Hi,
i have several of these, over the years with different firmware versions and different odd behaviors. Extept one (EC25EFAR06A11M4G) Wich seems to be able to connect with IPv6 and doesnt run into Boot Loops with some SIM Cards as the others do.
is it possible to retrieve a new firmware version for these from you?
