Won't install update

[Cpcollins65]

Has anyone had a problem installing the current Android update.
My phone gets halfway then reboots and says unable to install update.
Any suggestions?

@SVMO

This could be the solution for you. I suggest you to try and let know after if it resolves your issue.

If it works, consider to accept it as solution for this thread.

I'm currently getting the same problem on my XZ. The current build for me is 39.2.A.0.374. It says there is an update, it downloads, phone restarts & then it says can't install.

Well after trying a number of times it has finally installed.

Is anyone else having issues with their xz updating today?
I've tried numerous times and it seems that it just doesn't want to install.
It downloads fine, asks to install, it restarts, then loads up and then finally says could not install.
Any ideas why this is happening and how to fix the issue?
Many thanks

I now have an annoying icon top left corner as well saying could not install update

Hi 

I Started this original thread and my phone still has not updated. Sony have had details but I have had no response. 

I am really dissapointed as my phone works great but I am now begining to worry a bit about security.

I know that people are recommending doing Factory resets an system repairs but I have had this phone from NEW and I should not have to mess about to get it working correctly.

Can someone from SONY at least acknowledge that there is an issue and they are sorting it!!

Try whipe data and cach update aplication,restart your phone and then let it search update and install tru wifi. Then let it restart and dont puch any buttons wile it reboots between instalation. If it fail just try to restart again before second update attemp. Im from belgium and use got the RU rom (i flashed 6.0 mm in december myself) it updated the second time itself. it got less bloatware and faster updates to me.good luck

Hi @KeithB

I suggest you to read and follow this thread. It takes about 2 hours, but it is perfect in case of errors and system perfectly installed with perfect performances.

Hi everyone,

First of all, I'm very sorry about the late reply and for the inconvenience this has caused. I have now received new information about this.

You might experience the following when trying to update your device to Android™ 7.0 (Nougat):

• If you try to update OTA, your device may restart after downloading the update. After the restart, you may get an error message saying that the update could not be installed. 
• If you try to update the device using Xperia™ Companion, you may receive the error message kResultCode_DeltaUpdateResultDidReturnFail. 

This is due to the fact that Google™ checks the OTA software availability on the Google™ server (not the SOMC FOTA server) during shutdown. Since no new software can be detected (because Xperia™ is using the SOMC FOTA server) the GMS deletes the update command. We have asked Google™ to register our product on the Google™ server to avoid this.

A software update has been released to fix this.

Note! Software rollouts are a phased process - timings & availability may vary by market/carrier.
