Can you roll back updates?

I've recently had a notification on my Xperia T to say it had a software update available. So I installed it today. It's perhaps a bit more modern but it's terribly annoying. For a start it deleted the android browser with all of my bookmarks, which was pretty annoying, but mostly it's the way the keyboard works. I use the swiping method mainly and it worked everywhere and was very intuitive. The new one is garbage. For a start it doesn't work on Google and YouTube and doesn't offer close matches if you got it slightly wrong. Often it won't get basic words and doesn't offer alternatives. It's horrid.
Can I roll back the update (please say yes).

You can flash older firmware:

Thankyou, I've had a quick look at that. If it's possible I might void the warranty then I'll leave it as it's broken down and has needed repair and it probably will do again. It's just annoying that they don't tell you what's in the update (like deleting the browser), and they mess around with a perfectly good keyboard and if you don't like it then it's tough poo.

Yes,unfortunately you cannot do anything.The browser is Chrome and they have changed the overall background.But is it up to the developers.

Yes I agree, the old keyboard on jellybean. 4.1 was way good than the new one. This keyboard is dumb. Word suggestions are worst and also if I swipe over those suggestions to chose another word on every swipe words Gets putt on my writing box. This is absolutely annoying.

So as far as I can make out. My first problem is the keyboard. When I used to type it would show alternatives in case a word was misspelled. This new one jumps straight to inaccurate predictions for what you type next, so if you've made an error you have to tap your way back to the misspelling. This is crap.
Also you get the full functionality of the keyboard on Facebook and forums and the url bar of the browser. But you don't get it on Google searches. So you start swiping and nothing happens. This is crap.
Could someone explain why you have different functionality of the keyboard on various sites, whereas it used to be one excellent keyboard for everything and also explain how this constitutes progress?
Cheers.
