Update Galaxy S2 SGH-T989 to XperiaZwiz UVDMD5 Jelly Bean 4.1.2 Custom ROM

We are proud to present XperiaZwiz UVDMD5 Android 4.1.2 Jelly Bean custom ROM for Galaxy S2 SGH-T989 from T-Mobile.

But what’s so great about this tool that we decided to choose for this guide? After you flash it on your smartphone, you will notice new changes in how your device operates. These changes are all very welcome, since they mean the following: your handset will put on a better performance, new features will get to modify the looks and feel of your device, in terms of battery life you will see only improvement and so on.

What we particularly liked were the Xperia Keyboard, Xperia Launcher, Xperia Widgets and many more. What we didn’t find attached to this ROM were the WALKMAN app (plus the sound enhancements it comes with) and Bravia Engine. Stability is something that also comes with the package, so no worries there.

  • root the Galaxy S2 T989;
