I am using 14.04 and an iPhone 3GS running iOS 6.1.6. All was working fine out of the box until I decided to restore my iPhone to the same version of iOS on a windows machine. After doing that Ubuntu doesn't mount my iPhone and I get an error "Unable to connect".
So far I tried reinstalling
libimobiledevice4 using synaptic package manager and also tried to install
sudo apt-get install libimobiledevice-utils;idevicepair unpair && idevicepair pair && idevicepair validate)
unpair - gives me an error saying that device is not paired, pair and validate are working but the phone does not mount anyway.
Is there any other solution besides reinstalling Ubuntu?
