After LOTS of futzing around, I finally got it to do the firmware upgrade.
It now almost works as it should, but still no gold star.
The audio coming out of the DB10 when talking, is very low. I've tried this with two different phones, same results.
Any outdoor background noise will easily drown it out.
The audio transmitted to the phone, is also VERY low. Again, unless your in a quiet spot with your phone, forget it.
Motion detection now shows a still shot, it didn't before. Motion range adjustments seems to actually work.
The SD card I had handy was a 64gb Sandisk Ultra, that works fine in other devices, but the DB10 won't recognize it at all.
The other SD card that I had working with it before is in another camera that is installed, I'll have to take that cam down and try that SD Card again, but not this weekend, it's toooooo hot.
At least you can now successfully answer a call, see the video of the person, and talk back and forth, but neither of you may hear it.
The battery level and the Wifi signal meters do work in Lechange. And seem to be accurate.
The time is now set correctly.
Overall, sad, very sad on Dahua's part. Maybe in another 6 months, they'll get to work.
Have I mentioned the Lechange app SUCKS.
