In a desperate move to get my Treo 650 back into working condition (because it kept rebooting) I tried a Zero Out Reset today. This proved to be a bit difficult, because as stated by Palm
We made this method of zero out reset extremely awkward to perform, so that it would not happen by accident.
And indeed that’s what they did:
While continuing to hold Power, UP and HotSync, press and release the RESET button on the back panel of your device. This is very difficult to do with only one person; you may wish to hold the stylus in your mouth and use your hands to press Power, UP and HotSync.
However, as outlined in a thread on Treocentral.com, there’s an easier way to do it:
balance the Treo on the stylus, carefully hold the hotsync, power, and rocker-up buttons and then apply a slight amount of downward pressure to initiate the reset.
After many failed attempts using the method described by Palm, this did the trick for me.
