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.

Hi. You need to HARD reset your phone.
To perform a hard reset (Full Reset) press and hold the left SOFT KEY and the right SOFT KEY, and at the same time, use the stylus to press the RESET button at the middle left side of your device.
Release the stylus, but continue pressing the two SOFT KEYs until you see the following message on the screen:
This operation will delete all your personal data, and reset
all settings to manufacturer default. Press Send to restore
manufacturer default, or press other keys to cancel.
Release now the two SOFT KEYs, and then press the TALK (Send) button
Thank you for using fixya

Hi,

There are 2 types of resets on a nokia phone. A soft reset and a hard reset.

1, Soft reset, this option restores the .ini files from the ROM. Does not erase data (photos, videos, documents) or applications from a third party. Key Code *#7780# (type this combinations on the keyboard on the mobile phone.

2, Hard reset, this option restores the original operating system from the ROM. Formats the C: partition and deletes all data including the memory card. Key Code *#7370# (type this combination on the keyboard on the mobile phone.

There are three main types of Reset that apply to the Blackberry. These are listed in order below. Instructions for Blackberry Pearl are slightly different - see bottom section of the Tip.

1) Soft Reset - simply press the ALT+RIGHT SHIFT(CAP)+DELETE keys.

This reset stops all applications that are running on the Blackberry and will help if you are having problems connecting the device to computer. This reset will not erase any information from your device.

2) Double Soft Reset - this reset is almost equivalent to a full hard reset. First perform a Soft Reset as outlined in Step 1.

As soon as the screen is no longer black - repeat the steps once again exactly as before.

This takes you to another screen showing an hour glass. Allow the device to reset. This helps if the device has suffered a more serious error. Be aware you may loose some information from your device. A backup is advised prior to proceeding if at all possible.

3) Hard Reset - this is the full blown reset and will fully reset the device to help resolve critical errors with software or hardware. Again back up important information before proceeding if possible.

Note: For RIM models 850, 857, 950, or 957, you must insert the end of a paperclip or similar blunt object into a small recessed hole on the back of the unit and depress the switch inside. The device will reboot and be hard reset.

Other Models: With the device turned on - remove the battery for 30 seconds or more. Now replace the battery. The device will reboot and be hard reset.

Blackberry Pearl: To reset to factory defaults enter 'Options' from the main menu. Scroll to Security Options and press the trackball. Choose 'General Settings'.

Press the left soft key, then scroll to "Wipe Handheld" with the trackball and press the trackball. To initiate the factory reset, your phones security code may be required in order for the process to complete. Your phone will now be restored to its original settings on leaving the factory.

A hard reset can be achieved with the Pearl in the same way as outlined at Step 3 by removing the battery.

Be aware that resets such as these may erase data, such as contacts, ring tones, pictures, text messages and stored Internet files and emails. Make sure to back up important information beforehand if at all possible. You can obtain software to back up the device to your computer directly from Blackberry right here.

Hope this Tip helps. If so please do leave a vote for the solution.

Thanks.








i hope ,i will help you ,thanks for trusting fixya...

A reset of a BlackBerry smartphone does not delete any settings or data.There are two options for performing a reset: a hard reset and a soft reset. A hard reset involves physically removing the battery from the smartphone and then reinserting it. To perform a hard reset, complete the following steps:
1) Remove the battery cover from the back of the BlackBerry
smartphone.
2) Remove the battery, and then reinsert it after a few seconds.
3) Replace the battery cover.

try this for soft reset

12345 is a standard code and 00000, but if you change it and you have forgotten your unlock code, you'll just have to reformat it

key combination which is used to hard reset the phone (similar to #*7370). It is useful in some cases, for example when the phone cannot reboot.

The trick is
Switch off the phone.
Hold down the following three buttons: Green (call answer) button, * button, and ‘3′ button
While holding these buttons, press the power button and switch on the phone
When the message ‘Formatting’ appears on the screen, release all of the buttons...

reformatting your phone will delete all your data and also will restore all the defaults of your phone, and any corrupted application will be reinstalled, but if the formating doesn't work, you'll just have to re flash it, the safe way is to go to a near repair shop of your phone and have then to re flash your phone,

You can do a Hard Reset which will reset your phone to its original factory settings. Any applications or personal data you put on the phone since owning will be lost. You can recover personal file if you have backed them up, of if you have License 'Key' numbers you got when you purchase them. Some App suppliers will have you an record and will email your Lic # if your email has not changed since purchase.

To Hard Reset, turn off your phone and then turn it back own while holding down both left and right soft keys till you get a screen asking if you want to Reset it. Another Hard Reset method, if you can get to Start Menu/Accessories folder when phone is powered, is choose Clear Storage and clear the storage. This may not work on some phone models, but note this method will also reset your phone to 'as purchased' state, with all stuff you added since removed.

Note a Soft Reset is the same thing as just turning phone off then back on as normal. It does nothing but re-power your phone, but a Hard Reset recovers your phone operating system from phones MFG ROM and resets it back to original as purchased state.

It seems to be os is corrupted so try to reset to factory setting...
