DVR4-4680XU Password Reset via USB Firmware Reflash

NOTE¹: If your DVR4-4680XU recorder has a firmware V1.0.10 and older, the only way to reset your forgotten password is by reflashing the recorder using a special firmware via USB drive. Please note that this upgrades your recorder's firmware to V1.0.14 keeping all your data including video recordings intact.

NOTE²: If you have an 8ch recorder (DVR8-4680XU), please follow this guide instead.

You will also need your recorder's MAC address as your Recovery code. Check this article if you need help finding this information.

Quick install steps

1. Prepare a flash drive or USB - it needs to be on FAT/FAT32 for it to be read; there is no need for an external HDD as the files are small. 
2. Download the recovery firmware file HERE and extract it to the root directory of your flash drive.

3. Plugin the flash drive and mouse to any of the available USB ports of the DVR (front or back).
4. Power-cycle or reboot the DVR. The recorder will automatically reflash the firmware. Once you see PART8: Upgrade is successful displayed on your screen, unplug your USB drive. Your recorder will automatically reboot again.

   • Tip: If your recorder does not initiate the firmware reflash, please check and verify if the extracted files are in the root directory of your drive, try a different USB drive or port on your recorder, and verify if your USB drive is using FAT/FAT32 partition!
5. At the login screen, click "Forgot Password" then "OK" to input your recorder's MAC address as your Recovery code. Input the characters in capital letters including colon (:). Click Unlock.
