I have Ubuntu 14.04 on my 4 laptops and IOS 8.0.2 on my 2 apple devices but cannot mount the Iphone Documents drive anymore since the 8.0.2 update on ANY laptop. I have spent 4 hours researching this issue and trying every amalgamation of:

'idevicepair unpair && idevicepair pair'

and

'unplug + unlock + plugin your phone' sequence

all to no avail. When I try to mount it I get the 'unhandled lockdown error (-256)', then a trust this computer prompt, I confirm the trust message, then I get an 'unhandled lockdown error (-3)' error. I am convinced that this is a true bug that there is not straightforward solution to yet. I've noticed from searching around that older distros are not that affected but 14.04 users are getting it the most. Anyone get anymore ideas?

I was able to fix it with libimobiledevice-utils & ifuse

Disconnect your device and install packages.

sudo apt-get install libimobiledevice-utils ifuse

Restart your system.

Connect your device to your computer and run this command:

idevicepair unpair && idevicepair pair

If you phone shows "Trust computer" messages, select "Yes". By now it should connect.

If it is still throwing error, check if there is a directory var/lib/lockdown. If it is not there, create directory and change permissions for the directory.

sudo mkdir /var/lib/lockdown
sudo chmod 777 /var/lib/lockdown

Restart your system.

Connect your device and run 

idevicepair unpair && idevicepair pair

Now You can access files from your device.

I solved the error -3 by plugin the iphone, selecting "trust computer", and then typing idevicepair pair

  • Same result on all devices. Freezes and still cannot see the documents drive. I have tried your sequence multiple times already recently and in the past – Coldstar Jan 06 '15 at 13:10

I searched for 2 hours and tried several solutions, none of them helped until finally I thought to try sudo with the unpair / pair commands and it worked instantly:

sudo idevicepair unpair && sudo idevicepair pair

The solution is simple. Use following commands and next time you plug in your iPhone it would be explored properly.

  1. Open terminal
  2. fire command sudo idevicepair pair
  3. get the <name> from message "SUCCESS: Paired with device <name>"
  4. navigate to using cd /var/lib/lockdown
  5. Confirm that ".plist" file exists by listing files using ls command
  6. remove "<name>.plist" file using sudo rm -f <name>.plist
  7. You are done

Let me know in either case for success or failure of solution.

  • Hi. At second step I got an error "Device is not paired with this host". Still I can not access the phone – ogok Feb 08 '17 at 09:09
  • Upon 'sudo idevicepair pair' I get "ERROR: Device 00008027001E70423A22002E returned unhandled error code -5". Any idea how to fix? – Seub Dec 01 '18 at 18:26
