This is exactly what I did:

but nothing happened
I have no problem in turnig on (fixed ) each amber led and the turn it off.
I have no problem in turnig on (fixed ) status and HD amber or green led and the turn them off.

Meanwhile, I saw brightness is a "strange" file, originally 4096 bytes sized, containig "0", the hex "0a" and the
remaing are zeroes. When I echo 1 it becames a "regular" file, containg only "1" (1 byte)

If I try to copy a 4096 bytes rearranged with an hex editor, I cannot do it (cp non permitted, rm brightness
not permitted...)

thanks for your help,
