Error unpacking the firmware

[angelbanderasudg]

Hi I successfully extracted the firmware of the device but when running the unpack script I don't get the partitions extracted, inspecting I see that diskname is empty when running, I inspect my firmware with hex dump and didn't get an Efi part, here I suppose that is problem of the firmware maybe?, I try with the example firmware and did not get any problem, I extracted my firmware with flash room in Mac and with ch341a programmer app in windows and the problem persists, any advice?
