    Hey i have xperia neo l wnt to update 4.1 without doing root.. When. I can do this.. Which date. Because my phone is very slow… Reply me fast as u can…

    • Anurag Kumar July 9, 2013 at 3:39 pm - Reply

      Yes you can if there is ftf for it made by developers, we need to check that…
      Officially Neo L will not have Android 4.1 as Sony made it clear….And I guess you need to unlock bootloader and root as well before updating to 4.1.2 if it is there.
