How to Fix a Dead or Locked DVR by Reprogramming the BIOS Chip
If your DVR suddenly shuts down, won’t turn on, has no display, or is password protected and you don't know how to fix it, you can reprogram the BIOS chip. This will restore the DVR to working condition or unlock it. The problem is usually caused by a corrupted BIOS.
How to Fix Your DVR BIOS
Get a programming device from a local store or an online site.
Download the DVR Firmware (Bios Dump) file from the link below.
Open the DVR and carefully remove the BIOS chip to avoid damage.
Place the chip in your programmer, read it, and save a backup on your computer.
Reprogram the BIOS chip using the downloaded BIOS file.
Once done, put the BIOS chip back in the DVR and turn it on.
If the issue isn’t fixed after reprogramming, the problem may be hardware-related.
All our BIOS files are guaranteed to work. If your BIOS dump file isn't listed, please email us, and we'll update it as soon as possible.
