Regardless - is it "month" or "week"?

It'd obviously be "week" for the batch manufacturing identifier, since yours is "17".
It's "month" in the real serial number as they only go up to 12.

For model 221 and other models from the same period, their equipment SN codes typically follow this format: 'A2Y201200148'.

Unfortunately the nas I was discussing was not new when I got it and the numbers quoted were the only ones I could ever find. Sorry if I misled anyone.

Heads up - I had one with a bios code MAPL0304v17 - in other words should work. The internal USB drive in mine was only 120mb. The image file is 126mb and it will happily try to write it, but then you are pooched till you either re-write back version 5. Upgrading to a 16gb thumb drive for $12 (SanDisk 16GB Ultra Fit USB 3.1 Flash Drive - SDCZ430-016G-G46) worked well and ver 6 is now running.

I see here a lot of serial discussion and nothing related to the topic at hand. Really no support here for so long. No one was not able to give a straight answer to the topic maker? This unit is similar to mine, same generation and i was hoping that by now someone answered for this upgrade .... but i was wrong.

Please refer to the TM support reply on the previous page. If your device model and BIOS version are listed there, then upgrading to system 6.0 is not supported.
