According to Sony, the update build can be flashed using company’s recently released Flash tool, but it would need the bootloader to be unlocked first.
Several key features like Voice-calling, Wi-Fi, Bluetooth, NFC, Google Apps are currently missing from this update build due to various reasons. Company however notes that the final Jelly Bean update for Xperia T is not very far.
“We’re now making an early alpha ROM of Jelly Bean (Android 4.1) available for Xperia™ T, along with the open source archive, as a way for us to get valuable feedback from the custom ROM community (although we are not far away from the official release of JB for Xperia™ T). Thanks to the great dialogue we have with open community developers, we see this as a great way for us to get input, and for the open developer community to get to try this alpha out hands-on,” company noted on the developer blog.
