How do I update NAS F2-221?
Re: How do I update NAS F2-221?
Hi! Based on the model information you provided, for the 221 model, it is necessary to consider the device's SN code, hard disk partition format, and built-in USB capacity to determine whether the NAS can use TOS6.
Please generate and download the log report in TOS > Technical Support > Problem Report, and send it to the technical support email address. We will help you make a judgment.

Seems to me, someone @TM needs to generate a guide sheet(s) to get all the "required" info in one place and, maybe, post it on the support site for the respective models.
{Often, info on this forum gets 'lost' due to users posting (often) unnecessary questions/info on the topic and/or just the volume of information. Then there are the trolls that post far too frequently advertising their own brands of stupidity {/rant_off}}
