oh my god thank you so much this worked like a charm now running the latest firmware on my crappy 4ch sunluxy h.264 DVR
all u need to update your dvr is to download DVR_Firmware.rar from http://drivers.amazplus.com/download/ put the files on a usb formatted with fat32 power on your dvr with the usb stick inserted and navigate to the system update page and bing your done
its also worth noting for all of you that forgot your admin passwords that this firmware resets all user data
