*#*#4636#*#*


Phone information

2. Factory data reset

*#*#7780#*#*

This code can be used for a factory data reset. It'll remove following things:
   •Google account settings stored in your phone

It'll NOT remove:
Current system software and bundled application
SD card files e.g. photos, music files, etc.
Note: Once you give this code, you get a prompt screen asking you to click on "Reset phone" button. So you get a chance to cancel your operation.




3. Format Android Phone

Think before you give this code. This code is used for factory format. It'll remove all files and settings including the internal memory storage. It'll also reinstall the phone firmware.

Note: Once you give this code, there is no way to cancel the operation unless you remove the battery from the phone. So think twice before giving this code.

5. End Call/Power


*#*#7594#*#*

This one is my favorite one. This code can be used to change the "End Call / Power" button action in your phone. Be default, if you long press the button, it shows a screen asking you to select any option from Silent mode, AirPlane mode and Power off.

 USB  Tethering                

 

Your Android mobile phone can behave as an external network interface usbN, connected via the USB infrastructure. The usbN interface is in turn connected to the mobile phone LAN, providing dhcp server, DNS server, gateway and so on.

 That's how your mobile phone can provide an Internet connection to another device.

Android phones are already equipped to provide this functionality. Simply connect the USB cable and go to Settings -> Wireless settings -> Tethering -> Tethering USB.

What you need is some kernel and network configuration on the other side (e.g. your laptop).

 

 

USB Tethering with Windows XP/7/8  

 

USB Tethering with Windows XP

Windows XP contains the drivers you need to take advantage of USB tethering, but you must install a configuration file before connecting your phone to your Windows XP computer, to instruct Windows XP how to configure itself to use those drivers.

1. Download the following configuration file (tetherxp.inf) to your Windows XP computer. Typically, you can right click on the link and choose "Save As". (If your browser appends .html to the file name, you will need to edit the name to remove the .html extension.)
2. Use the USB cable that came with your phone to connect your phone to your computer.
3. On the Android phone, press Home, press Menu, and touch Settings to open the Settings application.
4. Touch Wireless & networks > Tethering & portable hotspot.
5. Check USB tethering.
6. When Windows XP’s New Hardware Wizard opens, select No, not at this time and click Next.
7. Select Install from a list or specific location and click Next.
8. Click Browse to browse to the directory where you installed the configuration file you downloaded in Step 1 and click Next. Windows XP uses the configuration file to configure itself to support USB tethering with the Android phone.
9. When Windows XP finishes installing the software for Android USB Ethernet/RNDIS, click Finish

           Note: Make sure that all of your phone drivers are installed on the system .
