Unfortunately no. The RB needs power from its main battery in order to be updated, but the USB port is inside the battery compartment making it impossible to use both a USB and battery at the same time (it's a major design flaw in the RB). There are update files for the RB on the forums and you can update your RB using a 2GB micro SD card if you are having problems with it, but there is no way to reset your Pleo RB back to a baby and the reset files on the forums only intentionally brick your RB so it can be updated from a clean slate in case there is something seriously wrong with the firmware.
