Uhm, actually I've tried serload all loader_bl I've been able to find. The 
problem is always the same. The upload process work, the loader seems 
installed, but at the next reboot the 2.4 is always there. Look at the log:

I guess if the loader you are talking about are somehow different from the 
loader_bl found on sourceforge (maybe the original siemens loader??) In that 
case, where I can found them?

Here is what happens when I try to serload a CE (4.1) image (but it's always 
the same with any CE images, from 3.0 up to 4.1):

C:\simpad>serload "CE.net 4.1 for simpad__S842-SI-INT-152"
