NAS520 keeps rebooting

MinoS · March 2019

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.

So usb restore didn't worked. Seems like it start to restore and then reboots as usually.

I have the exact same problem with my nas 520 now. It started yesterday. Can you tell me what you did to fix this issue? Assuming that you got your NAS fixed?

@DjDunkel Hi there ! Sorry for the late answer. Had no time to fix the nas yet.
I've bought the serial cable and now I see in console that nand flash is corrupted. So it needs to be recovered from console. It won't flash from sd or usb.
