Hi everyone !

I've just bought used NAS520 and it seems to work fine previously. But I just can't get it work.
It just boots.. blinks different leds, start the hdd and then reboots.

I tried different HDD combinations (1 HDD, 2 HDD, no HDD), tried hdd freshly formatted to ext4 - no luck.
Tried to remove the battery - all the same.

Factory reset doesn't help...

Maybe I should flash the firmware from USB ? But I can't find a good manual for that.

Please advice.

    reboot while you create volume?
    The disk was created file system previously?

    I can't even get it working. So no Gui, no access through lan, no volume creation) Just reboot every15-20sec 

    And yes, I tried with ntfs and with empty ext4.
