Update Sony Xperia U ST25i to Official ICS 4.0.4 Firmware [6.1.1.B.1.54]

Back in 2012, Sony launched new series of Xperias. Few of them were high end devices (Xperia S, Xperia ion), some were middle range phones (Xperia Sola, Xperia U, Xperia P) & rest was low end devices (Xperia Tipo, Xperia Go). All these devices were launched with Gingerbread 2.3.7 on board (Xperia Tipo is exceptional). After a month or two, Sony rolled out ICS update for its flagship devices & subsequently for middle range devices. As we all know that theyve taken a bit long time to release ICS updates, it may not be tolerable. But anyways, finally its out.

Sony started upgrading Xperia U ST25i to ICS in September12. At first, they rolled out 6.1.1.B.1.10 firmware for all the devices. Now by fixing the bugs & issues like random lag & resource management, theyve pushed another ICS update with 6.1.1.B.1.54 firmware for India region. But with Flashtool (firmware flashing tool for all Xperias), you can apply it to any unbranded / unlocked Xperia U worldwide.

Android 4.0.4 ICS update has improved performance & stability over Gingerbread. Along with that many interesting features like face unlock are also added. ICS was one of the revolutionary update from Google & Sony has taken it to the higher level.

In this article we are going to discuss how you can upgrade your Sony Xperia U ST25i to 6.1.1.B.1.54 ICS 4.0.4 firmware.
