Abstract
Methods to remove data from a mobile device, such as a smartphone, a smart watch, a tablet, or the like include stepwise verification of operation of hardware components of the mobile device prior to using a software tool to erase the data from the mobile device.
Claims12
A method to completely erase data from a mobile device, the method comprising:
- (a) manipulating the mobile device to place the mobile device in an “on” state;
- (b) for a condition where the mobile device fails to power on after step (a), connecting the mobile device to a charging device via a charging connector;
- (c) for a condition where the mobile device fails to power on after connecting to the charging device, disconnecting the mobile device from the charging device, cleaning the charging connector, and reconnecting the mobile device to the charging device via the charging connector;
- and
- (d) determining a charging condition of the mobile device after reconnecting the mobile device to the charging device, wherein:
- (i) the mobile device is failed when a determined charging condition is that the mobile device fails to charge;
- (ii) the mobile device is charged for a predetermined amount of time when the determined charging condition is that the mobile device is charging;
- wherein, the predetermined amount of time is between 40 and 50 minutes;
- (e) after charging the mobile device for the predetermined amount of time, completely erasing, by an erasure software tool of an application of a computer connected to the mobile device via a mobile device interface, data from the mobile;
- wherein the software erasure tool completely erases the data from the mobile device in a manner such that the data is completely removed;
- (f) when the erasure software tool fails to completely erase the data from the mobile device, connecting a device firmware upgrade (DFU) dongle to the mobile device, the DFU dongle configured to override a normal boot sequence of the mobile device and place the mobile device into a recovery mode independent of a user interface of the mobile device, and using the erasure software tool to clear the data of the mobile device while in recovery mode.

A method to completely erase data from a mobile device, the method comprising:
- disassembling the mobile device;
- connecting the mobile device to a known good power supply;
- checking if the mobile device powers on;
- for a condition when the mobile device powers on, checking if a battery of the mobile device charges;
- for a condition when the mobile device charges, using a software tool to completely erase, by an erasure software tool of an application of a computer connected to the mobile device via a mobile device interface, the data from the mobile device;
- wherein the software erasure tool completely erases the data from the mobile device in a manner such that the data is completely removed;
- and
- for a condition when the mobile device does not power on, replacing a charging connector;
- and
- when the erasure software tool fails to completely erase the data from the mobile device, connecting a device firmware upgrade (DFU) dongle to the mobile, the DFU dongle configured to override a normal boot sequence of the mobile device and place the mobile device into a recovery mode independent of a user interface of the mobile device, and using the erasure software tool to clear the data of the mobile device while in recovery mode.

A method to completely erase data from a mobile device, the method comprising:
- disassembling the mobile device;
- disconnecting a motherboard from the mobile device;
- connecting the motherboard to known good compatible circuitry;
- checking if the motherboard connected to the compatible circuitry powers on;
- for a condition when the motherboard powers on, checking a charging operation of the motherboard;
- for a condition when the motherboard powers on and the charging operation is operating, completely erasing, by an erasure software tool of an application of a computer connected to the mobile device via a mobile device interface, the data from the motherboard;
- wherein the software erasure tool completely erases the data from the mobile device in a manner such that the data is completely removed;
- and
- for a condition when the motherboard does not power on or the charging operation is not operating, physically destroying the motherboard or a memory chip on the motherboard;
- and
- when the erasure software tool fails to completely erase the data from the mobile device, connecting a device firmware upgrade (DFU) dongle to the mobile, the DFU dongle configured to override a normal boot sequence of the mobile device and place the mobile device into a recovery mode independent of a user interface of the mobile device, and using the erasure software tool to clear the data of the mobile device while in recovery mode.
