Is there an easy way to change firmware backwards? I have 28 Dahua cams on Blue Iris and it locked up today.

I have all the cams set at 15 fps but seems that the fps bug is happening to every cam i have except the PTZ's.

There all a mix of 5231, 4231's every one of them says there running 30fps in BI. When i go into the cam itself and set for 15 BI sees that for a minute or 2 then goes back to 30fps.

Anyone have any ideas how to get fps forced to 15 or an easy way to go back on the firmware?

There all running
