Emergency Firmware Upgrade Guide

This method of updating a Cobra DVR wipes the system configuration and overwrites the operating system. Recorded footage is kept as this does not affect the HDD.

  1. Download the correct Emergency Update file for your DVR from www.cctvcommunity.co.uk. Check you have the right model name.
  2. Plug a USB memory stick into your PC. The filesystem must be in FAT32 format.
  3. Open the .zip file from your Downloads folder. Inside this file is another folder, named EMERGENCY_FW_UPGRADE
  4. Extract this folder to the USB drive. You can do this by drag-and-drop, or use the Extract option at the top of the window.
  5. Turn off power to the DVR and insert the USB stick into any port on the DVR.
  6. Turn on the power and wait for a black screen and white text to be displayed.
  7. Wait until the message changes and the DVR starts beeping.
  8. Remove the USB stick and reboot the DVR.
