Reset the iPAQ H3870 and Clear Memory
Resetting the iPAQ
If your iPAQ H3000 responds slowly, stops responding as expected, or “freezes”, try resetting it. A reset causes the iPAQ H3000 to restart and re-adjust memory allocation. Unsaved data in open windows may be lost. Use the stylus to press and hold the Reset button for about two seconds.
NOTE: Do not turn off your iPAQ as it must remain on in order to reset.
If you want to clear all data from your iPAQ H3000 and return it to the factory settings, you should clear the memory.
Clearing memory deletes all data and restores the iPAQ H3000 to its default settings. Programs installed at the factory remain, while data you have created and programs you have installed are erased.
1. Using the stylus, slide open the On/Off door on the base of the iPAQ H3000.
2. Slide the On /Off switch to the Off position using the stylus. Wait about one minute, then slide the switch to the On position.
3. Close the Battery On/Off door using the stylus.
NOTE: Use CF Backup/Restore or ActiveSync to keep a backup of your iPAQ data so that if you need to clear memory, you can restore the data on your iPAQ.
Compaq iPAQ H3870 hard reset
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.
