Ben and everybody,
The multiple-click problem prevented me from trying the acoustic

would be interested in it, too:

Exactly. One of such sillyness (with educational value in mind^^;)

I tried to do clean install of 643 and it failed. Actually, it worked
for the first time. Then, I realized that I forgot to put Q2D05
firmware on my USB memory. So I put the .rom file and tried the clean
installation again. Then during the boot process I got:

From what version should I try this? Naturally my B4s are loaded
