15:22:02 Sending 2560 2816 2560 256 = 8192 bytes sent
15:22:26 Serial COM25 closed.

For the following section, I assumed that you have mapped and activated the UPDAT-3A.ROM image in your 41CL.

In case you have not done it previously, I would suggest you to do a complete update of your 41CL with the OS protection activated before doing the OS sector.

I was thinking to save time scanning just the page interested to the update, in this case
"000>00F"
so that:

On the computer:
java -jar clupdate-1.0.0.jar --update rom_files_171021.zip COM25 4800 RETURN]
Code:
HH: MM: SS --update [fileName: rom_files_171021.zip] [portName: COM25] [baudRate: 4800]
I should see
HH: MM: SS File rom_files_171021.zip loading ... done
HH: MM: SS Serial COM25 opened at 4800 baud.
HH: MM: SS Waiting for 41CL commands ...
On the calculator:
CMOPEN
I should see on the computer
Code:
HH: MM: SS Received OPEN_CHANNEL_REQUEST(0x41)
HH: MM: SS Sent OPEN_CHANNEL_RESPONSE(0x42)
On the calculator:
OSUPDT
"000>00F"
FLCHK?
-> I should see the Outdated ROM images report on the computer at the end of the check
"000>00F"
FLUPD
-> I should see update activity on the calculator and on the computer
CDBEXP
-> I should see, now, 0 outdated on the Outdated ROM images report on the computer
CMCLOSE

is this procedure correct?

Yes that is correct, but I would add the OSPROT command just after the FLUPD command and limit the scan/update range to "000>007".
