Fix for: (error code 110)Mount of Outer DMG Failed?

[Alvin777]

Hi Macrumors friends.

Whenever I get to create a Yosemite installer, at the last stage,
createmediainstall fails to make the flash drive bootable- any fix for this? This is what it looks like in Terminal:

/Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction


Erasing Disk: 0%... 10%... 20%... 30%...100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Couldn't mount dmg /Volumes/Install OS X Yosemite/Install OS X Yosemite.app/Contents/SharedSupport/InstallESD.dmg (error code 110)Mount of outer dmg failed.
Done.

Thank you in advance.
God bless, Revelation 21:4
