired to the original home button assembly ¶ 

As a security feature, your home button's embedded Touch ID fingerprint sensor is uniquely paired to your iPhone's logic board at the factory. If the original home button assembly is replaced, damaged, or disconnected, Touch ID features will cease to function.

Restore iPhone 6 ¶ 

Your iPhone is behaving erratically or displays the text "Use iTunes to restore" on startup

Corrupted software ¶ 

It isn't often that Apple gives specific directions about how to fix your problem! Restoring the iPhone 6 will erase everything on it, so make sure everything on the iPhone 6 is stored elsewhere prior to restoring. To restore, connect your iPhone 6 to a computer with iTunes installed. Click "Restore" on the iPhone 6 summary page (click on your iPhone icon on the left menu to find this page). Follow the directions to restore. If your iPhone 6 displays the text "Please wait. Very Low Battery," leave it plugged in. This charges the iPhone 6 enough to be able to restore. If the iPhone 6 hangs on this screen for long periods of time, you may need a new battery.

Force restore mode ¶ 

If your iPhone 6 is hanging with an Apple logo, or exhibiting some other software problem that prevents iTunes from recognizing it, you can force it into recovery/restore mode and then use iTunes to restore the software.

If the device is powered off, plug one end of your USB cable into the iPhone 6 and leave the other end disconnected. Press down on the Home button, and keep holding it down while you plug the USB cable into your computer. After 5-10 seconds, you should see a "Please Connect to iTunes" image on the iPhone 6, and iTunes should prompt you to restore the software; follow the prompts and the instructions given above.

If the device is powered on, hold down both the power and home buttons until the device reboots and displays the "Connect to iTunes" image (generally, 5-15 seconds).

Error logs ¶ 

Error 1 or -1 ¶ 

Errors 1 and -1 are presented when the phone doesn't finish restoration. This is likely due to problems in the phone's hardware. This problem can often be mitigated by updating iTunes and the OS of the computer that the phone is connected to. r

Error 1015 ¶ 

Message "The required resource can't be found."

Reasons:

- Your version of iTunes is out of date. Get the latest version of iTunes, then try to update or restore again.

- Your device has a beta version of iOS.

- Downgrading - trying to install an earlier version of iOS

- Jailbroken device - hard reset it before update

iPhone has water or liquid damage ¶ 

After an accidental spill or a drop in the sink, your iPhone no longer works correctly.

Liquid damage mitigation needed ¶ 

As soon as possible, perform the following:

  1. Immediately remove the iPhone from the liquid (if safe to do so). Minimize the length of time your device is in contact with liquid to prevent corrosive damage.
  2. Turn the iPhone off. (If it was off already, do not turn it on.)
  3. Skip the rice. Contrary to what you may have heard, rice is not an effective or lasting fix for water damaged electronics.
  4. Open the iPhone and disconnect the battery. (See your iPhone’s battery replacement guide for the correct procedure. You don't need to completely remove the battery; simply disconnect the battery connector from the logic board.)
    • Liquid damage may complicate disassembly. Beware of cables and connectors that may be "adhered" to other components in unexpected ways.

At this point, inspect the interior of your iPhone and try to determine the extent of the liquid damage.

  • If your iPhone's interior looks completely dry:
    1. Whew! You may have dodged a bullet. Check the water damage indicators, look around the ports and SIM card tray, and inspect the battery connector carefully for signs of liquid or corrosion.
    2. If you notice any sign of liquid intrusion, skip to the next section below.
    3. If everything looks bone dry, you might not need to do anything further. Give your phone a couple hours to air out, re-connect the battery, power it on, and test all functions. If you notice any problems, continue to the next section below.
  • If you see only a little liquid inside the phone:
    1. Follow the rear case replacement guide to begin removing components.
    2. As you remove each component, check it carefully for signs of liquid or corrosion damage. Wipe any liquid and/or corrosion away carefully with isopropyl alcohol and a clean, soft nylon brush, such as a toothbrush, and allow it to air dry.
    3. Continue disassembling until you no longer see any signs of liquid intrusion.
    4. When all components are clean and dry, re-assemble your iPhone with a new battery.
      • Do not attempt to re-use a battery that has been in contact with any liquid.
    5. Power on your iPhone and test all functions. If you notice any problems, continue to the next section below.
  • If the interior components are mostly (or totally) covered in liquid:
    1. Follow the rear case replacement guide to take your iPhone apart completely.
    2. Clean each component, cable connector, and socket carefully with isopropyl alcohol and a clean toothbrush.
    3. Submerge the logic board in isopropyl alcohol (or use an ultrasonic cleaner, if available). Allow it to soak long enough to loosen hardened residue, and to displace any remaining water or other liquid.
      • Use the toothbrush to scrub visible corrosion and residue from the logic board. Clean all connectors, chips, and fuses.
      • Repeat cleaning if necessary, or if traces of residue are still visible.
    4. When all components are clean and dry, re-assemble your iPhone with a new battery.
      • Do not attempt to re-use a battery that has been in contact with any liquid.
    5. Power on your iPhone and test all functions.
      • For any particular function that fails, replace the associated component with a new part, and then re-test.
      • If problems persist, a board-level repair may be necessary. We don’t yet have comprehensive guides for board-level repair, so you may wish to consult a microsoldering specialist for more options.

Hello my iPhone 6 speaker jack works great, but I cannot hear the phone ring 2 feet away from me, what would you suggest? Bob

My iphone 6+ recently started displaying thin white lines down the right half of the screen. Everything is functional when this happens. However, if one smacks the phone, they go away temporarily. After, it starts to act incredibly strange: typing on its own, moving screens. Does this sound like a loose cable?
