Usage

In order to be able to automatically mount your iOS device (such as an iPhone) when connecting it, you need to install libimobiledevice and to activate the usbmuxd service.

Add the following to your configuration.nix:

services.usbmuxd.enable = true;
environment.systemPackages = with pkgs; [
  libimobiledevice
  ifuse # optional, to mount using 'ifuse'
];

You can then mount your device using ifuse:

$ mkdir /tmp/iphone
$ ifuse /tmp/iphone

If you get an error about ERROR: No device found!, check the status of usbmuxd:

$ sudo systemctl status usbmuxd.service

If you see an error

ERROR: Could not connect to lockdownd on device [...], lockdown error -8

you may need to restart the usbmuxd service as reported here:

$ sudo systemctl restart usbmuxd.service

(it may take a bit of time)

Maintainence

Factory reset

The following section describes how to perform a hard/factory reset and reinstalling the latest firmware. First install and enable the required daemon and package.

services.usbmuxd.enable = true;
environment.systemPackages = with pkgs; [
  idevicerestore
];

Shutdown your iDevice and put it into DFU/recovery mode. How to achieve this depends on your iDevice model. See DFU Mode on the iPhone Wiki for more details.

Once your iDevice is in recovery mode, run following command to reset your device. You will get asked which firmware to install and a final confirmation that everything will be erased.

Warning: The following command will reset your iPhone. All user data will be lost. Be sure to backup everything before proceeding.
