Nexus 7 update to Android 4.4

This morning i got a notification on my Nexus 7 (2012, WiFi, nakasi with ClockWork Recovery) that a new System update is available for installation. YEAH Android 4.4 is there!

So i rebooted to install it. My tablet went in recovery mode to install the new image. A few messages appeared on the screen like patching system, copy new files, deleting files, setting symlinks and then it said "installation aborted" the error message was something about the cache (couldn't completely read the error message).

Hmmm.... strange. I just rebooted the tablet and got stuck in a boot loop.

I downloaded the Factory image from Google and the Nexus Root Toolkit. I put my Nexus 7 in to fastboot mode (while in the boot loop press the volume button and the power button for about 10 seconds) and installed the usb drivers on my computer (via Nexus Root Toolkit).

Under "Back to Stock" i choose "Soft-Bricked/Bootloop" and pressed "Flash Stock + Unroot", clicked OK, enabled "Other/Browse...", cklicked OK and selected the Factory image I downloaded earlier.
Entered the MD5 checksum from Googles download page and flashed the Sock image. So... now I have a factory reseted Nexus 7 with Android 4.4. All data is gone.
It will take some time to get my music and E-Books back on the device. As well as all the Apps. But the worst thing is that all my High scores for Fruit Ninja are gone :-(

Now I installed a custom recovery image and root again.

Now, that was a lot of trouble to get Android 4.4.

Update 14.12.2013:
Today I got the update to 4.4.2. This time the update went smoothly.
But I couldn’t update any installed Apps via the Play Store. The updates seem to download normal but the installation process didn’t finish. After a reboot everything is working again. Strange.

Let’s see what will happen next.
