AMDeviceValidatePairing failed

Question

While using Fruitstrap (or some other tools which uses MobileDevice.h) for installation of apps, we come across this error: AMDeviceValidatePairing failed

How to solve this in MAC?

Answer 1

So if you are using fruitstrap, it actually uses MobileDevice.h for accessing the MobileDevice.framework. MobileDevice.framework is actually contacting iTunes and doing the required process. In between it opens up a process and fails to terminate: /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/Resources/usbmuxd -launchd

On terminating this process, it will solve the problem and AMDeviceValidatePairing will succeed.

Answer 2

I encountered the same error in fruitstrap.

My problem was that iTunes was not authorized to access data from my mobile(since I had just update to 7.1.1).

So I opened iTunes once, gave authorize in the dialog which opened. In the device a popup asked me if I wanted to "Trust this computer". Once I gave yes, I got this error no more.
