Hi

The easiest solution is to connect your phone to Xperia Companion (you can download it) and choose software update.

When that does not run like it should then choose Software repair.

When your device is not recognised then tick "mY device cannot be detected or is a Smartwatch'

Hope this helps you.

Let us know how it went please.
