I just used this to recover one of my DS-2CD3132F-IW cameras.
Odd thing is the CN version wouldn't install but the EN worked just fine.
Overall steps followed:
1. Connected the camera to the same LAN as my workstation (ip: 192.0.0.128/24)
2. Started the
TFTP software with the BrickFix540-CN .dav file, this didn't work (I was watching the firmware update process via the TTL header)
3. Closed the TFTP software and renamed the files to use the BrickFix540-EN .dav file, this loaded and my camera finished then rebooted. As soon as you see the camera say "Update Complete" pull the power cord on the camera.
4. Close TFTP server, re-apply power, the camera attempted to boot into normal mode, failed, sat around for a little while then rebooted into Min mode (4-5 minutes). You will know when it is in min mode as the Batch configuration tool by Hikvision will display that. Also, telnet was operational on the camera.
5. Set the
custom firmware downgrader as the .dav file for the TFTP server (change it to digicap.dav) and started the TFTP server, rebooted the camera and it pulled down this file. Once complete it sat for 1-2 minutes then rebooted automatically. Once it did that it started up normally and is now running v5.2.5. Again, the English version worked for me, the Chinese version wouldn't take.
Hope that helps someone.
