Install Official LineageOS 15.1 ROM on Sony Xperia T

Sony Xperia T took its covers on September 2018. The device came with Android 4.0.4 Ice Cream Sandwich out of the box. Running on top of Ice Cream Sandwich is Sony’s own Timescape UI, itself a very beautiful and navigable user interface. Aside from a few hiccups here and there, Sony’s UI is solid. But the outdated ROM’s will always find a fence for the new interface and customizations. Presently Android 8.1 Oreo-based LineageOS 15.1 build got ready for this device. Here is a simple guide on how to download and Install Official LineageOS 15.1 ROM on Sony Xperia T.

The Xperia T is a strange mixture of design influences and combines the refined edges of the Xperia S with the unique curved back of the Sony Ericsson Xperia Arc. The 4.6-inch screen uses Sony’s Bravia Engine to create a convincing and bold picture. Sony’s insistence that the dual-core Snapdragon S4 can match the performance of rival quad-core chipsets like Nvidia’s Tegra 3 seems credible. The rear shooter is of 13MP with Autofocus.
