Xperia SL: Unofficial Update of Software

[MyXperiaSL]

Hi, I have Xperia SL (LT26ii), which i am using it from last 1.5 years. Now as per sony's policy there will not be any updates after 4.1.2 & Build No. 6.2.B.1.96. Just wanted to check, is it possible to update the phone via unofficial update of software version say KK 4.4 etc.? Is my phone needs to be rooted to update the phone for unofficial update?

You have to unlock bootloader to be able to flash custom ROM.

Take a look here and you will find lots of useful custom roms and somewhere details on how to install said roms,

It may take some time to read through them but as I don't own said phone then this is the best we can offer in terms of help
