    Then have you tried Windows Phone Recovery Tool?

    I can certainly say that if you are willing to flash a ROM then it would definitely work, not sure if you are comfortable with that approach though

    Windows phone recovery tool is a separate program. And it can be used to restore/flash original firmware.

    Since you're willing to flash, let me start by asking, what carrier is your phone?

    In that case you can flash the Mexico LTA ROM, it's unbranded and has Denim (no firmware only OS)

    There is a sticky with video instructions in the 920 forums which covers how to dead flash a 920, you can replicate it for your 520. You model variant is RM-915 so search for Lumia 520 Product Code and look for the RM-915 variant.

    Edit: You can flash this firmware product code:
    059S2X9 RM-915 VAR BR CV

    You'll have more insight after watching the video. The process is safe if done carefully. And I've personally used the above firmware on 2 of my 520s and they were stable and completely unbranded.

    Good luck!
