Thanks again, if they don't have it, ask if there is an easy recovery if the FW is bad, corrupt or something. (I imagine there should be a failsafe if the FW isn't for the NVR it would fail to update and the NVR remain functioning) If they don't want to give you the FW, ask if the file name is what file name I have and that'll work. (if you have to go back and forth or they don't wanna be bothered, don't push them I'll sort it)
I really appreciate it, I have a thread around here where I've been trying to sort out my NVR problem since September!! LOL, you would not believe the time and effort I've put into trying to find the problem and fix, so it has to be the NVR in someway, physically or within the firmware.
If I had the money I would have just bought another NVR, but in the next day or so I will attempt the upgrade if the FW is correct, or atleast less doubt of it not being correct.
My situation is sort of that, the seller from aliexpress deleted their account or was banned so I was no longer able to communicate with them, but I'm sure they wouldn't have helped with FW anyways.
Here is a link to my thread if you are curious, lol

Thanks so much, if anything I can ever do to help you, I will!
