[iOS 5] Unhandled Lockdown error (-15)

[Sameer Morar]

When I plug in my IPhone via USB, it does not get detected.
Upon unplugging the USB cable and re-plugging it into the computer, I get a dialog stating the following:

"Unable to mount Sameers iPhone
Unhandled Lockdown error (-15)"

Upon further investigation, the following lines appear in the syslog:

Note that a segfault is registered from upowerd and iphone-set-info.

My IPhone is a 3GS, running the release version of iOS 5.
This issue was not present before I upgraded the phone's firmware.

I do not know how to attach gdb to obtain a relevant backtraces as upowerd is invoked by upower and iphone-set-info is invoked by udev.

I am running Oneiric, with the following relevant packages:

[Shaun Burch (shazbot)]

Experiencing same issue with an iPhone4 (iOS 5.0).
Issue was not present in 11.04 with iOS 5. (Ubuntu version I was using when I upgraded iOS)

Running Oneiric.
3.0.0-12-generic-pae #20-Ubuntu SMP i686 i686 i386
UPower client version 0.9.13.

I am new to this so not sure how to get versions of the lib files but would like to help however I can.
Please advise if you need anything else.

[10111 (joachim-neu)]

It's an iPad 1 iOS 5 Ubuntu 11.10 here that's showing this symptoms.

[Jonathan M. Prigot (jprigot)]

This also occurs with my iPod Touch 4G and iOS 5. The lines logged in syslog are:

[Tomek Bury (tomek-bury)]

The segfault is an obvious bug to solve. Until then the wworkaround that worked for me can be found here:

http://ubuntuforums.org/showpost.php?p=11350062&postcount=2

It boils down to the unpair-pair sequence:

sudo apt-get install libimobiledevice-utils
idevicepair unpair && idevicepair pair

[zelegolas (zelegolas)]

this command:
sudo apt-get install libimobiledevice-utils
idevicepair unpair && idevicepair pair

Doesn't work for me. Stay with "Unhandled Lockdown error (-15)"

[John Byrne (john-realisemypotential)]

I plugged my iPhone 4 (IOS 5) into my USB (Oneiric) and got the "Unhandled Lockdown error (-15)".

I clicked "OK" to close the error.

In a terminal, I typed "idevicepair unpair" and pressed Enter.
The computer responded that the unpair had been successful.

I unplugged the iPhone and then re-plugged it into the USB.

It mounted successfully for the first time since I upgraded to IOS 5 and Oneiric.

I am a happy boy.

[John Artman (john-b-artman)]

This worked for me as well. If anything changes, I will post here.... If not, assume that in the next connection/OS boot it still works

[Hansjoerg Niederegger (hansjoerg-hansjoergniederegger)]

sudo apt-get install libimobiledevice-utils
idevicepair unpair && idevicepair pair

worked for me on second try - thx for this

[Lunique (lunique)]

"sudo apt-get install libimobiledevice-utils

For me work as well after reboot but when trying to impor foto from iphone with shotwell i got this error:
"Shotwell

cannot lock the camera:error not specified -1

Las posibles soluciones deberian ser automaticas al momento de liberar ubuntu, no es posible que funcione bien en la version anterior 11.04, y al cambiarse a 11.10 no sirva.

[Stephan Müller (megandy)]

The solution:
idevicepair unpair && idevicepair pair
and variation of it described above don't work for me. I'm using 11.04

[victorairway (michaelspencer2)]

The solution:
idevicepair unpair && idevicepair pair
and variation of it described above don't work for me either. I'm using 11.10 though

[Alan Pope 🍺🐧🐱 🦄 (popey)]

I had some success with this by deleting the contents of ~/.config/libimobiledevice and then reconnecting the device.

[Matt Marsh (marshmn)]

I seemed to have better success when my iphone was unlocked (I mean that actually on the iphone I unlocked it from the lock screen before connecting the device).

[Michael Zeltner (mzeltner)]

Matt, that did it for me. Unlocked screen then unpair && pair, plug out plug in, mounted! Thanks!

(iOS 5.0.1, 11.10)

[Tobi Blank (tobiblank)]

Same as Matt and Michael. Works for me.
(iOS 5.0.1 and 11.10)

[Avik Topchyan (topchyan)]

Matt, unlocking the phone first definitely makes the difference when running idevicepair unpair && idevicepair pair commands.
Thanks! I'm on 11.10 and iPhone 3GS with iOS 5.0.1

[John Artman (john-b-artman)]

It works with my iPod and iOS 5. But when my virtual box instance of Windows XP SP3 doesn't detect that its available. Any hints or links to other bug reports?

Cheers

John

[Paulo (pauloerweber)]

The unpair/pair commands worked on my iPad 1st Gen. Later to the commands, I removed ~/.config/libimobiledevice, rebooted the PC and only then connected the iPad (unlocked) on USB. After that, Ubuntu 11.10 was able to mount the iPad, even locked.

[almadana (almadana)]

sudo apt-get install libimobiledevice-utils
idevicepair unpair && idevicepair pair

it works for my iPod touch 3g on iOS 5.0.1

running kubuntu oneiric, I previously could see the stored pictures, but now I can load music on it with amarok!!

Thanks!

Álvaro

[GuyS (guy-stalnaker)]

New upgrade to oneiric. idevice_id correctly identifies device ID as "JimmyG's iPhone" and if I plug the iPhone4 (iOS 5) in with it in a locked state I get a dialog telling me that it is locked and should be unlocked. The instant I unlock it, I get the "unhandled lockdown error -4" immediately. idevicepair unpair/pair does not work. I get the "QueryType failed, error code -256" error. So, idevice is communicating with the device, as is the OS for I see other information collected; e.g. in the syslog are multiple entries regarding the iPhone as a USB eth device:

So, again, there is significant communication between device and computer, but the damned lockdown error persists no matter what I attempt.

I'm quite willing to support any effort to trouble-shoot/debug this issue, if someone will provice guidance on what I can provide to you. As I'm apparently not alone in seeing this -256 error (there are several reports on forums.ubuntu.com and forums.linuxmint.com and on this bug report).

This has been very, very frustrating. I saw so many reports that the latest libs in oneiric "solved" the issues that I today spent the hours necessary to backup and then upgrade to it. Only to have the exact (!!!!) same errors with oneiric that I had with natty.

[SirPecanGum (sirpecangum)]

11.10 with iPhone 3GS and same error. This works for me too:

idevicepair unpair && idevicepair pair

Unplug and plug in...

Thank you !

[R. Drew Davis (drewclist)]

The pair/unpair suggestion didn't work for me, but comment 26's suggestion to be sure to enter your pin to unlock your device before you plug it into the USB port did the trick for me. I'm running 10.10 Ubuntu and have an iPod Touch.

[WeatherGod (ben-v-root)]

Moving the ~/.config/libimobiledevice folder *and* doing the unpair/pair *and* unlocking the phone before replugging the ipod touch 4 (iOS 5.0.1) worked for me on 11.10.

[drkitty (cat-psychology)]

John Byrne's solution worked for me. Unpair device, unplug iphone, replug iphone. Thanks!

[John (human395234)]

Following the advice of #20 seems to have fixed it for me (thanks Alan). I also tried installing libimobiledevice-utils and giving the command idevicepair, which returned 'command not found'. I am using ubuntu 10.04.

[John (human395234)]

Edit: My problem did not actually involve an error message notification. Simply, nothing happened when connecting my iphone 3gs.

[Ken McLennan (ken054)]

Using iPod Touch 8g with ios 5.01. Just changed from Xubuntu Oneiric to Mint 12. Didn't have this problem on Xubuntu (had others, but device was recognized), it's only appeared now using Gnome 3.

Dmesg gives:

[237373.841464] usb 2-1.1: new high speed USB device number 4 using ehci_hcd

I think first 2 lines at plug in, third was giving mount command through Nautilus.

I've little knowledge of programming or fault analysis so I'm not sure how I can help. I've tried swearing and cursing but that didn't change the result.

[Ken McLennan (ken054)]

After reading through ALL of the comments above (instead of the first 4 or 5) I installed libimobiledeviceutils and in a terminal found that "idevicepair pair" then allowed successful mounting. Subsequent umount/unplug then automounted when plugged back in. Seems that the utils may need to "pair" the device before it will work properly.

[Falk (andreas-mockel)]

I can confirm comment #36 by Ken McLennan.
First pair manually then mount works..

[Sander Jonkers (jonkers)]

The

   sudo apt-get install libimobiledevice-utils
   idevicepair unpair

works for me. Thank you.

[BBerastegui (borjaberastegui)]

Hey, try out unlocking the iphone first.

I think its the password lock or just the lock.

Unlock the iphone and "idevicepair unpair && idevicepair pair".

None of the solutions worked for me until I tried this.

[gatortim (gatortim-1986)]

bizarre but if I connect my phone while logged in under another profile on
my PC, it mounts the phone no problem

However, now that the device (iPod Touch 4G, iOS 5) connects, I cannot delete any songs on it, nor will it let me copy any on to it. It actually uses up storage that I cannot access, even from iTunes.
