The LDW931 screen will remain black for 3-5 seconds, then display a green progress bar. This takes approximately 90 seconds. Do not interrupt the power. If the screen flashes red, the update failed (usually due to a corrupted .bin file).
Once the progress bar completes, the LDW931 will reboot. Immediately go to Menu > Factory Reset and execute a reset. This clears any residual configuration conflicts from the old firmware.
Ensure the dash cam is completely off. If it has an internal battery, hold the power button for 10 seconds to discharge residual power.
Extract the downloaded .zip folder. Copy the LDW931_FW_V2.4.6.bin and AutoRun.inf files directly to the root directory of the SD card. Do not place them inside any folder.
If you own a dash cam or a driving recorder, you’ve likely heard the model number LDW931 thrown around in online forums and user groups. Known for its reliable loop recording, G-sensor, and (as the name suggests) Lane Departure Warning system, the LDW931 has been a staple for budget-conscious drivers. However, like any piece of technology, its performance hinges on one critical factor: keeping the firmware up to date .
Insert the SD card into the LDW931. Now, connect the camera to a USB power source (not your car’s 12V socket yet—use a wall adapter). Do not press the power button manually.
