FYI These codes have been obtained by decoding various .apk files present in the phone firmware.

It'll NOT remove:
* Current system software and bundled applications

PS: 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.

This code is used to get information about phone camera. It shows following 4 menus:

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.

Today in this topic, I'll reveal 3 hidden modes in the phone:
* Fast Boot mode
* Download mode
* Recovery mode
WARNING: All these modes are used to flash/reset phone firmware. Think twice before entering in these modes.
Fast Boot Mode
This mode is used to flash the phone firmware using command line tools. To access this mode:
* Power off your phone.
* Press and hold Call and End Call/Power keys.
Download Mode
This mode is also used to flash the phone firmware. Mostly this mode is used by GUI tools for easier and quicker flashing. To access this mode:
* Power off your phone.
* Press and hold Volume Down, OK and End Call/Power keys.
Recovery Mode
This mode is used for recovery purposes like to reset the phone firmware. To access this mode:
* Power off your phone.
* Press and hold Volume Down, Call and End Call/Power keys.
Once the alert triangle is shown on screen, press "Menu" key to reset the firmware or press "Home" and "End Call/Power" keys to show recovery menu.
