There are 3 methods by which we can erase the content from smartphones using Coolmuster software.

Method 1 – Removing Messages on Android permanently

Most people use factory resetting or the primary deletion feature of their android phones to erase data which do not delete the content permanently. The links to the deleted files can be discovered with the help of data recovery software.

With Coolmuster android eraser, the data is permanently deleted with just 1 click. You can create back up of the important files if you want to reuse them. Let’s see what steps we need to follow to use Coolmuster:

  • Download and install the database on your PC. Connect the mobile to the PC using a USB or Wi-Fi connection. For using a USB cable, you’ll have to enable USB debugging on the smartphone.
  • After the connection is set successfully, the eraser automatically starts to install the drivers in the handset. In some android versions, prompts pop up and the user has to click the “Install” button to install the drivers for the device.
  • For version 4.2, click “Ok” or “Allow” so that the PC can access the device to which it is connected.
  • Now the eraser software can access all the information on the phone, we can start erasing data by clicking the “erase” button. Ensure that the connection is not disturbed until the deletion process is completed.
  • You can choose between the security levels according to your needs. For fastest deletion select low level.
  • Type your choice on the delete button on the blank space and press ok to confirm.
  • After erasing the files, Coolmuster continues to overwrite all the data and files on the phone.
  • After completing both erasing and overwriting, restore the android to factory default settings to clear system data and settings on the phone.
  • After the completion of the whole process, the text messages are permanently deleted.

Method 2 – Removing messages via delete option (not permanently deleted)

The phones have the “Delete” button which helps us delete data selectively. Long press the particular message and click on the “Delete” button. However, the messages are not permanently deleted from the phone and are recoverable. We can also use third-party tools for the deletion of data.

Method 3 – Erasing text messages by Factory Reset (50% Recovery possible)

The factory resetting resolves system crashing issues and also deletes the phone’s data. After deleting, the device goes back to the original settings.

  • Click the Home button.
  • Tap the Settings icon.
  • Choose the option “Backup and reset”.
  • Go to the “Factory data reset”. Select the option “Reset phone”.

While using factory reset, the users can’t select the files they have to erase and those not to erase. Here also the messages are not permanently deleted. A third-party tool can be used to check whether the links can be restored after the restoration of the factory settings.
