Error when upgrading Android 4.3 to 4.4.2 on Nexus 7 (2013) tablet I have a brand new Google Nexus 7 (2013) LTE tablet and first thing I did, was to check if there is any sys update for my device. It was. System reported that 4.3 --> 4.4.2 update is ready to download and install.

However, after updating and hitting button to install, I got Error message and a droid lying icon. After this my tablet has restarted and reverted back to 4.3.

The strangest part is, that I can't repeat (try to install again), because now my tablet claims, that it is up to date, though it still carries factory 4.3 system version on-board.

Is there any known reason for this behavior (not able to upgrade and then to even re-download update)?

Is there any solution to this problem, except:


waiting for 4.4.3 or
manually updating using images?


I am a rather beginner to the Android system, so terms like sideload or update radio/baseband from .84 to .97 says quite nothing to me! :[

EDIT: I read about this (not being able to OTA-upgrate to 4.4.2), but the strange thing is, that most of these sources talks about 59,1 MB upgrade image, while mine was 253,9 MB (five times bigger).

EDIT: I have cleared Google Services Framework cache and data, as suggested by dotVezz in a comment and then I was able to restart download &amp; upgrade to 4.4.2 process. 
Second attempt ended with success (system upgrated to 4.4.2), so my previous experience seems to be a one-time problem.

If you clear the data for Google Services Framework, you can force the OTA update to start again.

There are a few downsides to this, but with a brand new device, you can safely clear the data and perform the OTA update.



Old Answer...

As deailed in this question, you can download the 4.4.2 image directly from Google and install it on your tablet from your computer.

One method is to use Fastboot:

If you're using Windows, you'll need USB Drivers (official link, and easy mode link, Koush's Universal Driver). The file downloaded includes instructions, which basically boil down to...


Reboot into Bootloader/Fastboot mode.
Connect your device to your PC with USB.
Run the appropriate flash-all file for your Desktop OS (Windows .bat files and Bash .sh files are included with the downloaded Android image). 


Note: This will also erase all data on your device. Make sure you back up whatever you want to. If I remember correctly, there's a flash-base or similar option that will not erase your data, instead of flash-all.
