make sure when using the USB method to add the files straight to the flashdrive. Do not put into a folder. When plugging in, as soon as you see see initializing press the home button. After a few seconds the USB recovery should start on it's own.

I know this is an old post but trying to get an old recovery ROM for a CP960 that came with new software, can't convert to zoom rooms, where did you download?

Thanks!
