Problem For Some? Google LG Nexus 4 OTA upgrade to Android 4.4.3 getting stuck in “Installing System Update…” Loop

CAUTION: if you haven’t yet upgraded your LG Nexus 4 Android phone, you may want to wait to see whether this is a more general problem or not. I was excited to try the OTA upgrade, but it got stuck in the “Installing System Update…” loop. After 30 minutes of infinite loop, I pressed the Power Button until it rebooted. After that, the Update to 4.4.3 completed successfully. Details below…

This is a Google Play purchased phone, running 4.4.2 without any hacks or modifications, unlocked but unrooted, on the T-Mobile network. The update happened on battery, no USB connection.

UPDATE: I’m not the only one with this issue. At least two more people posted this problem in the Android Central LG Nexus 4 forum

Here’s what I did so far… You decide if you want to take the risk or take a more prudent wait and see approach.

The OTA Update is Here
This morning the Over the Air upgrade alert came in for the Google LG Nexus 4. The alert said, Android 4.4.3 is ready for you to download and install! So it is goodbye Android 4.4.2 and hello 4.4.3!


So the first thing you do is touch to download. You don’t have to be connected to the AC power or an external battery, but it is a good idea to make sure that you have plenty of battery power left. Since this is only a smaller version upgrade, an AC or external battery is not a must. It is a good idea however to be connected to a fast Wifi network, unless you have fast, free and unlimited data. And to be on the safe side, connect to a trusted Wifi network (eg Home or Office).

As you can see below, this is a fairly modest size, under 80MB…


After you download, you will see the same message as above, but at the bottom right corner of the screen, the “Download” option will be replaced with the “Restart & Install” button.


I did not reboot the phone on my own before starting the OTA download process. I don’t know if that may have prevented the infinite loop issue.

The MAIN EVENT: The Infinite Loop
Then the Installation begins. The customary green Android getting its “belly” fixed with blue rotating magic will display with a light blue progress bar at the bottom showing progress. However, after 30 minutes, this appears to be stuck in a loop. After each cycle is completed, the screen will flash and then the whole cycle repeats again. Patience is a virtue but a 80MB update does not take that to complete!

Workaround: Patience is not always a virtue
After 30 minutes, I lost patience, so I did the press-and-hold the Power button for a few seconds. The Google reboot screen showed up, and it continued with the “Installing System Update” loop but only for one cycle! After it completed the one cycle, it automatically rebooted the device with the four circle animation (red, blue, yellow, green).

After about half a minute, happy times! The customary message “Android is Upgrading” appeared with the “Optimizing App X out of Y” progressing. And now the device is up and running again. I am playing with it and so far I don’t see any problems or issues with it! I will post updates if I notice any problems. But I can’t test every single thing I do with the device, so it is possible that if there are any issues, they may get unnoticed.

Regardless, Android 4.4.3 is here! Infinite loop and all! Here’s the About page screenshot cropped…
