hi funman,
i have a similar issue here.
I installed rockbox on my Clip V2 using the installation utility. I installed rockbox (latest RB version suggested by the utility) using the 2.01.35a firmware.
Everything went fine so far. I can run my Clip play files etc.
So since there is no usb support (?), my clip is not recognized any more on USB using windows (7 and Xp tried).
I also tried the utility to "find" the Clip on my USB... no success.
How can I proceed now to revert to the original firmware? (I would say I'm now a little desperate :-) )
Regards and thanxs for your help in advance...
