I would suggest that you look at the examples (p.43 to p51) of the 41CL Update Functions Manual.
Example #2 (p.44) show how to shorten the outdated ROMs scan time from minutes/hours to seconds/minutes. (CPONLY before FLCHK?)
Example #3 (p.45) show how to update the OS sector. (OSUPDT & OSPROT)
However the actual Flash update will takes minutes/hours to do.
As suggested by Meindert, it is a good idea to deactivate the sleep mode on your computer and on your 41CL (ON).

Edit: FLCHK? only scan for outdated ROMs, it is FLUPD who do the actual update.

Code:

FLCHK? → Check Flash Memory Against Flash Database
FLUPD  → Update Flash Memory

The update process is clearly explained in the 41CL Update Functions Manual.

Hi Sylvain,
I have read the mentioned examples in the update manual. From my point of view these are very good for people who are more specialists as me. But the steps I have to do on the pc are not mentioned in the examples.
I use your presentation from HHC2017 together with the document "clupdate-1.1.0-readme.txt" that comes with the clupdate software. With these documents I can see, what I have to do on the HP41CL and on the pc.

Yes, now I understand that FLCHK? makes only a scan. My HP41CL is still as before.


Greetings
