where to download satio firmware file?

[satch1234]

Hi, I have a satio that is basically dead. O have tried seus, sony pc companion and every time the update is installing, the phone loses connection with the computer and fails. In seus a message appears that recomends that i charge the battery, even though i charge the battery for hours before trying to update it. The phone is dead. Could the battery be the problem? Or should i try o get the firmware somewhere and try A2 uploader or Set tool 2 or omnius?

Try with another battery,if also failed take the phone to some private repair shop.
