title: Cannot mount Developer Disk Image for iOS 13.6 using libimobiledevice
body: <p>I'm trying to use the functionality of libimobiledevice on my iPad to do stuff like change location (<code>idevicesetlocation</code>) and etc. I have no problems if I install the Developer Disk Image using XCode, but as a primarily PC user, I would like to be able to use my program solely from my own computer. After trying the command <code>ideviceimagemounter IMAGE_FILE IMAGE_SIGNATURE_FILE</code> and using the files from <a href="https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases" rel="nofollow noreferrer">https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases</a> for the two files, I get these messages:</p>
  <pre><code>Mounting...
  Error: mount_image returned -3
  </code></pre>
  <p>I've tried this with multiple different file sources and two different iOS devices with the same result. Any help would be appreciated, and let me know if I can clarify my question in any way, I've never really posted on here before. Thanks!</p>
