Sony HCDX1 STUCK IN DEMO MODE


I don't have a Sony HCDX1, so if this doesn't work, please do not rate me down.

Push the PLAY and STOP buttons (at the same time) and hold them for about ten seconds. This should get you out of DEMO mode.

Power the unit off, then back on. If the display now says LOCKED, then press the PLAY and STOP buttons (at the same time) again to unlock.

If this does work, please rate it Solved, so others can use this solution. Thanks!

My sony Mp3 is not working


I tried something and it seemed to work ( though how long it will lst I don't know ).

1. Let the battery go dead
2. Put the player in the USB port
3. Update with latest Flash Driver ( check the format option )
4. When finished, remove from the USB port WITHOUT disabling the port through Windows ( just pull it out )
5. Hold down the play button and keep it held down.
6. Navigate to Settings.
7. Go to Restart option and click ok. You have to be quick here since you have to release the Play button. Once you get to the next level , keep the play button pressed or else it will shut off
8. Once it says restart is complete, press power button to shut it off.
9. If you have enough power, give it a try otherwise plug it back in USB port for about 5 to 10 min to get a charge.
10. Remove from USB port the same way as before.

Lock and Demo Play Display


while the demo is playing you must press "Play"and "Stop" buttons, then display shows DEMO OFF and you can now take the DEMO CD out.
In some models you need to turn off the power and turn it on while pressing the EJECT Butoom.
