How to flash SiyahKernel-XT for the Xperia T LT30p

January 11, 2013

XDA Developer member gokhanmoral, the well-known developer of one of the best custom kernels in town, has released the SiyahKernel for the Sony Xperia T LT30p. Now every Xperia T user and developer can take advantage of this fast and optimized kernel. This kernel comes with autoroot, I/O schedulers, optimized governors, custom ClockworkMod-based recovery with touch gestures, and STweaks support. The kernel also has undervolting and overclocking support with fast-dormancy disabled by default.

Currently, the latest version has a 2- to 3-minute lag when you apply settings. Some STweaks settings are also not very effective. Unfortunately for JellyBean ROM users, the SiyahKernel only supports Ice Cream Sandwich ROMs for now. Don’t worry, though, because the developer is still working on this kernel, so stay tuned for more updates from gokhanmoral.
