Warning! OTA update for Android 5.0 Lollipop will fail on modified devices

Android 5.0 Lollipop has been available as an OTA update for a number of devices for a few days now. Devices like the Nexus 5, Moto X and LG G3 already have access to the OTA update, and many more handsets are in line to receive it. But a change to the way the update process works means that for phones and tablets that have been modified, the OTA update will not work.

The update script used to upgrade from one version of Android to another has been changed. Now, rather than checking and updating individual files, the script looks at a device's system partition as a whole. This, as Android Police points out, means that anyone who has rooted or modified their Android phone or tablet in any way will find that the OTA update will fail.

However, this does not mean that all is lost. While slightly annoying, if you have modified your system partition all you need to do is reflash your device with a stock Android image. With this done you can then reattempt the OTA update and it should be successful.

Another option is to manually upgrade to Lollipop. Factory images for Android 5.0 Lollipop are available for some Nexus devices – we've looked at how you can install the update on a Nexus 5 and how to upgrade a Nexus 7 – and images will be made available for other handsets in the coming weeks and months.

Did you run into problems performing an OTA upgrade?

  • Thanks. Running into problems on my rooted Tab, that this seems to cover. Saved me waiting for the device to charge for a last OTA attempt - I'll just use Kies and drop in a stock img, like the vague error seemed to be pointing me.

    The Lollipop upgrade also fails to perform on stock devices, as is widely reported on the net. I purchased a Galaxy S5 new last week (to replace an iphone 4). It immediately "upgraded" to Lollipop and immediately started to run hot, run down the battery quickly and have endless random restarts. Did a factory reset and the random reboots continued -- 23 in 4 days or so. Purged the cache which helped a little, but the reboots continued and wifi went out too. Fortunately, as it was brand new, I could return it. My sympathies to those of you stuck with a brick. I now have an iphone 6 which works. By the way, I'm not a Samsung hater. I have a Tab 7 and a mid-range Samsung phone for the wife. Both are satisfactory.

    I know I could root the S5, but frankly, getting to that level of detail is not of interest to me. I do respect those of you who do enjoy it, but I have other interests. I just want the damned thing to work smoothly and not require endless attention.


  • I root my nexus 5 manually.... Lollipop is wonderful....

    Google does a dis-service to it's customers, that bought into their os, and are plugging holes. The only time they listen, is when a overwhelmingly majority complain( the sdcard debacle). They say it's an open-sourced os, but like apple, are trying to take too much control over your system, and leave your choices out. One thing I can say about windows(not the phone os, but their pc os) , is that they try to bring all os's up to date, and won't leave you hanging, unlike android, which kills off support, as fast as they can. So many phones are left behind, sometimes within a year. They're making policies, that defeat the reason you went to them in the first place.
