When you sell your phone, you must return the phone to its original state by completely clearing its memory. This is necessary so that your data does not accidentally fall into the hands of the new owner of the cell.
Instructions
Step 1
Turn on your phone and delete all personal files. Clean the phone book by first copying it to the SIM card. Delete incoming and outgoing SMS messages, as well as photos and videos. After that, delete the notes and audio files saved in the cellular memory. Remove the memory card and insert it into a card reader connected to your computer. Format and paste back to mobile.
Step 2
Connect your phone to your computer using a USB cable. To sync, you need a data cable, drivers and sync software. Typically, these files can be found on the CD that is included with the package. Otherwise, you will need to connect to the Internet and go to the manufacturer's official website. Download drivers and software for synchronization.
Step 3
Install the driver and software before you connect your phone to your computer. After making sure the installation is complete, sync your mobile with your PC. Wait until the drivers are installed and make sure that the computer "sees" the phone. Go to the phone menu from your computer and delete all personal files. After that, restart your phone from your computer. Check for deleted files, then disconnect your phone from your computer.
Step 4
You can also use special codes, by entering which you will return the phone to the factory state. Use the fan sites dedicated to your phone for this. However, the best way would be to contact the technical support of the cell manufacturer. Find her contacts on the official website of the manufacturer. Request a firmware reset code by providing your cellular model and IMEI number. This number can be viewed by removing the back cover and battery from the phone. Enter the received codes and reset the cell firmware.
