How to recover deleted data?

Unfortunately, we may delete some of the useful files from our system. In those cases, there is a possibility to retrieve back the lost data. Even in some cases, we may format our hard disk or the USB drive. In all these cases, we can retrieve back the lost files.

1. Recuva -------It is a free software under GPL license.
                          http://www.piriform.com/recuva

2. File Scavenger-------it is offered in two ways: evaluation version and payed version.
                                    But, the evaluation version is more than sufficient. Here, we can get the
                                    opportunity to preview the files being recovered.
                  http://download.cnet.com/File-Scavenger-Data-Recovery-Utility/3000-2094_4-10028488.html

These two are more than sufficient ....

The more timely you use, the more the deleted files that can be extracted with good quality.

All the best! go and Try!!!

Secret (ussd) Codes For Android Mobile Phones

1. Complete Information About your Phone

*#*#4636#*#*
This code can be used to get some interesting information about your phone and battery. 

Usage statistics

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
System and application data and settings
Downloaded applications
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

*2767*3855#
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.

WARNING: Never use the first option otherwise your phone camera will stop working and you'll need to take your phone to service center to reinstall camera firmware.

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.
You can change this action using this code. You can enable direct power off on this button so you don't need to waste your time in selecting the option.
