The Sony Xperia T is slated to receive the Android 4.1 Jelly Bean update sometime in the first quarter of this year. For the impatient and advanced developers, Sony has released an alpha Jelly Bean custom ROM for the Xperia T. Sony had earlier released an alpha Ice Cream Sandwich ROM for its 2011 line-up of Xperia devices.
The Japanese company is also releasing the open source archive along with the Jelly Bean ROM for the Xperia T. Since this ROM is in alpha, it only has limited functionality, and is squarely aimed at advanced developers to taste some of the new Jelly Bean features on the Xperia T.
The custom ROM from Sony does not include the new Jelly Bean UI look and feel, along with all the usual Google apps including Play Store. Wi-Fi, FM Radio, NFC, Bluetooth and even the modem is also turned off. This means that there is no way for users to make any phone calls via their T after they flash this custom ROM on their handset.
To flash the custom ROM, you are required to unlock the bootloader of Xperia T and then use Sony’s official flash tool. Head over to Sony’s developer website for the announcement, steps and the download links.
If you are tired of waiting for the Jelly Bean update for the Xperia T, fret not. Sony says that the update is coming really soon, and there is no need for normal users to unlock their handset and install this Jelly Bean custom ROM.
