I want restoret is my mobile is not working

Hi Sai,

Depends on the model and make. Typically, there are steps to reset it completely. Please try the following steps and see if they work.

1. When the phone is powered off, press and hold the Volume Up and the Volume Down keys both at the same time, then press and hold the Power key until a test screen that shows some available options appears, usually takes about 15-20 seconds. When that screen pops up you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights FACTORY RESET then press the Power key to select it.
2. Power the phone off all the way, press and hold the Volume Down key and press than release the Power key, still holding the volume down key for about 10-15 seconds. When you see some additional options pop up on the screen you can let go of the keys.
Press the Volume Down key to navigate down through the options until it highlights the reset option; it usually says FACTORY RESET, then press the Power key to make the selection.
3. While powered off, press and hold the Home key, while continuing to hold the home key power the device on by pressing the Power key.
Once the Android Recovery screen appears release the Home key, then while on the Android Recovery screen, press the Volume Up and Volume Down keys both at the same time.
If/when you're on the Android System Recovery screen release all the keys, and then use the Volume down key to navigate down to the "wipe date/factory reset" option. Once it's highlighted press the Power key to select it.
Once you see the "Confirm wipe of all user data?" Press the Volume down key to highlight "Yes-delete all user data", then press the Power key to select it.
4. Power the device off, then press and hold the Home key and press and release the Power key (while still holding the Home key).
From the Android Recovery screen, press the Search key.
Tap to select wipe data/factory reset then select Ok (located in the lower left of the screen). Note: if screen is not responsive use the Volume keys to scroll and the Camera key to select.
Select Yes - delete all user data, and then select OK (again lower left).
Select "reboot system now" and press OK.
5. This is becoming a common hard reset method and can be used to factory reset Samsung's more recent Galaxy smartphones such as the Samsung Galaxy S III, the Samsung Galaxy S4, the S5, the Samsung Galaxy Note the Note II and Note 3, etc.

With the device powered off press and hold the Volume Up key the Home key and the Power key all at the same time.

When the phone vibrates (or you see the GALAXY Logo) release the Power key but continue to hold the Volume Up and Home key.

Continue holding the Volume up and Home key until the "Android system recovery" screen appears.

Use the Volume buttons to scroll to and highlight the "wipe data/factory reset" option, and then use the Power key to make the selection.

Once the factory reset is finished you may use the Volume and Power keys to highlight and select the "Reboot system now" option and the hard reset will be complete and your cell phone will be nice and squeaky clean.

How do i hard reset my virgin mobil htc 3g\4g

turn off the phone, hold the power and down volume buttons, then using the volume up and down to scroll and the lock key to select, go to recovery. wait a little and then a phone with a red triangle and an exclamation mark on it should appear(some of the HTC phones will not get this image, if after 60 seconds it does not appear, proceed to the next step), hold the volume up button then tap the power key, then using the volume keys as scroll again select factory reset and say yes. this will erase all the data on the phone though.

How can i connect bluetooth ce0681 to nokia n95

All these given solutions are not catering your problem unfortunately; because your problem seems to be the following "You are not at all able to find your bluetooth headset from your phone, pairing is a far off thing" right?

So, here is the simple solution that no one has given here and on other sites (I myself was confused, but finally found it out):

1. Turn bluetooth of your Mobile on.
2. Put it into "shown to all" mode.3. Now pick your bluetooth device, and simultaneously click on the multifunction key (The middle one that blinks) and the "+" volume key for around 6 seconds or more; you'll see that blue blinking light will become static (and it means that your bluetooth device is now "Searchable" by your phone).
4. Start "Pair new device search" from your Mobile, and your Phone will find the bluetooth device.5. It will ask you for a passcode, just enter 0000.6. Pair both devices now.7. The static blue light (Which became static when you pressed the middle multifunction key and "+" volume key together for some seconds) will now start blinking again (in a 3 sec interval approximately).
Your handsfree is now connected, do a test call and confirm.
In case you find any volume problem, then know that the default volume after connecting a bluetooth handsfree is at low level, so just increase it using your Phone's volume keys/ controls and it shall be all fine.
Vote up if it helps, it is the genuine solution of this problem though; I tested it several times. :)

PS: I'm writing this while logging off in haste, pardon any spell/ typo mistakes. :P
