I use google translator, sorry for the mistakes
I can not update your phone because it does not work download mode mode. Perform all the steps correctly. I installed the drivers. One LED lights up in green. The computer sees the phone. After a while, xperia turns on and starts charging. Is anyone able to help me?
Try using Sony Update Service

Instead of plugging it into the phone once plugged into the PC, try plugging it into the phone first, THEN the other end into the PC (doing the steps in reverse).
This is the way I managed to do it.
