I've done it but I had a backup of all the important data first so it wouldn't have been the end of the world if it'd gone wrong.

If I recall it was a case of doing a restore to factory defaults, then following the initial setup process, you'll get warned that the data is going to be overwritten but I found mine was still there and just the actual TOS install was overwritten and set up from scratch. If you don't have a backup though then don't risk it!

An official response is in the last post on page 1 of this thread:

But it does still come with some risk, so a backup would be essential if you ask me.

Mind you we wouldn't have to consider it if they would just release stable software that works is it me or is Terramaster the only company that does this? :roll:

It could not be done as you requested. Only re-installation could roll back to the former version.

Is there a way to just turn the auto-update off? I've had my F4-210 for a few months now and it's now 2/3 on updates that happen in the like middle of the night and i wake up to a beeping unhappy nas.
