Xperia Z Ultra Not Updating to Lollipop

corvustheraven — Tue, 28 Apr 2015 14:06:38 GMT

Yesterday I downloaded the update OTA to my phone, and when I tried to install it, the phone just restarted, and said that it could not update the software. I attempted to try different methods of updating, but none of them have worked.

- Install OTA, battery level 100% and plugged in.

- Tried 3x more

- Attempted to install via computer (Mac OS X Snow Leopard, Sony Bridge for Mac), but it would not recognize my device, and the newest version of the software will not work with my computer.

- Called Sony support, and they were unable to help either, and stated the conditions I was trying to do the update from were 'unstable'.

Here is a screenshot I get of the error after unlocking my phone from reboot: http://postimg.org/image/pxgv1o07t/

Is there any way to apply this update? The failed update notification is stuck in my notifications bar now, and it is quite annoying...

it'll be wise to redownload Bridge > restart your computer > try again

if you try OTA, do you have at least 1.3GB free (internal storage) on your phone?

I have tried reinstalling and restarting the computer, and neither has worked. I even tried using a different computer, and it didn't download the update...

I have 12GB free on the phone, and another 7GB on an external card free, so that's definitely not the issue.

I have tried on both my Mac and my PC (Windows 7) at work, and neither have worked. On the Windows 7 machine, it recognizes the device, but says it has failed to connect to the server to check for updates.

I've seen issues like that before, it could be a temporary server issue.
