I can't seem to find anyone else who is having this problem, but on my Clip+, I just installed RB and got it all working nicely, and managed to connect by USB at least once to put the Classic theme on, but now, when I try boot into the OF by plugging in USB or using dual boot mode, it flashes up "Sansa" then the cloverleaf style logo, and then goes black and repeats.
EDIT: Development - now seems to not turn on at all. When plugged into USB, it is recognised as a device sometimes, but not installed successfully and at no point does the screen ever turn on.
I just plugged it in again and it appeared as a removable disk, but said it needed formatting before I could access it. I did it (probably a bad idea) and there's no change.
I'm going to try let it run flat, but with no screen I'm guessing that will take a good long time.
EDIT2: I'm fairly desperate. Are there any ideas out there at all? Any more information I could give to help, or chance that Sansa could be any help at all?
It's frustrating, because I really can't see where I went wrong; alarm bells should have probably started when the automatic installer didn't work, but I'm fairly sure I'm technologically literate enough not to have messed up the manual install.
