Do a hard reset. Hold the on/off button while simultaneously pushing reset button on back. Keep on/off button pushed until Palm Powered screen appears. This erases all data and gives language options.

When performing a hard reset on the Palm Centro, you hold down the power button as you insert the battery, and then release the power button when you see the second Palm logo.

Just had to do a hard reset myself and it's not straight forward! While holding down the power button, BRIEFLY press the reset button on the back of the palm. DO NOT RELEASE the POWER button until you see the GRAY screen with the Palm logo (not the first screen with the palm logo). That should start the hard reset for you.
