Restore pre-loaded diagnostic application for Sony Tablet Z2.

[msisim1]

Greetings to all! Somebody can help me?

I have casually removed pre-loaded diagnostic app for Xperia tablet Z2.

How I can restore this application?

I received last firmware update (23.0.1.A.0.167) for Xperia tablet Z2, but nothing happened.

App from market is not the same that was pre-loaded. In the market “Xperia Diagnostics”– v.1.02.47,

but pre-loaded was v.2.

Thank you.

you have two options, 1. use the xperia diagnostics app from the playstore or 2. factory reset the tablet with PC Companion

Are you certain that you removed the preloaded app? have you rooted your device?

If I use factory reset, I will lost all updates.

Unfortunately so. I have removed it by the app named "ProcessManager".

I have not rooted my device.

PC Companion does not keep system apps.

You will have to re-download all apps and updates

Thanks for advice, but I think this app "Diagnostics" is useful, but basically it is possible and to manage without it.

Too many time to reload all apps.

I think what probably to use apps "Diagnostics" and "Elixir2" from a market.

Sony promises updating Android 5.0 Lollipop for tablet. It is possible to wait.

I mean that with last firmware update we have app "Tools" with

Sony's "Back up & restore". May be something else will be.

We'll have to wait and see regarding lollipop
