Hi Again
Question 2 :
My ZOOM have vers. 2.10 and I'll like to update to 2.40.
I've downloaded the possibility > For the system version "VER=1.20" or later > from >ZOOM's webpage.
It ends with a file called SYSTEM.BIN (i'm a Mac PRo user)
on the webpage is an > how to update the system software. I've followed point 1 > point 2 > point 3 says copy the SYSTEM.BIN file into the root directory of the SD card.
Here i'm in doubt. Does that mean on to the SD card beside the other folders at the top off the hierarchy or into the folder SYS on the SD card.
Either way it doesn't work for me because next passage says.
4. Input the SD card into the H4. Turn on power to the H4 while holding down the bottom (INPUT MENU ) of the (MENU) key.
I've tried all possible way of touching this button
The H4 doesn't start with the screen suggested by ZOOM : Version up?

What to do ?
