Mark_M 3 Posted January 10, 2022 Unplug the power from the DVR. Open the DVR. Find the small button on the circuit board. Hold down the button. While holding down the button, power the DVR. Be careful not to touch anything else as this is now powered. After 20s the DVR should start a factory reset. This erases everything. Share this post Link to post Share on other sites
