Hi all,
I managed to get the 4.4.3 Update finally!
*Note, this also works with Nexus 7 devices.
For those who cannot wait do the following:
Goto Settings > Apps > All
Scroll to Google Services Framework (GSF)
Select GSF and then disable it and reboot your Nexus device.
Once rebooted goto Settings > Apps > Disabled
Scroll again to GSF and clear the cache.
Re-enable GSF and the device should tell you a system update is available in the notifications.
Download, install and enjoy.
Cheers
Rob.
Worked for me, thanks mate!
