The OTA Firmware update is not bigger then 200mb and comes only 1x at Month, i think this should not be so big problem? If i can ask you, where do you come from and what kind of connection do you have?

And you hide the firmware.
it is suspicious
I'm from Ukraine
if the firmware will not be
in Ukraine, I will write in the press that you are a firm of liars and you cannot believe
