    • Viraj SK

      If you’ve Xperia Ray with model number “ST18i”, you can surely update your phone..

      • Vatzee

        Hey I have tried But It gives error
        It says unknown loader….

        • Viraj SK

          Please don’t apply this update. O2 hasn’t rolled out any official ICS update. And hence it may not work on your phone.

          May be you can try unlocking bootloader..
