Troubleshooting for Nokia Asha 200

If you have forgetten or you have lost the lock code or security code, try first the default lock code 12345. If it is not accepted, contact the nearest Nokia Care point to unlock your device. To find nearest location to you, go to your local Nokia website, and navigate to Support > Contact us.

Contact your operator immediately:

1. To block your SIM card.
2. To block your Nokia device (HW, IMEI code) to prevent it being used in the operator networks with any other SIM cards.  Note that not all operators provide this service (blocking device).

Note: Nokia customer support doesn't have the possibility to block the SIM card or the device, or track a stolen device.

To minimize the risks caused by the theft or loss of the device, there are some security features which you can enable in your device:

1. If your Nokia device supports phone autolock or security keyguard and you have turned it on, the phone cannot be accessed without entering a correct lock code. When enabling the autolock feature, it is important that you change the default lock or security code (12345) to your own lock code and don't forget this code.
2. Some Nokia devices support also remote locking. If you have enabled this feature, you can send a pre-defined text message to your device and lock it remotely. The device is locked if it is switched on and has your SIM card in it.

Note that the phone autolocking and remote locking cannot be enabled after the device has been lost, so it is important that you enable these security features already when taking the device in use.

Select Menu > Settings > Rest. factory sett. (or Reset device or Restore factory sett. or Rest. fact. sett.).

1. To reset only preference settings, but keep all personal data, such as contacts, messages and media file, select Restore settings only (or Restore sett. only or Settings only).
2. To reset all preference settings and delete all personal data, select Restore all (or All).

3. Enter the security code before the restore. If you have never changed your security code, then enter the default code 12345. If your phone still requests a security code or if you have forgotten it, please bring it to the nearest Nokia Care point for inspection.

Your Nokia device requests PIN (Personal Identification Number) and PUK (Personal Unblocking Key) codes to protect your SIM card and device against unauthorized use. Note that all PIN and PUK codes are provided by your network operator. Nokia is not able to provide you PIN or PUK codes.

Please note the following:

• When your insert your SIM card and boot up your device for the first time, you need to enter the PIN code. For security reasons it is recommended to change it to your own code, instructions on how to change the PIN code in your device is provided in the user guide or Nokia web site. If the PIN code is entered incorrectly multiple times, your device may request a PUK code to futher validate the user's identity and to unlock and change the blocked PIN code.
• The PIN2 code is a PIN code which acts as a second layer of protection for certain features of your phone.  If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code.

If you have forgotten or simply do not know the codes, you must contact your Network Operator for assistance. However, if you have already contacted but the code does not work, you should consider getting a new SIM card from your Network Operator.

If your phone is unresponsive, or it gets stuck showing Nokia logo, then try this: Press and hold both the Volume down and the Power keys for 15 seconds. This should get your phone to restart properly again. If this does not help, then follow next steps to perform OS reset.

Warning: Resetting your phone will return it to the same state it was in the first time you turned it on. All your personal content in the phone, including text messages and apps that you been purchased and downloaded (may be re-downloaded again) will be erased, and the phone will be restore to the factory settings.
Here are two options to follow, depending on whether you can access your phone's Settings screen or not.

Option 1: About menu

• Use this option if you can access your phone's settings.
  
• This option warns about data loss.

On the Start screen, swipe left, select Settings > About > Reset your phone.

Option 2: Hardware key combination

• Use this option if you forget or lose the password.
• Use this option if the phone fails to fully switch on when pressing the power on key.
• Note: No warning about data loss!
