Data-Recovery-Proof Flashing Guide with Illustrations315

If you're looking to completely erase your device's data and make it unrecoverable, then a data-recovery-proof flashing is the way to go. This method involves overwriting every sector of your device's storage with random data, making it virtually impossible for any data recovery software to retrieve the original data.

Here's a step-by-step guide on how to perform a data-recovery-proof flashing:

1. Gather the Necessary Tools
A computer with a USB port
A USB cable
A data-recovery-proof flashing tool (e.g., dd)
An image of the operating system you want to install (e.g., a factory image)
A blank USB drive (at least as large as the image you want to install)

2. Prepare the USB Drive

Use a tool like Rufus or Etcher to flash the operating system image onto the USB drive. Make sure to select the "DD" mode when flashing the image.

3. Connect the Device to the Computer

Turn off your device and connect it to the computer using the USB cable.

4. Boot into Recovery Mode

The method for booting into recovery mode varies depending on the device. Generally, you can do this by holding a specific key combination while the device is booting up. Consult your device's documentation for the specific key combination.

5. Wipe the Device

Once you're in recovery mode, use the following command to wipe the device:```
dd if=/dev/zero of=/dev/block/bootdevice bs=4096
```

Replace "/dev/block/bootdevice" with the actual device node of your device's storage. You can find this by running the following command:```
lsblk
```

6. Install the Operating System

Once the device is wiped, you can now install the operating system from the USB drive. To do this, use the following command:```
dd if=/path/to/ of=/dev/block/bootdevice bs=4096
```

Replace "/path/to/" with the actual path to the operating system image and "/dev/block/bootdevice" with the actual device node of your device's storage.

7. Reboot the Device

Once the operating system is installed, reboot the device. The device should now be data-recovery-proof.

Additional Notes* This method will erase all data on your device, so make sure to back up any important data before proceeding.
* The time it takes to complete the flashing process will vary depending on the size of your device's storage.
* If you're not comfortable with using the command line, there are several graphical user interface (GUI)-based tools available that can help you perform a data-recovery-proof flashing.
* If you're still concerned about data recovery, you can use a physical destruction method to completely destroy the device's storage.
