    And, by the way, GREAT work from Sony developers: ICS 4.03 FLYES on the Arc S… super fluid interface.
    let’s see how is the battery life, but so far it works fine (and all the settings have been maintained in the upgrade from 2.3.4 to 4.0.3, so thanks!.

    hey… wait a minute… but after that error flashing, the phone sucessfully starts with the new SONY and XPERIA logos… and the ICS 4.0.3 version (Sony compilation number 4.1.A.0.562) is sucessfully on the phone (after some post-upgrade process to optimize Andraid Apps and contacts Database… uff!.
    So, everything is fine then, Xperia Arc S sucessfully upgraded as stated by the process and information here.

    Followed process step by step.
    Tried on a Xperia Arc S, the update process fails at the end of the flashing process, with these last lines error log:

    23/002/2012 15:02:13 – INFO – Flashing system.sin
    23/004/2012 15:04:34 – INFO – Ending flash session

    23/004/2012 15:04:35 – INFO – Device connected in flash mode
    23/004/2012 15:04:36 – INFO – Device disconnected

    Tried two times, always with the same error.

    Worked perfectly first time. The only thing I had to do which wasn’t in your tutorial was go to the Flashtool drivers folder and install some Windows drivers. Thanks very much.
