Just wait until it's ready for testing and don't mess with dualboot.S if you aren't fully self-confident.

bricked c200v2 can not be unbricked

I tried installing rockbox on my C240v2 1.0GB and ran into this issue.
I solved it by commenting out the 'Plugged into USB' check in dualboot.S and it now tries to boot rockbox, but apparently the rockbox loader fails and blinks an error code at me. Are those blink codes documented somewhere?
I can still boot the OF if I hold down right while powering on.
I followed the documentation for "Installation for Unusable" on http://www.rockbox.org/wiki/SansaAMS
I did unzip .rockbox on the rootfs of my Sansa.

Here is what I changed in dualboot.S to make it work for me:
