Welcome to Vodafone Community
I have been receiving a notification,stating " Couldn't install system update " Tap to learn more.The next screen states " Couldn't update. Verification problem. Good news ! There is an important software update available.Please install for enhanced security. Update size : 90.51 MB Try again. Once the download has completed,the above message appears again along with the Restart now message.Upon hitting Restart now,the install gets to 25:% then a error! message appears. The same messages and outcome keeps repeating.
Any help in resolving this problem,would very much be appreciated.
Solved! Go to best answer.
I've just tried to update again ... and it worked. Same on my wife's phone. It was a bit slow and took ten minutes to do but all good. I know Admins have been working behind the scenes and it seems they've done the trick. Thanks to all concerned.
The first thing to do is to see how much memory you have left on the device, it looks like a hefty download and with the space it needs to store the temporary files that come with the update is insufficient for the download to complete. It would be worth seeing if there is anything you can remove. Presumably, you are also downloading over a WiFi connection.
If there are still issues it may be a case of factory resetting and then trying to instal the update.
Thank you for your reply back AnnS. Yes I am using my WiFi connection at home.Device storage=Have used 12.67GB out of a total of 16.00GB. SD Card=Have used 11.90 GB out of a total of 63.85 ( 64GB )
That sounds like enough, but I'd still try to create more. Clear the app caches by going into Settings|Storage and hitting Clear Cache. If it still doesn't work, see if there are any apps you can uninstall temporarily.
Thank you Beth for the tip.The guide takes me to the same screen as per the notification received.It is still the same result.
Try clearing more space as I suggested. Just over 3gb internal ought to be enough, though. I don't think the update process uses the SD card.
Have same phone model and having exactly the same issue. It's exactly the same on my wife's phone as well. Have tried all the suggestions to date but no luck.
Same problem here. Tried calling Vodafone and they said go to a shop. Went to a shop and they said back the phone up and do a factory reset. Not keen on deleting everything!
If you've tried everything else, a factory reset is the next step. I agree that it's also a bit of a last resort, but Google's retore options are a lot better than they used to be.
The first thing it to make sure that all your online data (emails, calendar etc) are synchronised. Then back up any content (photos, music etc). An SD card is the easiest way to do this if you're not using one already. Remove the card before you reset as the process sometimes formats them.
Check that the deevice itself is fully backed up. Backups are viewable in Google Drive and you can see the date. Recent versions of Android have a Backup Now option in Backup & Restore in the main settings menu.
When you sign in again, choose Restore from the same device and all your apps and quite a lot of your settings will come back automatically. You'll probably lose data from 3rd party apps, though you can see which ones back up to Google within the backup itself and some may also have their own export or online backup options.
You'll still have to set up your homescreens again and screenshots before you start can help here (remember to back those up too!). It's also worth checking that any apps (eg news) you told not to use mobile data still don't and that Google Play doesn't update over mobile data unless you're happy with that.
It strikes me that if a number of phones have the exact same issue, then it's not so much the phone at fault but a system error in the download itself?
I'm not keen on going through a full reset only to have the same issue.
Can Admins raise with Vodafone to raise with Android, otherwise this model of phone will always be out of step with the latest updates.
I totally agree with the comments made by GazHo. I also am not prepared to make any adjustments to my phone.Hopefully someone in authority on this forum,can relay the problems to Vodafone about this update.
