    Hi everyone I have a
    T-Mobile Lumia 521
    I don't have service on it
    I have home Wi-Fi
    Tried updating it to Cyan for three days straight
    It keeps saying it downloaded the update but can't open it
    This is getting annoying
    My brothers Lumia 520 updated fine so did my Lumia 925

    Perhaps you should clean up a bit.. Freeing up some space might help.. Back up your pictures and music to a pc and delete the ones you have on the phone

    Unmount, power down and remove your microSD card. Restart the 521 and apply update.

    You could also try to install new firmware :D but that should be a last resort

    Updates are known to fail with microSD mounted...

    ​You'll get back to it, I'm sure.
