My rio used to say upgrator and now its not turning on at all.
I think when you hit the on/off power button (on top near outlet for headphones) AND hit the menu button (on side below volume dial) at same time...it puts the Rio CE2100 into "Upgrader" mode aka "Recovery" mode.
From what I've found online, basically, the firmware to the device is deleted. Trying to reinstall firmware, or reflash the device is nearly impossible. The tiny hole near the earphones is for resetting the device--use a needle (about the only thing that will fit-ouch)...but that only lets you turn it on/off if u get stuck. The tiny hole on face near display is where audio recording mic WOULD be if Rio CE2100 had one.
If ANYONE knows how to escape "Recovery mode" or "Upgrader" mode please share. This is a common final result for many owners of this otherwise great mp3 player.
There is some notation in online help site that says ce2100 requires 500mA from USB and says u can go to Device manager, check ur USB Root Hub, check Power tab to see how much power is being supplied to the device. Mine said 100mA, and doesn't work...but I don't know how to resolve this. =) Maybe tomorrow...or just wait for sales post-christmas. =)
