If the phone is not charging nor allowing you to turn it on suspect the battery. If it is charging but not allowing you to turn it on suspect a fault on the power supply board of the phone. Hope this helps.

I just bought a used ZTE N9130 cell phone when I charged / powered it up the screen is pattern locked. How do I factory reset this phone ?


To perform a hard reset, or factory reset, then there are a number of methods to try:

1) From the home screen, press Menu - Settings - Privacy - Factory data reset - Reset phone. It may ask for a password. Then select Erase everything

If the phone is totally unresponsive, even after a reboot, then try the following methods.

2) While the phone is turned off, press and hold the Volume Up and Volume Down buttons together. Then, while holding these, press and release the Power button (keep holding the volume buttons). The phone should turn on and a menu will appear. Press the Volume down button to navigate to the Recovery option. Press the Volume Up to select (if that doesn't work, use the Power button to select). A yellow triangle and an Android logo will appear. Press the Volume Down and Volume Up button together and a recovery menu should appear. Use the Volume buttons to move to the Wipe data/Factory reset option and then press Power to select. Again, use the Volume Down key to choose Yes and press the Power button again to select.

3) While the phone is turned off, press and hold the Volume Down button. Then, while holding, press and release the Power button. A menu should appear. Use the Volume down key to go to Clear Storage. Use the Power button to select the option. Then when asked to confirm, press Volume Up for Yes.

4) While the phone is off, press and hold down Volume Up + Home + Power buttons at the same time. Then release the buttons when you see the Logo. Use the Volume Down button to go down and the Home or Power key to select. Choose the Wipe data/Factory reset option. Then Select Yes to delete all user data. Then choose to reboot the phone.

5) A final method is to enter the code into your phone's dialer: *2767*3855# This method will not give you an option to reverse the process, so be careful! This method will only work if you can boot into your phone. - See more at: http://www.phonetipsandtricks.com/tips/zte-warp/how-to-hard-reset-factory-reset-31/#sthash.9JNbyTkc.dpuf

Sound like you have to restore the phone and if still persist..phone replacement if battery is good.If you have an SD card in phone remove it please. Make sure your picture and contacts are backed up to SD card. This will take phone back like new.
    • Turn off the phone.
    • 2 Hold down the "Volume," "Power" and "Home" buttons at the same time. Continue holding the buttons until the 3-D Android logo and a menu of system options appears on the screen, and then release the buttons.
    • 3 Press the "Volume" button to scroll through the menu options and highlight "Wipe Data/Factory Reset." Press the "Power" button to select the option.
    • 4 Use the Volume button again to highlight "Yes, Delete All User Data," and then press the "Power" button. The Event deletes all your personal data and settings from the phone and then returns to the first menu.
    • 5 Highlight "Reboot System Now," and then press the "Power" button to restart the phone. After several minutes, the Event starts up and opens the main screen, giving you the option to set up the phone just as if it were brand new.

Power button wont turn


Soft reset by removing the battery, wait 20 seconds and reinsert.

If this does not solve the problem...
1. Remove the battery, wait for a few seconds, then reinsert the battery to turn off your Merge.
2. Press and hold the VOLUME DOWN button, and then briefly press the POWER button.
3. Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button.
4. Press VOLUME DOWN to select FACTORY RESET, and then press the POWER button.

If none of this works, get a new phone, hopefully you have the insurance.

You can restore the phone to factory default but it will erase all your data.

  1. With the phone turned off, press and hold the VOLUME UP and VOLUME DOWN buttons, then press the END/POWER button shortly and release it.
  2. Release the VOLUME UP and VOLUME DOWN buttons.
  3. Press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.

Iphone want turn back on


hi...i already written something about that therefore i have just copy and paste it... --> If you have some problems with your iphone like it wont turn on or it wont react even though you tried things like hold both buttons simultaneous or some other stuff and it dont helps....then there is the last possibility before you have to go to an apple store....and hope that they fix or replace it! you have to bring your phone to the DFU modus...for it follow the next steps: start itunes and plug-in your iphone even if it is turn off or it just shows the apple logo.... further press down the power button for about 3 second, then press the home button WITHOUT release the power button and hold both simultaneous at least 15 second.... finally release the power button and continue hold the home button for about 30 seconds... now the iphone should be detected by itunes. it ought to recommend to restore it to the factory defaults! after that you iphone should works correct again... hope my instructions are useful and let me know if it works on ur iphones!
