    Backup your personal data and try a factory reset:
    Settings/backup&reset - factory data reset

    Then try to update again.

    you can try one thing, if you remeber which version was installed on your Z500:

    http://us.acer.com/ac/en/US/content/drivers/5579;-;Z500

     

    select KitKat on operating system, then select OS tab, download the correct image, copy to your microSD, boot to recovery and choose to install update from SD, then select your file.

     

    if it gives you error, you downloaded the wrong version.

     

    Honestly, if you are unsure about your version, give Acer support a call.

    Hi, I have the same problem on my new Z530, I can't update from 5.1 but I'm getting the 'new update' notification all the time.

    It downloads, and reboots to attempt installation, but then it fails with 'unexpected contents' error detailed above. Can you help me get the update to work?

     

    p.s. i've done factory reset several times to no effect.
