Annke Firmware to Hikvision Firmware: HOW TO

No need to flood the forum with the same question in multiple threads.

Try a faster shutter.

 
Is there a firmware for I91BK (CZ504)? There's a bug with the ONVIF status not resetting back to IDLE after a PTZ move in the current FW V5.7.1 build 230706.
 
Thanks!

I was looking at that one earlier, but it has a different resolution: 2560x1440 (Hikvision) vs 3072x1728 (Annke). It seems that Annke might use some modified version of the firmware?

Edit: I would be okay with the resolution downgrade, just don't want to brick the camera.
I YOLOed the upgrade, it went fine, camera works, but the ONVIF bug still remains.
