So it's the original (called v1 here)

If you are looking at the labels, then 4.1.6 would be the firmware it shipped with.  Hopefully you updated that periodically.  The final firmware was 4.1.16.

It's been stuck for 12 hours and the only LED showing is the Disc Activity LED that blinks every 5 seconds. All the other LEDs are not doing anything at all.

Start by powering it down, and removing the disk(s) - labeling them by slot, so you can replace them later on.

The power up the NAS, and see if RAIDar finds it, and reports a "no disks" status.  The NAS uses the following LED codes:

LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by an 1s delay, followed by a number of slow blinks.  The number of slow blinks will be the error code.

Current error codes:
1  - Vendor mismatch
2  - No disks detected
3  - Bad contents on root partition of disks
4  - Flash error
5  - Unsupported RAID configuration

So the NAS should also give you the "no disks detected" pattern when you do this.

While the disks are removed, it would be good to test them.  You need to be able to connect them to a Windows PC to do that (either with SATA or with a USB adapter/dock).  Windows won't be able to mount them, but the vendor diags will find them and can test them.  Use Seatools for Seagate disks, and either Lifeguard or WD's digital dashboard for Western Digital.  Run the full generic (non-destructive) test.
