Soft Reset

If your Xperia Z Series is frozen and not responding when pressing on buttons or tapping the screen, try a soft reset. A soft reset will not wipe any data from the device.

1. Open the SIM card door cover on the side of the phone.
2. Use the end of a paper clip to press the small "OFF" button until the device vibrates. The Xperia will shut off, allowing you to restart.

Hard Reset

If you wish to return your Sony Xperia Z Series smartphone to factory default settings, a hard reset is the answer. If you perform a hard reset, it will wipe all data and settings from the device. You may wish to perform these steps if you've been experiencing lock ups or other types of malfunctions, or if you will no longer be using the device.
Note: If you think you may need any information stored on the phone in the future, be sure to backup the data.

Option 1 - Hardware Buttons

1. With the device powered off, press and hold "Power" and "Volume Down".
2. When the "Sony" screen appears, release both buttons.
3. The Recovery screen will appear. Use the volume buttons to toggle the selection to "Factory Reset", then press "Power" to select.
4. Use the volume buttons to toggle the selection to "Yes", then press "Power" to select.

Option 2 - From Android OS

1. Open "Settings".
2. Select "Backup & reset".
3. Tap "Factory data reset".
4. Select "Reset phone".

The Sony Ericsson Xperia Z Series will then go through the process of formatting the memory. Wait for it to restart and factory default settings will be restored.

When you receive your email with your unique Sony Ericsson unlocking codes, you may see there's actually more than one code, as some models require more than one code to unlock them fully. However, for simplicity, we do aim to send you a single unlock code, which will be your network unlock code (known as the NCK).

(See below for more details about code formats and more - Please read all before you start unlocking?)

6. Wait approximately 5 seconds.
7. The phone will display 'Network' and a picture of a closed padlock.
8. Press Select.

Code formats you may receive for Sony Ericsson models:
Wherever possible we'll try and send you just a single unlocking code to unlock your Sony Ericsson.
However for certain models we may need to send you more than one code, even if you don't use them all.

It would be a sting of codes as per this example:

CCK: 0984118391686835 or 0984118391686835
ESCK: 0000000000000000 or 0000000000000000
NCK: 4176979876474847 or 4176979876474847
NSCK: 3908320398047435 or 3908320398047435
PCK: 2061751224321908 or 2061751224321908
SPCK: 9960493992337231 or 9960493992337231

Note: The NCK (Network unlocking code) is the main and usually the only one you'll need.



Please note:
- If you see the message 'NCK: (0)' or 'Not Allowed', this means the phone is hard-locked. The phone cannot be unlocked because there has been more than 5 wrong unlock attempts.
- If your Sony Ericsson has a Joystick, then you must press the DOWN Arrow instead of the LEFT Arrow. DOWN Arrow meaning Joystick downwards
