After a power failure my HS-453DX-8G is no longer working: I am able to boot into BIOS, but only the UEFI shell is available (having already taken my drives out).
I’ve followed the firmware recovery guide which says the DOM should be /dev/mmcblk0, but this device is not available when I boot or to fdisk.
On one of many reboots QNAP OS showed up as a boot option and it did boot up, but as there were no disks inserted it wouldn’t start. I’ve rebooted another 20+ times, but I’m not getting the DOM boot option again.
It seems the DOM for HS-453DX is soldered on and I’m not sure it can be replaced?
I tried flashing the DOM image to a USB stick and boot from it. It’s slow, but boots to a terminal login screen. Unfortunately the NAS doesn’t to get an IP address from the router, I can’t find it with Qfinder nor check the web gui.
Do you know if the DOM replacable on the HS-453DX? Or have any hints as to how I can get it working off the external USB stick?
I’ve tried booting from a Clonezilla USB stick to rewrite the eMMC DOM, but the eMMC does not show up as a device in BIOS or as /dev/mmcblk0 to Clonezilla/Debian, so there’s nothing to write the dom.img to.
This is why I “replaced” the eMMC with an external USB stick. When the NAS boots from the external USB stick I would expect it to acquire an IP address and show up in Qfinder, but it doesn’t, so I can’t update firmware as described in the firmware recovery guide.
If you’re unable to follow the steps, or if /dev/mmcblk0 remains unavailable, we recommend you open a support ticket. Our Support team will then be able to assist you directly.
