Doing so i found a typo hereby :

Code:
PLUG1H        Map YUPS ROM image to page 9 (port 1 high page)
H is wrong, U is right => XEQ PLUG1U

And on the DOS line :

Code:
java -jar clupdate-1.1.0.jar --update rom_files_220629.zip COMx 4800
=> Do not forget to replace the x into COMx by your COM number (mine was COM2 on the GPD Pocket 2 and of course got an error with a x instead ....).

Worked well besides a transmission error during the update phase that i had to restart over on the 41CL and it resumed from there.
Maybe one ROM has been missed in the process ?

I redid a
Code:
Code:
Command       Description
------------  ---------------------------------------------------
CPONLY        Enable compare mode.
"*"           All Flash memory will be scanned
FLCHK?        Scan Flash ranged specified in ALPHA

And got no update proposed, so i guess all went well :-)
(first time i tried without the XEQ CPONLY and it was running crazy slow as Monte is warning above)....

CPONLY mode is fine if the Flash is known-good. That is, nothing messed with the Flash since the last update AND the last update finished cleanly. CPONLY only compares FLDB values between the 41CL and the PC, so it's only good if the YCRC values in the FLDB actually reflect the state of the Flash. An update that doesn't finish cleanly means that some pages may not have been updated, even though the FLDB _has_ been updated. So, I would probably run FLCHK again, but NOT in CPONLY mode. Or look at the PC screen to see where things went wrong.
