New Z5 will not update to 7.1.1 or software repair to update
I have last week purchased a brand new Sony Xperia Z5 Compact (I know, late to the party, but I wanted a small phone) and am having problems with software update. The update downloads but will not install and I am getting repeated messages that an update is due – when I try to install (full battery, stable wi-fi etc.) I am told the update could not be installed.
I have installed Xperia Companion on my pc and tried to update this route. It initially tells me ‘Your Xperia is already running the latest software available’.
I have therefore run the software repair option. This also ends up the error message
'Software repair error. An error occurred while repairing your device'
Error info: UEGetPhoneInfoMissingInfo
I have factory reset the phone and retried all with the same error messages. The difference this time being that when I try and install the update from the phone, the phone is off for only a very short time, less than a minute, before coming back to tell me the update has failed whereas before it was taking a sensible amount of time to at least try and install. I have tried to clear data in the software update app as advised.
Returning to try and update through Companion I am using the Sony supplied cable; ensuring all other programs are closed whilst running the repair; I have tried uninstalling and reinstalling Companion; tried using Companion installed on a different computer but to no avail.
On the second computer the error message is also 'Software repair error' but the error ref is UEStartNoMorePorts

It would be great to know how to fix this, I don;t want to give up on the phone yet as there are a lot of things I like about it but it is very frustrating with a new phone
