Resetting the Series 3MX

You should never need to reset your Series 3MX. Even if an add-on application were to stop working, the Series 3MX is designed in such a way that it could not interfere with other applications, such as Data, Word, and so on.
Killing a running application
If you find that you cannot exit an application normally, you will need to “kill” the application. You can kill any application (except Time).

psion resetWhen you kill an application you will lose all the unsaved information in the file
that was open. You should therefore only kill applications in an emergency.

To do so:
• Move to the System screen, move the highlight onto the application that you wish to kill and select the ‘Kill application’ option on the ‘Apps’ menu.

• If you cannot move to the System screen, you will need to press Psion Series 3MX hard reset
to kill the application that is currently displayed on screen (the foreground process).

Soft reset - preserving your data
If, for any reason, your Series 3MX should “lock-up”, you can always perform a “soft reset”; a soft reset should restart your Series 3MX while preserving most of your data.
It is worth trying a soft reset if:
• the keys on your Series 3MX do not appear to respond, or
• your Series 3MX does appear to switch on and you are sure the batteries are good
(especially if the contrast still works but the screen is otherwise blank).
If you do need to reset:
• gently press something like an unfolded paper clip into the reset hole (above the Psion Series 3MX hard resetkey).

When you turn the Series 3MX on again it will beep, show the start-up screen again, and then the System screen. After a soft reset:
• Any changes you had made to open Sheet or Word files (or OPL programs) would be lost.
• Your other files on the internal disk will almost always be safe.
• If you had other applications installed (other than the built-in applications), the icons will have disappeared from the System screen. Use ‘Install’ from the ‘Apps’ menu in the System screen to re-install the application icons.
• Any additional file lists or application groups you had set up in the System screen will be lost, and you will need to set them up again.
• Any alarms that you had set in the Time application are lost.

Psion Series 3MX Hard reset - losing all of your data

It is possible (though unlikely) that an application failure causes the reset to lose the information on the internal disk. It could even prevent the reset from working at all. If this happens, you will have to perform a “hard reset”. To do this:
• Hold down the right-hand Psion series 3MX hard resetkey, and gently press a suitable object into the reset hole, as before. Press Psion Series 3MX hard resetto turn on, still holding down the right Psion series 3MX hard resetkey.
This will reset the Series 3MX completely, and all information in internal memory, including the internal disk, will be lost.

You may not need to press Psion Series 3MX hard resetto switch on when resetting, as the Series 3MX may turn itself on.

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.
