Hi. On page 1 of this thread you mention "Download TNAS PC 5.2.506"
TNAS PC itself announces that there is a 5.2.210 available.
Can I download/install this one?

F2-221 en F5-221 successfully upgraded to 7.0.0403.
Took quite long, but finally there were no issues at all, even the volumes on USB survived.
Thanks!

5.2.506 is the later version, so download that from page 1 of this thread (Earlier versions may not be TOS7 compatible.) This is a Beta, so user beware etc, etc. If you have more than one pc keep one at the earlier level suggested by the app (for TOS6 and previous) and put 5.2.506 on another pc for TOS7 to be safe(er).

I have an F8 SSD Plus model. After updating to TOS 7, the device does not work at all and freezes. I can't even test it. The system is beautiful, but it's still very raw.

In addition, please do not distribute this update package to users who did not participate in the TOS7 Beta test, to prevent it from being used on incompatible versions.

Thank you.

I'm sorry, you misunderstood me. I have no problems booting the TOS7 system. The system turned out to be extremely unstable. Freezes during operation. I wanted to reinstall and install TOS6. But I did not find an article on how to do this correctly. I wanted to clarify if you have instructions. There is no data on the system, I can install everything from the beginning.
Thank you.
