How to uninstall last software update??

[Masya]

Since your upgrade to the newest software, I have a lot of problems. It's more "missing options" than problems. The silence option disabling data, no option to open contacts during a calk, only if going to menu and contacts, and in contacts additional window appears, so if I need Favorites, I need to go over the general window. The only 1 good thing in this update it's the camera. All the rest did awful experience of using sony.

Is it Lollipop version and not Sony? And I have Z1, if it's matter.

It seems too risky and very long process. Maybe there is another solution, like fixing those new options to more friendly?

I support this.

Much people have A LOT troubles with Lollipop. Not only bugs-n-lags but interface itself is user unfriendly.

And most of this peoples isn't experienced enough to do mentoned "geek procedures", and/or have no time for study them.

So they just blaming SONY and bying new phone. Throwing away or trying to sell their old Xperia Z*/compacts.

In fact, there is MUCH Xperias on local second-hand goods markets after the last update. If in January most ads was "bying SONY", now it's "selling my xperia". Some trying to sell 3-month old devices for the less than half of the price.

I find it's totally abnormal.

@uliwooly You forgot the backup. And what about warranty that I can loose?

@Masya

flashing "COULD" void the warranty.
