My phone- sony xperia t2 ultra dual- recently got the lollipop update notice. But it says the lollipop is 1.2gb sized, and it needs a computer, saying that a program must be run on the computer for the phone to get updated. I met a guy who says he would do the update at the rate of N4,500.

Since I don't have such an amount right now, could anybody help me on how I can do this myself, please? Thanks all.

Somebody help!
