Thanks. They are fine.

Excuse me. I don't understand what you want to express. Do you mean the
situation of the old paser with the new firmware for checking the firmware? For
the normal situation, the old paser would not use the new firmware. And I put
zero in front of the new firmware to prevent the old paser from running it. That
is all I do.

If you don't mean that, I could promise the new firmware I release would contain
the valid string unless someone modifies it.
