By using the clupdate program of course
Extract from the clupdate-1.0.0-readme.txt included in the clupdate-1.0.0.zip file.
Code:

H) loading UPDAT-2B.ROM ROM image into the 41CL /////////////////////////////////////////////////////////////////////////////////////////////////////
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
This section will show you how to load the UPDAT-1G.ROM image into the 41CL
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
1) you must find which communication port your 41CL serial cable is connected to
2) once found, replace the SERIAL_PORT tag by its appropriate value.
Windows: find your serial port name with DeviceManager and use that name instead of the SERIAL_PORT tag. (ex.: COM4)
Linux..: find your serial port name in /dev folder and use that name instead of the SERIAL_PORT tag. (ex.: /dev/ttyUSB0)
macOS..: find your serial port name in /dev folder and use that name instead of the SERIAL_PORT tag. (ex.: /dev/tty.usbserial)
3) start a shell (aka command line)
4) go to the working folder
5) load the update ROM image into the 41CL
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Type_on_CL: MMUDIS // disable 41CL memory management unit
Type_on_CL: MMUCLR // clear 41CL memory management unit configuration
Type_on_CL: "YFNX" // enter in ALPHA the 41CL Extreme Functions rom image ID
Type_on_CL: PLUG1L // plug it to the lower address of port 1 (page 8)
Type_on_CL: MMUEN // enable 41CL memory management unit
Type_on_CL: SERINI // initialize the serial port
Type_on_CL: BAUD then 48 // set communication speed to 4800 bauds
Type_on_CL: ON // (optional) deactivate calculator sleep mode
Type_on_CL: CF 26 // (optional) deactivate calculator sound

Assuming YFNX is mapped and activated, the minimum do to is ...
Code:
calculator: SERINI
calculator: BAUD then 48
calculator: "820000-0FFF" // physical destination address and length in RAM where the ROM image will be loaded, you can choose another address if you want
calculator: [XEQ][ALPHA]YIMP // not pressing the last [ALPHA] will leave the 41CL in wait state
computer..: java -jar clupdate-1.0.0.jar --upload YOUR_ROM_FILENAME /dev/tty.usbserial 4800 [RETURN]
// wait until you see -> HH:MM:SS Sleeping 5 seconds before starting file transfer
calculator: [ALPHA] // this activate the YIMP function, you should see "RECEIVING" on the LCD
calculator: "820" // physical address to CRC
calculator: YCRC // calculating the CRC of the module, you should see the same CRC displayed on the computer of the file transfered
calculator: "-820 9" // physical address and port to activate
calculator: PPLUG // activating the module
