Upgrade Sony Xperia T to official Android 4.1.2 Jelly Bean update 9.1.A.0.489 Xperia T Jelly Bean

My review so far: you can really feel the butter experience, the phone just responds better than with 4.0.4.
Camera app got a huge update too, hdr photo and superior auto.
new launcher looks good too and is alot handier then changing widgets and or themes. Also boot screen is same as Xperia z. Lots of new audio options too.

So just check it out and fire up that Sony PC companion and don’t let your Sony Xperia T left behind to the latest Android 4.1.2 Jelly Bean tweaks.

Here’s the FTF files whcih you can manually install using flashtool.
