HP iPAQ 500 Voice Messenger Series - Resetting the Device
Sometimes you need to reset your iPAQ if, for example, it is not responding to your pressing a button or your tapping the screen.There are two types of resets.

• Soft Reset - A soft reset stops all running applications, but does not erase any programs or saved data.
• Factory or Hard Reset - A factory or hard reset clears all user-installed settings, programs, and data, and restores your iPAQ to factory settings.

Performing a Soft ResetPerform a normal or soft reset to stop all running applications, to restart the iPAQ after installing a new application, or if the iPAQ locks up.CAUTION:Make sure to close all running applications before performing a soft reset, since a soft reset erases all unsaved data in such applications.Perform a soft reset using one of these two options.

• Turn off the iPAQ by holding down the End key.1 - End Key
• Remove the battery of your iPAQ.

Performing a Factory or Hard ResetPerform a factory or hard reset when there is a need to clear all settings, programs, and data from the RAM.CAUTION:Performing a hard reset will return the iPAQ to its default settings and it loses all information (files and settings, among others) that is not recorded in the ROM. Back up all important information or data before performing a hard reset.Follow these steps to perform a hard reset and return your iPAQ to factory settings.

1. Turn off your iPAQ by holding down the End key.
2. Then hold down the center of the 4-Way Navigation key and turn on the iPAQ again while continuing to do so.1 - 4-Way Navigation Key2 - End Key
3. A confirmation screen opens asking whether you want to perform a hard reset or not. SelectYes . The iPAQ will reboot with its original factory settings.

NOTE:The applications and data present on your iPAQ before performing the hard reset can be reinstalled by synchronizing your iPAQ with a computer using ActiveSync/WMDC (Windows Mobile Device Center).NOTE:If you don't want the iPAQ playing a tune after you turn it on, create a new text document and save the document as StartUp.wav. Replace this new document with the file on your device.

Please go through following link to set up your iPAQ.This page has the links to reset different models of iPAQ.http://resetcellphone.com/solution/HP
It will be better if you can give the exact model number of your iPAQ.

Performing a Hard Reset

Perform a hard reset only when you want to clear all
user-installed settings, applications, and data from RAM
(Random Access Memory), where data and applications you have
loaded are stored.

CAUTION: If you perform a hard reset, your Pocket PC loses all data
and programs not saved in iPAQ File Store.

To perform a hard reset:

1. Press and hold down the Calendar and iTask buttons.
2. While holding down these buttons, use the stylus to
lightly press the Reset button on the bottom of the iPAQ
Pocket PC for about two seconds.
3. When the Pocket PC screen begins to fade, release the
Calendar and iTask buttons first, and then remove the stylus
from the Reset button.

Note: If you simultaneously push and hold the Reset, Calendar,
and iTask buttons for more than two seconds, the battery
disconnects. To restart the device, either plug the device into the
AC Adapter or press the Reset button again.
After performing a hard reset, you may need to reinstall
applications stored in iPAQ File Store to restore shortcuts and full
functionality.

4. The Pocket PC resets and powers on.

To return your iPAQ Pocket PC to factory settings after
performing a hard reset:

1. Tap Start > Programs > File Explorer > My Device.
2. Tap the iPAQ File Store folder to open it.
3. Tap Edit > Select All.
4. Tap and hold the selected files, then tap Delete.
5. Tap Yes to delete all file in iPAQ File Store.

(H5450 and H5455 are the same ipaq)

I had the same issues as mentioned installing TomTom Navigator version 7 onto a HP IPAQ 2415 running Windows Mobile 5. As soon as TomTom was installed the sound stopped working.

I did a Hard Reset to restore the IPAQ which got the sound back. I then downloaded the trial version of WinCE Cab Manager http://www.ocpsoftware.com/products.php?nm=cecabmgr and used this to remove the files Btcoreif.dll and Btsdkce30.dll from the TomTom installation CAB. I saved the cab and then ran this again and it installed perfectly and I still had sound. Hope this offers a solution for anyone still having a problem.

hard reset: Button 1 and 4 and press reset button with stylus
