After reading all of the notes regarding the installation of TOS7, I performed the update. After 10 minutes of waiting and the NAS not being found on my network, I tried the "Method B" reinstall from the forum notes for reinstallation. The NAS is still not visible on my network.

What can I do the get it back??

The installation of the new TOS 7 Beta requires manually uploading the corresponding new Bootloader file on the initialization page. When you initially obtained the TOS 7 installer via email, did you also receive the corresponding new Bootloader? We have sent the new Bootloader to you via forum private message. Please try again.
In addition, please confirm again whether you are using the TOS6-specific USB initboot boot system.（Legacy for F5-221）

I used the files you provided but it didn't change the outcome, still won't boot.

Thank you but I have solved the problem. I removed the internal USB drive and the NAS booted up TOS7 without issue.
