regarding unit 6ED1052-1HB00-0BA8:

I have version FW V1.08.01 in the device. 

I have downloaded the file: logo_fw_v1_81_03_up_bm.zip

checked the checksum so the file is not corrupted.

extracted the ZIP file  so the SD card has two files

up_bm.bin

LOGO_U_P.bin

I was expecting that the LOGO should start updating efter power down and power up agian

But it does not updating , it starts as normal.

I assume that the downloaded file has the FM V1.81.30 and my Logo device should start the pudating process.
