    What's your OS version? Did you do anything special (eg installing an update) before you switched your phone off?

    Also have you tried to do a soft reset (vol up + power)?

    Dunno if soft reset works on Lumia 520 (removable battery) perhaps a battery pull...
    If not, hard reset ... Bing or Google it, it can be accomplished with a key combo (on a dead screen)
    FINALLY, you may have to restore using NSU !
