What does "unknown error occurred (-54)" mean?

It keeps popping up when I add songs to my phone. Also, when the songs are transferred over to my phone, it gives the wrong album cover. It gives me a different one every time too. Can anyone help with this?

iPhone 5c, iOS 7.1.2

See Unknown error (-54) with iTunes Library | Techyv for possible solution. If you cannot solve it then you should restore it:


Placing your device into recovery (DFU-Device Firmware Upgrade) mode:


Follow these steps to place your iOS device into recovery mode. If your iOS device is already in recovery mode, you can proceed immediately to step 6.

1. Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the

other end of the cable connected to your computer's USB port.

2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds

until the red slider appears, then slide the slider. Wait for the device to turn off.


* If you cannot turn off the device using the slider, press and hold the

Sleep/Wake and Home buttons at the same time. When the device turns off,

release the Sleep/Wake and Home buttons.


3. While pressing and holding the Home button, reconnect the USB cable to the

device. The device should turn on. Note: If you see the battery charge warning,

let the device charge for at least ten minutes to ensure that the battery has some

charge, and then start with step 2 again.

4. Continue holding the Home button until you see the "Connect to iTunes" screen.

When this screen appears you can release the Home button:

5. If necessary, open iTunes. You should see the following "recovery mode" alert:

6. Use iTunes to restore the device.


If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.

Additional Information:

If you have a problem getting into recovery mode then try: RecBoot: Easy Way to Put iPhone into Recovery Mode.

Note: When using recovery mode, you can only restore the device. All user content on the device will be erased, but if you had previously synced with iTunes on this computer, you can restore from a previous backup. See this article for more information.

I read on another thread that the problem might be related to file permissions and I've noticed some funny permission settings on a few on my music files recently - in particular I wasn't able to change any ID3 data on the files, album art or anything else.


Long story short, I changed the file permissions of all my music files to "everyone - Read & Write". Immediately after I did that, my iPod synced fine. (I have all my music on an external HD, so I just applied the permissions to everything on the drive - example below)

Hope that helps. Good luck.
