When I read out the firmware version on EC21JFA-512-STD, I usually get the response EC21JFAR06A05M4G_01.009.01.009, but this time
the response was EC21JFAR06A02M4G.
What is the firmware version of EC21JFAR06A02M4G?
Also, is it okay to overwrite it with firmware 005 or 009?
If possible, could you please send me the EC21JFAR06A02M4G firmware?
