theprez 0 Posted January 14, 2012 Hello, Attempting to upgrade one of our units to the latest firmware off of Bahamas' Security website....I extracted the .bin file from the .rar compressed file and put it on a USB thumb drive. When I try to upgrade, I get "open file failed". I've reformatted the USB drive to FAT and FAT32 - same error. Any suggestions? Dahua 2.608.0000.6.R Firmware Share this post Link to post Share on other sites
