Occasionally, you will need to reset your HP Jornada 688 Handheld PC. For example, you may need to reset your HP Jornada after you restore data from your desktop PC or when the operating system stops responding. There are two methods of resetting:

  • Soft reset : A soft reset (also called warm boot) is similar to restarting your desktop PC. It restarts the operating system and preserves any saved data.
  • Factory default reset : A factory default reset (also called hard reset) restores your HP Jornada to its original state, erasing all information you have entered. To ensure the safety of your information in case a factory default reset is necessary, you should regularly back up your data to your desktop PC + ActiveSync or to a CompactFlash or PC Card (using the HP Jornada backup application).

Performing a soft reset

Perform a soft reset after restoring data from a backup file or when your HP Jornada appears to be frozen or locked up.
To perform a soft reset

1. Disconnect the sync cable and/or the telephone line from your HP Jornada, or remove it from the docking cradle.
2. Use the stylus to press the Reset button. When you perform a soft reset you will lose unsaved data in all open documents or programs.


Performing a factory default reset

Perform a factory default reset only when your HP Jornada does not respond to a soft reset. A factory default reset will erase all data you have entered, including all files, system settings, and programs you have installed. If you have forgotten your primary and reminder passwords, you will also need to perform a factory default reset. Performing a factory default reset erases all files, programs, and appointments you have entered. You can restore only data that has been backed up to your desktop PC or to a PC Card or CompactFlash Card.

General advice: Before you buy a new cell phone or new tablet, please try the following procedure to repair your device in a software way. First charge your battery, backup your important data if possible and in most cases take out SIM and SD card before doing factory reset. It is impossible to recover your data after doing a hard reset, so online backup is always important. For all of your data, a backup should be done on an external device, hard drive, raid system or media. With or without insurance, if your cell phone lost, damaged or stolen at least your invaluable data is backed up in a safe place. If you are about to sell your phone and you want to wipe your personal data, or if your phone affected with virus you have to do a hard reset. In some cases, you can delete the forgotten password or lock pattern from your device as well. All information is for devices with stock based ROMs. If you are using rooted device, always back up your EFS folder first, containing your IMEI info, etc.! Please also note, that a hard reset operation will not unlock your mobile phone's SIM lock or network lock, but it will remove the unlock pattern, remove the user password or PIN password (NOT the SIM card's 4 digit PIN code). Also note that the firmware version will not be affected in any way, it will not be downgraded, it will remain the same you are using and if you have rooted your device, root privileges remain also unaffected.
