Hi @jln_brtn , unfortunately replacing the DOM and retrying the steps to restore the image didn’t solve it for me.
For good measure, I also tried writing the image to a USB stick and setting the Qnap to boot from the USB stick with the image. I got the exact same errors. This strongly suggests the F_TS-X53U_20141125-1.2.8.img image on the Qnap site is bad.
I ended up installing TrueNAS onto the larger sized DOM. So the DOM seems to be working just fine.
I’d prefer to use the Qnap software, but if it is corrupted, then that’s really not an option.
If @Yvette and @Regulus could share how the support team checked the image please, that would be greatly appreciated! Were they actually able to restore it successfully to a TS-1253U-RP? And could they share the checksum of the F_TS-X53U_20141125-1.2.8.img they were testing with so I can compare it with mine please? Even when I write to a new DOM or to a USB stick and boot from the USB stick, it’s the exact same issue as what has been reported by multiple other users in the Polish Qnap forum (error while loading shared libraries: IibuLinux_Util.so.0).
