Can't Upgrade to 5.1

Can't Upgrade to 5.1

Hi,

 

I am an Xperia Z user from the Philippines. Last week I have received an update to Android 5.1 lollipop so I've decided to upgrade my software from Android 5.0.2. I was asked to download the necessary files from my phone to start with the update, the file is about 400mb. After downloading I was asked to install the files so I click the install button. My phone restarted and the installation began, upon updating, my phone suddenly restarted and continued to boot. I tought the update was already finished but when I checked I am still using android 5.0.2 firmware and the software update still appears on my notification. I tried rebooting my phone, installing the update on the PC Companion but none worked. Please help...

Try settings-apps-all,scroll down to software update app and force stop and clear data. Restart.

I just tried force closing the software update app and clearing the data, I also restart my phone and downloaded the update again but I still am getting the same error. Is there any other way to fix this?

Perhaps there is a server error? @Johan what do you think?

Re: Can't Upgrade to 5.1

From what I can see its not a server related issue. So I suggest that you try to run the update via PC Companion just to check if it works or if you receive any specific error there as well.

 

Sorry, I just noticed that you've tried PC Companion as well. Which error did you receive from PCC when you tried to update?

Hi Johan, when using the PC Companion I always get the message that I am already using the latest firmware but when I checked on my phone my firmware version is still 5.0.2.

That sound a bit strange. Please send me your IMEI number over PM and I will forward this for investigation.

See the above. Same error and PCC helped.
